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.

Drag and drop the alpha video into Video 2 track. Disable the Toggle Track Output box to make the video invisible.
Drag and drop the main video to apply the alpha video into Video 3 track.
- Optionally, you may adjust the size of the main video.
Drag and drop the Channel/Set Matte, in the Effect
