Exported MP4 Alpha Channel Video Transparency not showing in FCP
I exported an animation from Motion to mp4 with the Export Movie dialog Color channels set to "Color + alpha". The result is a file with a default black background color. I believe the alpha channel is not encoded to the mp4 since Scoop! returns the line:
Chroma subsampling : 4:2:0
Motion project properties tab says:
Background: Transparent
And I thought I did as I should, but did I forget some extra setup in Motion before exporting?
FCP 10.5.4
Motion 5.5.3
