Need a way to streamline our keying workflow.
Currently rending/exporting clips with alpha channels in Premiere and After Effects takes too long. We need to be able to render/export in the background (through Media Encoder) so we can keep editing and hit our deadline each day; however, we can't seem to find an export setting that allows the clips to be rendered in Media Encoder with an alpha channel.
Working in Mac OS.
You used the Forum for Digital Edition. Better you repeat the quesiton in forum for Premiere pro or After Effects.
You merely need to export in a codec which supports an alpha channel. It sounds like you don't have the right settings lined up. Are you still experiencing this issue? Let us know.
