I do not see the option to exports video formats with alpha channels. I feel like it used to be an option, maybe in Video AI?
Specifically, ProRes 4444 is a critical intermediary codec for animation pipelines.
Even an option et export a black/white track matte would be beneficial.
Currently, alpha channel can only be supported with Quicktime animation codec for video formats in the app, or swapping to image sequences and using PNG or TIFF files.
The research team and devs are continuing to look into other options for the future to support other workflows though.
