Please, how could I set the FFMPEG to premultiply (and bake) Alpha channel into .mp4 properly? An example and my settings are in the attachment.

The .mp4 is meant to be a preview of the sequence (I don't expect the .mp4 to contain an Alpha channel)

So far this argument seems to solve the problem:

-vf premultiply=inplace=1
