Exporting an Alpha Video

If you would like to export an alpha video in order to mask out other videos with external video editing tools, then please follow the steps below:

1. Prepare an iClone project. Remove the Sky and optionally remove the Terrain.

   Sky On	Sky Off

2. Click the Project Settings button on the play bar, disable the Activate Image box so that the background turns to a solid color.
   
3. In the Render panel, scroll to the 3D Stereo section and disable the Enable Stereo Vision Output box.
4. Leave the other settings in default. For more information, please refer to the General Output Settings section.

Using Alpha Videos in Video Editing Tools

The exported alpha video can be imported into any video editing tool to create frame or special overlaying effects. We will use Adobe Premiere as an example in the following case.

1. Drag and drop the background video into Video 1 track.
   
   
2. Drag and drop the alpha video into Video 2 track. Disable the Toggle Track Output box to make the video invisible.
   
   
3. Drag and drop the main video to apply the alpha video into Video 3 track.
   
   
4. Optionally, you may adjust the size of the main video.
5. Drag and drop the Channel/Set Matte, in the Effect panel, onto the main video.
   
   
6. In the Effect Control panel, collapse the Set Matte effect and set the two settings as shown in the illustration below.
   
   
7. Export the video.
