How to export only the avatar

What to do if you want to only want to download video of the avatar without any background?

Best way to currently do this is:

1. Create the video in Synthesia with our pre-made "Green screen" background, 
2. Export the video,
3. Cut the background out with one of the video editing tools (most video editing tools now support this functionality, e.g. iMovie, After Effects, Premiere Pro).
