# OpenShot Video Editor Manual – v1.4

## Introduction

OpenShot Video Editor is a program designed to create and edit videos on Linux. It can easily combine multiple video clips, audio clips, and images into a single project, and then export the video into many common video formats.

OpenShot is a non-linear video editor, which means any frame of video can be accessed at any time, and thus the video clips can be layered, mixed, and arranged in very creative ways. All video clip edits (trimming, cutting, etc...) are non-destructive, meaning that the original video clips are never modified.

You can use OpenShot to create photo slide shows, edit home videos, create television commercials and on-line films, or anything else you can dream up.

### Features Overview:

## Getting Started

### To Launch OpenShot Video Editor

You can start OpenShot in the following ways:

#### Applications menu

Choose Sound & Video >OpenShot Video Editor.

#### Command Line

To start OpenShot from a command line, launch a Terminal and type the following command, then press Return:

`openshot` [filename]

The optional [filename] parameter can be either an audio or video file, or an OpenShot project file (*.osp). Multiple files can also be specified (with spaces between each filename), and all files will be imported into a single instance of OpenShot.

#### Open With...

To start OpenShot from Nautilus, right-click on an image, video, or audio file, and choose Open With > OpenShot Video Editor. Or choose Open With > Open with Other Application > `openshot`.

## Learn OpenShot in 5 Minutes!

Using OpenShot is very easy, and this tutorial will take you through the basics in under 5 minutes. After this tutorial, you will be able to make a simple photo slide-show with music.

### Step 1 – Import Photos & Music

Before we can begin making a video, we need to import files into OpenShot. Drag and drop a few images (*.JPG, *.PNG, etc...) and a music file (most formats will work) from your Desktop to OpenShot Video Editor. Be sure to drop the files where the arrow in the illustration is pointing to.

### Step 2 – Arrange Photos on Timeline

After you have imported some files, the next step is adding them to the timeline and arranging them. Click on each photo (one at a time), and drag them onto Track 2 on the timeline. Drag and drop the photos (also known as clips) to arrange them.

### Step 3 – Add Music to Timeline

To make our photo slide-show more interesting, we need to add some music. You should have imported a music file in step 1. Click on the music file, and drag it onto Track 1 on the timeline.

### Step 4 – Preview your Project

To preview what our video looks & sounds like, click the Play button under the preview window. Click the Play button again to pause your video. Remember, if you need to re-arrange any clips, just drag and drop the clips to move them.

### Step 5 – Export your Video

Once you are happy with your photo slide-show video, the next step is to export your video. This will convert your OpenShot project into a single video file, which should work on any Linux media player (such as Totem, VLC, etc...) or websites (such as YouTube, Vimeo, etc...).

Click on the Export Video icon at the top of the screen (or use the File > Export Video... menu). Choose from one of the many preset export options, and click the Export Video button.

### Step 6 – Enjoy OpenShot!

You should now have a basic understanding of how OpenShot works. Importing, Arranging, Previewing, and Exporting. Hopefully this tutorial took less than 5 minutes for you to complete. Please read the rest of this manual for a more detailed understanding of OpenShot, and it's advanced features. Enjoy!

## Main Window

OpenShot Video Editor has one main window which contains most of the information, buttons, and menus needed to edit your video project.

### Overview

Id | component | description
1 | Main Toolbar | Contains buttons to open, save, and export your video project.
2 | Function Tabs | Copy text Switch between Project Files, Transitions, and Effects.
3 | Project Files | Switch between Project Files, Transitions, and Effects.
4 | Preview Window | This is the area that the video will playback on the screen.
5 | Edit Toolbar | This toolbar contains toggle buttons used for editing, trimming, and splitting clips.
6 | Zoom Slider | This slider will adjust the time-scale of your timeline.
7 | Play-head / Ruler | The ruler shows the time-scale, and the red line is the play-head. The play-head represents the current playback position.
8 | Timeline | The timeline visualizes your video project, and each clip and transition in your project.
9 | Filter | Filter the list of items shown (project files, transitions, and effects) by using these toggle buttons and textbox. Enter a few letters of what you are looking for, and the results will be shown.

### Main Toolbar

The main toolbar contains buttons to quickly create and save your project, undo and redo actions, import files, and export your video. All of these functions can also be accessed through the File and Edit menus.

Id | component | description
1 | New Project | Create a new OpenShot project file (*.OSP).
2 | Save Project | Save the current project. If no project has been created, a dialog screen will open to gather more information.
3 | Undo | Undo the last action
4 | Redo | Redo the previous action
5 | Import Files | Import 1 or more files into your current OpenShot project.
6 | Export Video | Export the current project to a single video file.

### Function Tabs

These tabs let you switch between 3 different functions: Project Files, Transitions, and Effects. The items in these tabs can be dragged and dropped onto the timeline.

### Project Files

The Project Files section contains all files that have been imported into your project. Before you can add an image, audio file, or video file to your project timeline, it must first be imported into your Project Files section.

### Preview Window

The Preview Window is what controls the playback (or preview) of your video project. Clicking the buttons under the preview window controls the playback, and outputs video to this area. The size of this area can be modified by clicking and dragging on the handles (or lines) around this section.

Id | component | description
1 | Skip to Beginning | Skip to the very beginning of the project.
2 | Rewind | Rewind the video from the current playback position.
3 | Play/Pause | Play or Pause the playback of your project.
4 | Fast Forward | Fast forward the video from the current playback position.
5 | Skip to End | Skip to the end of the project.

### Edit Toolbar

The Edit Toolbar lets you toggle between different edit modes for the timeline. When moving, trimming, and slicing clips, it is necessary to change the edit mode using this toolbar.

Id | component | description
1 | Add Track | Add a new track to the top of the stack.
2 | Select Mode | Select mode allows you to click and move clips.
3 | Razor Mode | Razor mode allows you to split a clip where ever you click. If snapping is enabled, clicking near the play-head (the red line), will slice the clip exactly on the play-head.
4 | Resize Mode | Resize mode allows you to grab the edges of a clip and drag to resize (or trim) the clip.
5 | Snap Mode | Snap mode allows clips to snap (or jump) to the nearest clip or play-head (if any are close) when you drop them. Transitions will snap to nearby clips. Also, clips and transitions will snap to the play-head's position.
6 | Add Marker | Add a new marker, which allows you to quickly jump back to this exact point while previewing.
7 | Previous Marker | Skip to the previous marker (if any).
8 | Next Marker | Skip to the next marker (if any).

### Zoom Slider

The zoom slider allows you to change the time-scale of the timeline. Zoom in to see the timeline more closely, or zoom out to see the entire project without scrolling. You can either click the zoom buttons (on the left and right), or slide the zoom slider. When dragging the slider, it will update the timeline when you pause or stop moving it.

### Timeline

The timeline visualizes your project in a very graphical way. Each clip is represented by a yellow rectangle. Each track is represented by a blue rectangle. The Play-head (red line) represents the current playback (or preview) position of your project.

Click anywhere on the ruler to jump to that point in time. If you drag along the ruler, it will “scrub” the video, which is a fast, rough way to preview your project.

Id | component | description
1 | Ruler | The ruler shows the current time-scale of the timeline.
2 | Play-Head | The Play-head represents the current playback position of your preview window.
3 | Clip | A clip represents an audio, image, or video file.
4 | Track | A track is similar to a layer. The higher tracks show video and images above the lower tracks. There is no limit to how many tracks a project can have.

### Tracks

OpenShot uses tracks to layer videos and images. The top most track is the top layer, and the bottom track is the bottom layer. If you are familiar with layers in a photo editing application, then you should be quite familiar with this concept. OpenShot will mix each layer together, just like a photo editing application.

For example, imagine a 3 track video project. A sunset image should be used as the background, an image with lots of circles should be in the middle, and a logo should be on top.

Id | component | description
1 | Top Track | Clips on this track will be on top. Logos and watermarks should be on this layer. The OpenShot logo is on this track in the illustration.
2 | Middle Track | These clips are under the top track, but above the bottom track. The image with circles is on this track in the illustration.
3 | Bottom Track | These clips are under all other tracks. The sunset is on this track in the illustration.

### Controlling Playback of Video

Playing, Pausing, and Seeking are very important features in a video editor. While you are creating a video project, you will need to playback the project over and over again. While clicking on the Play button is an easy way to accomplish this, there are many faster ways.

#### Playback Methods

There are 8 ways to control the video playback in OpenShot.

1. Click the Preview Toolbar (Play, Fast-forward, etc...)

2. Dragging the Slider above the Preview Toolbar

3. Dragging the Play-Head on the Ruler

4. Clicking on the Ruler at any point

5. Using Keyboard Shortcuts (J, K, L keys)

6. Using the Arrow Buttons (Left, Right, Up, Down)

7. Using SHIFT + Arrow Buttons (Left, Right, Up, Down)

8. Using the Space bar key (Play / Pause)

9. Double-clicking on a user-defined marker

## Keyboard Shortcuts

A keyboard shortcut is a key (or keys) on the keyboard that saves you the trouble of moving your mouse and clicking. It is often faster to type a key, than to point and click. Here are all keyboard shortcuts in OpenShot:

key | description
J | Rewind the video playback
K | Pause / Play
L | Fast-forward the video playback
Space bar | Pause / Play
Up | Seek to previous maker (if any)
Down | Seek to next marker (if any)
Left | Step backwards one frame (frame stepping)
SHIFT + Left | Step backwards one second
Right | Step forwards one frame (frame stepping)
SHIFT + Right | Step forwards one second
TAB | Switch between Resize and Select mode
CTRL + Scroll Wheel | Zoom in & out of the timeline
CTRL + Home | Seek to the beginning of the timeline
CTRL + End | Seek to the end of the timeline
C | Slice all clips at the play-head position
CTRL + N | Create a new project
CTRL + O | Open an existing project
CTRL + F | Import a file (audio, video, or image)
CTRL + I | Import an image sequence

CTRL + B | Create a new animated title
F11 | Toggle full-screen mode
F1 | Launch the help file (if installed)
CTRL + D | Capture and save the current frame of any non-audio clips that are overlapping the play-head, and add them to the project files.
M | Add a marker to the timeline
Middle Mouse click | Opens clip properties window
CTRL + Drag clip or transition | Restricts movement of clip or transition to vertical only
SHIFT + Click | Removes the clip or transition that was clicked
SHIFT + Remove Clip (menu item) | Closes the gap on the timeline left by the deleted clip

## Projects - Create, Open, and Save

OpenShot needs a project file to save the information that makes up a video project. Information such as the name and location of your project, video and audio files, timeline information, which clips have been trimmed, arranged, etc...

When OpenShot is launched, it creates a new project file automatically. You can start using OpenShot immediately, without first creating a project.

Project files have an .OSP file extension (ExampleProject.osp). Also, project files need a /thumbnail/ folder, which contains all of the thumbnails in your project. If you move a project file, be sure to move the /thumbnail/ folder also.

Project File | /home/user/Desktop/ProjectA.osp
Thumbnail Folder | /home/user/Desktop/thumbnail/

### Create a Project

There are 2 ways to create a project file.

#### Method 1 – File Menu:

Choose File >New Project. The New Project screen will open. Change the project name, project type, length of timeline, and then click “Save Project”.

#### Method 2 – Save Default:

Since OpenShot creates a project by default when you launch the program, you can simply choose File >Save. The Save Project screen will open. Change the project name, project type, length of timeline, and then click “Save Project”.

### Save Project Screen

Clicking New Project or Save Project will result in this screen being shown.

Id | component | description
1 | Project Name | The name of your project file (.osp file extension)
2 | Project Folder | The folder location to save your project file to.
3 | Project Length | The maximum length of the timeline. However, the length of the timeline will automatically grow, if and when clips exceed the length.
4 | Project Type | This affects the preview window. It determines the size, aspect ratio, and frames per second of the video files you are previewing. It is recommended that you edit in the same profile you are planning to export (for the best results).
5 | Project Type Details | This table previews the project type details, such as size, aspect ratio, and frames per second. When you change the project type dropdown, it will update this table.

### Open a Project

To open a project, choose File >Open Project. The Open Project dialogue is displayed. Select the project file (*.osp) that you want to open, then click Open Project.

If you are opening a recent project, choose File >Recent Projects. This is often the fastest way to open a project from within OpenShot.

If you want to launch OpenShot and have your project automatically opened, double click on the .OSP file (on your computer), and choose `openshot` as the command.

## Import Files – Audio, Video, and Images

Before you can use a clip on the timeline, you must first import the clip into your project. There are a few different ways to import a clip. The most common way is to drag and drop files from your computer into the Project Files section of the screen.

There are 4 different methods to import a clip.

### Method 1 - Drag & Drop

1. Run OpenShot

2. Drag and drop multiple files at once from your Desktop to the Project Files tree.

### Method 2 - Drop Folder

1. Run OpenShot

2. Drag and drop a folder full of media files from your Desktop to the Project Files tree.

   * All audio, video, and image files will be imported from this folder

### Method 3 - Open With

1. While browsing files in Gnome, select 1 or more media files

2. Right click on the selected files, and choose Open With Other Application...

3. Choose OpenShot Video Editor (or the `openshot` command)

   * Even after you start working in OpenShot with your files, you can still return to the file system, and right click on more files and choose OpenShot . It will add them to the currently running instance of OpenShot.

### Method 4 - Import Button

1. Run OpenShot

2. Click the Import Files toolbar button

3. Select 1 or more files, and click Import

## Image Sequences

One of the most powerful features in OpenShot is the ability to import sequences of images. A sequence of images is really just a folder full of images that are named very similar, and of course named sequentially. Each image file represents one frame of video. So for a 30 second long clip, with 30 frames per second, you would have 900 image files. Although image sequences can be tough to work with (because of the sheer volume of files), it can do just about anything.

To import an image sequence, follow these steps:

### Locate an Image Sequence

Many programs can generate an image sequence. For example, in Blender (a 3D animation package), you can create a great animated title sequence and export it as a series of named .PNG files (with transparency). It will create a folder on your computer that contains all of the image files.

### Import the Image Sequence

Choose the File > Import Image Sequence menu option, and that will launch the Image Sequence dialogue.

Choose the folder location of your image sequence, and the file naming pattern. Not all image sequences are named the same way. For example, Movie_0001.JPG is different from Movie_1.JPG. Once you enter the correct filename pattern, click Import Image Sequence.

### Drag and Drop Image Sequences

The easiest way to import an image sequence, is to drag and drop just a single image from the sequence into the “Project Files”, or use the Import Files screen and import just a single image. It will then prompt you to import the entire image sequence. Using this method will automatically determine the file name pattern, and set all the correct settings for the sequence.

### Add to Timeline

Drop your new image sequence on the timeline. It is represented by a single clip, just like a regular video clip.

### Create an Image Sequence

If you do not already have an image sequence, it is easy to create one. Just right-click on any video file in your Project Files and choose Convert to Image Sequence. It will create a new folder, and export every frame as a .PNG image file. It will also add a reference to your new image sequence in the Project Files section automatically.

### Edit an Image Sequence

If you want to edit a sequence of images, we recommend using The Gimp (an open-source image editor). It has plug-ins to assist in editing large sequences of images, and can simplify the process of editing, saving, and opening the next image in a sequence. You can then touch up each frame, remove red-eye, add glowing effects to light sabers, erase wires, etc... There is really nothing you can not do with a frame by frame editing approach, but it does take a lot of effort.

#### Gimp Animation Package (GAP)

GAP is a plug-in for The Gimp, which assists in editing image sequences. It can quickly save the current image and load the next image in a sequence. It can also use key-frames to apply effects across many frames, or even create animations. If you need to edit an image sequence, you should definitely take a look at GAP.

#### Screenshot of Gimp Animation Package

## Manage Files & Folders

When making a video, you will need to import many different files into your project, including audio, videos, images, titles, overlays, sound effects, and more. This can quickly get out of hand, and make your list of project files too long, which will slow you down looking for the right file.

If your project has too many files (which is up to you to decide), you can use labels, filters, and folders as a way to organize your files.

### Labels

Each file has a column for a Label. A label is any phrase or phrases that helps you identify what this file is going to be used for. For example, “Scene 1”, “Intro”, “Title”, “Credits”. There is no right or wrong way to use a label, just enter any text that helps you identify a file.

### Filters

The Project Files section has filter buttons and a textbox to help you find files quickly. The filter buttons, Video, Audio, and Image, will quickly filter the list of files down to those file types. Entering any text into the filter textbox will only show files that contain that text in their filename or label. So, this feature can be combined with labels, to create a powerful search and organization system.

### Folders

If labels and filters are not enough to organize your project files, you can also create folders inside your project to help group files together.

### Create a Folder

1. Right click on the Project Files section.

2. Choose Create Folder...

3. Enter a name for your folder.

### Move Files to a Folder

1. Be sure you have created a folder first.

2. Right click on 1 or more files in the Project Files section.

3. Choose Move File(s) to Folder.

4. Choose a folder.

### Remove a Folder

1. Right click on a folder

2. Choose Remove

   * Be sure to move all files out of a folder before removing it.

## Add Files to Timeline

Once you have imported files into your project, the next step is to add them to the timeline.

### Drag and Drop

To add a file from your Project Files to the timeline, follow these steps:

1. Click on a file.

2. Drag over the timeline and drop it.

3. The clip will now be added to the timeline.

   * You can only add 1 file at a time using this method.

### Add Multiple Files to the Timeline

If you would like to quickly add multiple files to the timeline at the same time, there is an Add to Timeline feature. To use this feature, select all of the files you would like to add to the timeline, and right-click and select Add to Timeline.

The Add to Timeline screen can also apply fade in and fade out settings to each clip, add transitions between the clips, or simply stack the clips back to back on the timeline. The files will be inserted at the position of the play-head.

Id | component | description
1 | Start Time | This is the location on the timeline (in seconds) where the files will be added. It will default to the position of the play-head.
2 | Top Track | The top track is the primary track where clips will be added. If no transitions are being used, only the top track is needed.
3 | Bottom Track | The bottom track is used when transitions are needed, and the clips alternate between the top and bottom track, with transitions between them.
4 | Fade | The type of fade to apply to a clip.
5 | Fade Length | The length (in seconds) of the fade.
6 | Transition | The type of transition to add between clips. You can also choose Random Transition, if you do not want the same transition being used over and over again.
7 | Transition Length | The length (in seconds) of the transition.
8 | Move Up | Move the selected files up in the list.
9 | Move Down | Move the selected files down in the list.
10 | Shuffle Files | Shuffle the files and put them in a random order.
11 | Remove File | Remove the selected files from this screen.

## Move & Trim Clips on Timeline

Once you have files (also referred to as clips) on the timeline, we need to arrange them onto tracks, and put them in the correct order. Also, we will need to trim off the beginning and endings of the video clip (if needed).

### Move a Clip (Select Mode)

1. Switch to Select Mode (this is the default mode)

2. Click on a clip.

3. Drag the clip to a new position on the timeline, and drop it.

   * If snapping is enabled, the clip will jump to any close-by clips (or the play-head, if it is close-by).

### Trim a Clip (Resize Mode)

1. Switch to Resize Mode, by clicking on the resize icon.

2. Move you mouse cursor over the right or left edge of a clip.

3. Drag the edge of the clip to trim the video.

   * As you drag the edge of the clip, the preview window will display where the clip will begin or end (based on which side of the clip you are dragging).

### Slice a Clip (Razor Mode)

1. To slice a clip into 2 pieces, switch to Razor Mode .

2. The mouse cursor will change to a dotted line & razor icon.

3. Click on a clip at the point you want to cut / slice it.

   * If snapping is enabled, the razor will jump to the play-head position, if it is close-by.

### Edit Toolbar

The Edit Toolbar lets you toggle between different edit modes for the timeline. When moving, trimming, and slicing clips, it is necessary to change the edit mode using this toolbar.

Id | component | description
1 | Add Track | Add a new track to the top of the stack.
2 | Select Mode | Select mode allows you to click and move clips.
3 | Razor Mode | Razor mode allows you to split a clip where ever you click.
4 | Resize Mode | Resize mode allows you to grab the edges of a clip and drag to resize (or trim) the clip.
5 | Snap Mode | Snap mode allows clips to snap (or jump) to the nearest clip or play-head (if any are close) when you drop them.
6 | Add Marker | Add a new marker, which allows you to quickly jump back to this exact point while previewing.
7 | Previous Marker | Skip to the previous marker (if any).
8 | Next Marker | Skip to the next marker (if any).

## Separate Audio From Video

OpenShot can separate the audio and video of a clip, if needed. If you only want to play the audio of a clip, or only play the video with no audio, then follow these steps:

### Only the Video

To only play the video of a clip, click on the speaker icon, located on the clip. This will mute the audio for this clip. Or if you want to mute the audio for the entire track, click the speaker icon on the track.

### Only the Audio

To only hear the audio of a clip, click on the eye icon, located on the clip. This will hide the video output. Or if you want hide the video output for the entire track, click the eye icon on the track.

## Duplicate Clips

A very useful feature in OpenShot is the ability to duplicate clips, transitions, and masks. To duplicate an item, right-click on the item (such as a clip or transition), and choose Duplicate. This will add an exact copy of the duplicated item to the timeline. Including the IN and OUT points, effects applied to the clip, and key-frame animation settings.

A common use of the Duplicate feature, is to trim a video clip down to a specific scene, and then duplicate the clip. Once you have two identical clips, you can mute the audio on one, and hide the video of the other. The is a quick way to separate the audio and video of a clip. Now you can offset the audio of the clip, or continue the audio of the clip, while trimming the video down. This is often used in films, when two people are talking. They continue to play the audio from the first person talking, while showing the reaction of the second person.

## Clip Properties

Each clip in OpenShot has many properties that can be manipulated. However, because it is not possible to display and adjust all of the settings on the timeline, this screen was created. It lets the user adjust every possible setting and property that a clip has, including Length, Speed, Volume, Size, Position, Aspect Ratio, and many others.

### Launch the Clip Properties Screen

To launch the clip properties screen, right-click on a clip and choose Properties, or click your middle mouse button on a clip.

### Preview Changes

To quickly preview what your new settings will produce, click the Play button or drag the preview Slider. You can preview your changes over and over again to get them just right. No changes are saved to your timeline until you click the Apply button.

### General Tab

The general tab has the following properties:

component | Description
Position on Timeline | The point on the timeline at which the clip begins to play (in seconds).
Enable Video | Output video for this clip
Enable Audio | Output audio for this clip

### Length Tab

The length tab provides information on the beginning, end, and total length of a clip. By adjusting these values, you can delay when a clip starts, end the clip sooner, or both. Use the Play button to preview your changes. Practice by adjusting these values without using the Resize tool.

The length tab has the following properties:

component | description
In (seconds) | The point in the clip in which to start playing, in seconds.
Out (seconds) | The point in the clip in which to stop playing, in seconds.
Length (seconds) | The length of the clip is calculated based on the IN and OUT points.

### Speed Tab

The speed tab speed consists of a simple mode and advanced mode. In the simple mode, using predefined values, you can speed up the clip to 16x normal speed or slow down the clip to 1/16 normal speed. Also, you can change the direction. The advanced tab let's you set a high-precision speed decimal, instead of the simple predefined fractions.

Note: The speed tab is only displayed for video files. Also, the audio is not played when the speed is modified.

The speed tab has the following properties:

component | description
Speed | The second to start playing the video (decimal)
Direction | The last second of the video clip (decimal)
Advanced Speed | A high-precision decimal value for the speed of a clip. This value changes as the speed dropdown changes.

### Layout Tab

The layout tab has the following properties:

component | description
Key Frame | This dropdown determines which key frame you are working with. Each clip has 2 key frames, the start of a clip, and the end of a clip.
Height | The height of a clip (percent based). The larger the number, the taller the clip will be. The smaller the number, the shorter the clip will be. This only affects the current key-frame, not the entire clip.
Width | The width of a clip (percent based). The larger the number, the wider the clip will be. The smaller the number, the narrower the clip will be. This only affects the current key-frame, not the entire clip.
X | X position of the centre of the clip. The larger the number, the further to the right the clip will be. The smaller the number, the closer to the left the clip will be. This only affects the current key-frame, not the entire clip.
Y | Y position of the centre of the clip. The larger the number, the closer to the bottom the clip will be. The smaller the number, the closer to the top the clip will be. This only affects the current key-frame, not the entire clip.
Alpha | The alpha level of the clip. 100 = opaque. 0 = invisible. This only affects the current key-frame, not the entire clip.

### Audio Tab

The audio tab has the following properties:

component | description
Volume | The volume level of this clip. 0 = mute, 100 = max.
Fade In | Fade the clip in from mute to volume level.
Fade Out | Fade the clip out from volume level to mute.
Fade (Seconds) | The number of seconds the fade will last. The bigger this number, the more gradual the fade will be.

### Video Tab

The video tab can adjust the size, position, and alignment of a clip. Also, it can apply a fade effect to the beginning and ending of a clip, which is sometimes easier than using a transition. Because the fade is a property of the clip, it moves when you move the clip. So, unlike transitions, fades stay with the clip when you move them.

The video tab has the following properties:

component | description
Stretch Full Screen | Stretch clips to the size of the screen (based on project type).
Maintain Aspect Ratio | Do not distort the clip.
Horizontal Align | Alignment of the clip left to right.
Vertical Align | Alignment of the clip top to bottom.
Rotate | The number of degrees to rotate the image. This can be a negative or positive number, depending on which direction you want to rotate.
Fade In | Fade the clip in from transparent to opaque.
Fade Out | Fade the clip out from opaque to transparent.
Fade (Seconds) | The number of seconds the fade will last. The bigger this number, the more gradual the fade will be.

### Effects Tab

The effects tab can apply and manage multiple effects that are applied to a clip. To preview your clip with effects, use the Play button. Each effect can have many settings, so use the Play button as you change settings to see the result.

The effects tab has the following properties:

component | description
Effect List | This box has a list of all effects applied to this clip. Clips are processed in a top to bottom order.
Add | Add a new effect to this clip.
Remove | Remove the selected effect from the clip.
Up | Move the selected effect up in the list.
Down | Move the selected effect down in the list.
Effect Settings | This area will contain settings for the selected clip (if any).

## Key Frames

OpenShot can use Key Frames to animate a clip. A key frame is a point in time that contains many settings, such as size, position, and transparency. There are two ways to set key-frames in OpenShot, manually or with a preset.

### Preset Animation

Many preset animations are available, such as moving a clip from bottom to top of the screen or slowly zooming up on a clip. To add a preset animation to a clip, right-click on a clip, and choose Animate.

### Preset Layout

Many preset layouts are available, such as resizing a clip and positioning it to the corner of the screen or centreing a clip. To add a preset layout to a clip, right-click on a clip, and choose Layout.

### Manually

To manually create key frames, right click on a clip, and choose Properties. Switch to the Layout tab, and choose which key frame you want to edit from the dropdown.

Each clip has 2 key frames, the start of a clip, and the end of a clip. If there are any differences between the start and end key frames, OpenShot will interpolate the difference on a each frame, and thus animate the clip. The following properties are affected by key-frames: Height, Wight, X, Y, and Alpha.

For example, consider these key frames:

Start Key Frame: | X=-50, Y=0
End Key Frame: | X =150, Y=0

This would result in the clip animating from the left to the right side of the screen. The difference in the X setting is interpolated across all frames in this clip. The longer the clip, the slower the animation. The shorter the clip, the faster the animation.

If you want to statically change the size or position of a clip, just set the start and end key frames to the same value:

For example, consider these key frames:

Start Key Frame: | X=-50, Y=-50
End Key Frame: | X=-50, Y=-50

This would offset the clip to the top right of the screen. It would not animate, because the start and end key frames are the same value.

If you need to more than 2 key frames, slice the clip into many pieces, and at the beginning and ending of each slice, you can set the key frames, thus giving you the ability to make an unlimited number of key frames.

## Crop Effect

OpenShot can crop video and image clips using our Layout setting, found on the Clip Properties screen. Right click on a clip, and choose Properties. Then switch to the Layout tab.

To crop a clip, you need to zoom up on the part of the clip you want to see. Adjust the Height, Width, X, and Y settings to zoom up on the area of the clip you want to crop. Be sure to set both key frames to the same values. Use the Play button to preview your crop. Once you are happy with the crop, click the Apply button.

## Rotate Effect

If you need to rotate a clip 90 degrees, 180 degrees, or even animate the rotation around in circles, OpenShot has a Rotate effect which can help.

OpenShot has two types of rotation effects available, fixed and animated. To apply a rotation effect, switch to the Effects Tab on the main window, and drag the Rotate effect onto your clip.

To adjust your rotation settings, right-click on the clip and choose Properties. Then switch to the Effects tab on the properties window, and click on the Rotate effect. This will bring up a list of rotation settings that can be adjusted. Try changing each setting, and use the Play Button to preview the effect.

### Fixed Rotation

A fixed rotation can rotate a video 90 degrees, 180 degrees, or any number of degrees you need. It does not animate the rotation. This is useful when you record a video sideways, and need to rotate it. To use a fixed rotation, only adjust the settings with that start with “Fixed”. Be sure to adjust the other settings back to zero.

### Animated Rotation

An animated rotation can be used to spin a clip around in circles, or many other patterns. This can be a nice effect for titles, spinning newspapers, or other creative uses. To use an animated rotation, adjust the “Fixed” settings to zero, and only use the settings that start with “Rotate”.

### Simple Rotation

Each clip has a Rotate setting, which will rotate the clip without requiring an effect to be added to the clip. This can be modified on the Clip Properties screen, or by right-clicking on a clip, and choosing the Rotate menu.

## Title Editor

Like many video editors, OpenShot has a built-in title editor. It has some basic functionality to help you create titles for your video project. Here are the features of the title system:

1. Many Templates (Including a Solid Colour Template)

2. Easy Text Editing (title, subtitle)

3. Change Font and Colour (including alpha channel)

4. Change the Background Colour (including alpha channel)

5. Uses SVG Image Format (vector based)

6. Adds Titles to the Project Files Section

7. Integration with Inkscape (as the advanced editor)

However, if the basic editor is not powerful enough for you, any SVG image file can be imported and used as a title. The alpha channel (transparency) is respected, which means titles can be overlayed on top of other tracks, and will show the video through the transparent parts.

### Launch Title Editor

To add a new title, click the Title > New Title... menu option. This will launch the Title Editor.

### Create New Title File

Once the title editor launches, you need to select a template, and click the Create New Title button. This will make a copy of the template SVG title, and add it to your Project Files. Enter the name of the file, as it will be saved to your hard-drive.

### Title Editor Window

The title dialog allows you to choose a template, edit text, change colours, and create your own titles for your video project. Once you are finished editing your title, click the Apply button.

Id | component | description
1 | Choose Template | Choose a template SVG file to use as a title.
2 | Create Title Button | Click this button to create your copy of the SVG template.
3 | Edit Text | Launch the text editing window.
4 | Change Font | Change the size and family of the font.
5 | Font Colour | Change the font colour and alpha (transparency) level.
6 | Background Colour | Change the background colour and alpha (transparency) level.
7 | Advanced Editor | Edit this SVG title in Inkscape.
8 | Title Preview | Preview your title after each edit, colour change, or font change.

### Scrolling Titles / Credits

To create the effect of scrolling titles, you need to cut your title sequence into many different screen-sized titles.

#### Create Each Title Image

#### Offset Each Title on the Timeline

Add each title image of your scrolling credits to the timeline, set the length of each image to 7 seconds, and then offset them between two tracks. This can be done very quickly with the Add to Timeline feature.

#### Animate Each Title

Right-click on each title clip and choose Animate > Bottom to Top. This will create the illusion that your entire credits are scrolling from bottom to top in one continuous sequence, with no gaps. Be sure to overlap the titles (as show in the illustration) so there are no gaps between the titles.

## Animated Title Editor

Animated 3D titles are just as easy to create as simple image-based titles. The animated title system has the following features:

1. Many Templates

2. Easy Text Editing (title, subtitle)

3. Change Font and Colour

4. Transparent Backgrounds

5. Outputs an image sequence of PNG images (with alpha channel)

6. Adds Titles to the Project Files Section

7. Integration with Blender (a 3D animation application)

### Launch Animated Title Editor

To add a new title, click the Title > New Animated Title... menu option. This will launch the Animated Title Editor. Be sure to set the “Blender Executable” setting in the preferences dialog to the path of Blender (version 2.5+ is required).

### Create New Animated Title

Id | component | description
1 | Choose Template | Choose a template to use as a title.
2 | Preview Window | Preview any frame in the animation.
3 | Frame Selector | Choose any frame to preview in the animation.
4 | Refresh | Refresh the preview window, to reflect new changes.
5 | Edit Settings | Edit the various animation settings, including the title, font, colour, etc...
6 | Render | Generate an image sequence with the animated title, and add it the Project Files section.

## Transitions

Transitions are used to gradually move between 2 different clips. Many different transitions are available in OpenShot. They are easy to drag and drop onto the timeline, and can add lots of fun to a video project.

### Transition Screen

Id | component | description
1 | Transition Tab | This is the transitions tab. It contains a list of all transitions available in OpenShot.
2 | Transition List | This is the transition list. Select a transition and drag and drop it onto the timeline.
3 | Resize Tool | The resize tool can be used to resize a transition.
4 | Transition on the Timeline | Once you drop a transition on the timeline, it can be moved and resized just like any other clip. The transition snaps between tracks, and blends between the 2 tracks. If snapping is enabled, the transition will automatically resize itself to perfectly fit between 2 clips, and also automatically set the direction of the transition.

### Add a Transition

To add a transition, switch to the Transition Tab, and select a transition by clicking on it. Drag and drop the transition onto the timeline. It will snap between 2 tracks and automatically resize itself, if dropped where 2 clips overlap.

### Move a Transition

To move a transition, switch to Select Mode on the Timeline Toolbar, and drag it to a new position.

### Resize a Transition

To resize a transition, switch to Resize Mode on the Timeline Toolbar, and drag the left or right edge to a new size.

### Switch the Direction

Because transitions blend between 2 tracks, it is important to know which direction it is blending. On the transition, it has an arrow that shows the direction, top to bottom, or bottom to top. In general, the transition should go from the first clip to the next clip by timeline position.

To change the direction of a transition, right-click on a transition, and choose Switch Direction.

### Transition Properties

Just like a clip, a transition has a properties window. To launch the properties window for a transition or a mask, right-click on the item, and choose Properties. To save your changes, click on the Apply button.

Id | component | description
1 | Type | Mask or Transition
2 | Direction | The direction of the transition or mask. Up blends from the bottom clip to the top clip. And Down blends from the top clip down to the bottom clip.
3 | Softness | The softness of the transition. The bigger the number, the wider the wipe, and the smaller the number to narrower the wipe.
4 | Mask Threshold | The mask threshold is the amount of grey to use for the mask. The bigger the number, the more of the mask is used, the smaller the number, the less is used. Experiment to find the right threshold for a mask.

### Convert to Mask

A mask is very similar to a transition, except that a mask is static. It does not gradually change from one clip to the next. Instead, it mixes the 2 tracks at some predetermined point. A mask can be used to only show a small section of a clip, to show a border around a clip, to block out something from a clip. To experiment with a mask, simply convert a transition to a mask and watch what happens.

To convert a transition to a mask, right-click on the transition, and choose Convert to Mask.

### Create a New Transition / Mask

Transitions are just gray-scale images. They can be created in any graphics program. To add a custom transition or mask, select File > Import New Transition, and select a gray-scale PNG image file from your hard-drive. You will see this new image show up on the Transitions tab. This transition will be in localed in the /home/USER/.openshot/ folder.

### Remove a Transition

To remove a transition, right-click on a transition on the timeline, and choose Remove.

## Export Video

Once your have completed a project, you will want to export it to the correct format, based on your needs. OpenShot has many predefined formats to simplify this process. There are two modes to export a video in OpenShot, Simple Mode and Advanced Mode.

Both modes share a common area at the top of the screen, General Options. Name your video file (no extension) and choose an export folder.

### Launch Export Window

To launch the export window, click on the Export Video toolbar icon at the top of the main window, or choose File > Export Video.

### Simple Mode

OpenShot has many predefined export formats, which cover the most common export scenarios. Select a Project Type, such as DVD or Web, and then choose the Target, Video Profile, and Quality. If you select All Formats, it will give you a list of all common formats, and let you pick the one you want.

#### Upload to Web

Choose the Upload to Web option at the top of this screen to choose between YouTube and Vimeo. These are two very common video sharing websites. This will automatically set the export settings that are compatible with the selected video website, and launch the Upload Video screen once the video file has been created.

### Advanced Mode

The advanced options should only be used by someone familiar with FFmpeg, since it is so easy to create invalid combinations of codecs, formats, and bit-rate settings. However, if you are familiar with these settings, any FFmpeg supported format/codec/bit-rate can be used, which opens up dozens and dozens of additional formats that can be used during the export process. You can also export your video as an image sequence, which can be useful if you intend to import this video into a program that requires image sequences, such as Blender.

Also, if you first select values for the Simple Mode, and then switch to the Advanced Mode, it will preselect all of the Simple Mode settings.

## Upload Video

If you would like to directly upload a video to YouTube or Vimeo, choose File > Upload Video. Also, on the Export Video screen, you can choose Upload to Web, which will first export your project to the correct video format, and then display the upload screen.

Id | component | description
1 | Video File | Choose a video file to upload to YouTube. Be sure it's a compatible format with YouTube first, or it might not work correctly. If you first use the Export Video screen, you can choose Upload to Web, which automatically chooses a compatible format, and fills in this box for you.
2 | Upload To | Choose the video website you want to upload a video to.
3 | Title | Enter a title for the video.
4 | Description | Enter a description for the video.
5 | Credentials | Enter the username and password for the video website.

## Export to XML

Export your project to a powerful and flexible XML format, called MLT XML. This XML file can be used with Kdenlive and the melt command line.

## Project Types / Profiles

Every project in OpenShot must have a project type (also known as a profile). A profile determines the following playback & export settings for your video project: frame rate, height & width, aspect ratio, and pixel ratio.

Here is an example profile, for ATSC 1080i 60Hz:

description | ATSC 1080i 60Hz | Name of your profile as it will appear in OpenShot.
frame_rate_num | 30000 | Numerator of the frame-rate.
frame_rate_den | 1001 | Denominator of the frame-rate.
width | 1920 | Width of the video.
height | 1080 | Height of the video.
progressive | 0 | 0 = Interlaced, 1 = Progressive
sample_aspect_num | 1 | Numerator of pixel ratio.
sample_aspect_den | 1 | Denominator of pixel ratio.
display_aspect_num | 16 | Numerator of display aspect ratio.
display_aspect_den | 9 | Denominator of display aspect ratio.

OpenShot has over 40 predefined profiles / project types available. However, if you can not find a profile that works for your project, you can also create your own. You can manage the list of profiles with the Edit >Preferences > Profiles tab.

## Preferences

To configure OpenShot, choose Edit >Preferences . The Preferences dialog can adjust the default length of images, the default theme, and the default project type / profile. Setting these values can save you valuable time when starting a new project.

## Dependencies

OpenShot is programmed in Python, but has many dependencies, some optional and some required. If you are trying to manually install OpenShot or create an installation package for OpenShot, than this section is for you.

Id | Name | Debian Package Name | Notes
1 | Python | python | This is the primary language that OpenShot is programmed in. Python 2.5+ is required.
2 | GTK+ & Python Bindings | python-gtk2 | OpenShot uses GTK+, and needs the Python bindings for GTK.
3 | MLT (Media Lovin' Toolkit) | libmlt2, libmlt-data, libmlt++3, melt | MLT is an open source multimedia framework, designed and developed for television broadcasting. This has many additional dependencies which are not listed here. This library is used to create, edit, and playback videos.
4 | MLT Python Bindings | python-mlt2 | These are the Python bindings for MLT, which are required to use MLT from the Python programming language.
5 | GooCanvas Python Bindings | python-pygoocanvas | GooCanvas is used to render and animate the timeline. The Python bindings are required to use this library.
6 | Frei0r Video Effects | frei0r-plugins | (Optional) This library is used to add many additional video effects to OpenShot.
7 | FreeDesktop.org Standards Library | python-xdg | XDG is used to load icons, set mime-types, and other desktop integration features.
8 | Sox Audio Library | sox | Swiss Army Knife sound processing, used in the audio effects.
9 | Simple DirectMedia Layer | libsdl1.2debian, libsdl1.2debian-pulseaudio | SDL is used to display the preview window for video and play audio.
10 | Scalable Vector Graphics Library | librsvg2-common | SVG library required to process and display SVG images.
11 | Python Imaging Library | python-imaging | PIL is used to calculate image size information. Primarily used for the Animated Titles screen.
12 | FFmpeg File Format Library | libavformat52 or libavformat-extra-52 or libavformat-unstripped-52 | This provides MLT with the ability to understand different audio and video codecs. There are many different versions of libavformat, some with limited codecs and some with lots of codecs.
13 | Fontconfig | fontconfig | Fontconfig is a font configuration and customisation library. OpenShot uses the fc-list command to get a list of all installed fonts on the computer, for the Animated Titles screen.

## Become an OpenShot Developer

If you are a programmer (or wanting to become a programmer), and are interested in developing new features, fixing bugs, improving the user interface, or developing new themes for OpenShot, the following sections will explain the steps and processes you will need to follow.

### The Big Picture

OpenShot is a Python program made up of many different Python files (.py), images (.svg, .png), XML files (.xml), GTK+ XML files (.ui), and Blender project files (.blend). Python is an interpreted language, which means there are no files that need compiling or building to run OpenShot. If you change any of the source files, you just need to close and relaunch OpenShot to see the changes.

### Getting the Latest Source Code

OpenShot hosts the latest version of source code on LaunchPad.net, using the Bazaar version control system.

1. Install the Bazaar version control system. In Debian (or Ubuntu), you can type

   `$ sudo apt-get install bzr`

2. Tell Bazaar to create a local branch for your computer. This will create an /openshot/ folder in your home folder and download the latest source code into that folder. For example: /home/USER/openshot/

   `$ bzr branch lp:openshot`

3. If you already have an /openshot/ folder, just change your current directory to it, and run the following command to get the lastest version:

   `$ cd /home/USER/openshot/`

   `$ bzr pull lp:openshot`

4. Now you should have the latest source code for OpenShot. To launch OpenShot from this folder, you must run the following commands. Remember, you must already have the dependencies for OpenShot installed, which is covered in the next topic.

   `$ cd /home/USER/openshot/bin/`

   `$ ./openshot or python openshot`

5. If you have made some changes to the OpenShot source code, and want to see everything you have changed, run this command:

   `$ cd /home/USER/openshot/`

   `$ bzr status`

6. If you are unhappy with your local changes, and want to revert your changes, run this command:

   `$ cd /home/USER/openshot/`

   `$ bzr revert`

### Setting Up Your Environment

Once you have gotten the latest source code, the next step is to install all of the required dependencies. I would recommend installing OpenShot from your favorite package manager (such as Synaptic). This will install a version of OpenShot and all the required dependencies. This will not conflict with your local version of OpenShot source code. The only trick is to remember that the $ openshot command will launch the official version of OpenShot, and not your local version. So, you must remember to launch OpenShot with the following commands:

`$ cd /home/USER/openshot/bin/`

`$ ./openshot or python openshot`

Now that you have the latest source code and all of the dependencies, you can either use a text editor (such as gedit), or a full Python IDE, such as Eclipse or Aptana (with Pydev) to modify the source code. The advantage of using a full Python IDE is the enhanced debugging capabilities. It is beyond the scope of this document to teach you how to debug Python with Eclipse or Aptana, but there are lots of good tutorials online.

### Fixing Your First Bug

Now that you have a local version of OpenShot running, fixing bugs and adding new features is easy. Just modify the files, and re-launch OpenShot to see your changes. Of course, I can't tell you exactly how to fix a bug, that is up to you. So, good luck!

### Sharing Your Changes with the OpenShot Team

Once you have fixed your first bug or added a great new feature, the next step is to share it with the OpenShot Team, so we can be sure your changes get into the official version of OpenShot. The easiest way to share your changes is to create a patch (or diff). Use the following command to create a patch:

`$ cd /home/USER/openshot/`

`$ bzr diff > mychanges.patch`

This will create a file called mychanges.patch, which should have all of the changes for all the files you have modified. Of course, if you have created new files, you will need to compress those up into a ZIP or TAR file, and include them with your mychanges.patch file.

Next, create a new bug report on LaunchPad (or find an existing bug report), and upload your patch and related files to the bug report. That's it! The OpenShot team will be notified by email that a patch has been submitted. Now you can subscribe to the bug report, and follow along to see if there are any questions or comments about your patch.
