I have tryed to upload a motion footage with alpha channel, it was encoded in quicktime PNG with alpha channel, and it got rejected as it is no longer supported. I tryed making that footage with alpha channel with Apple ProRes 4444 codec, but got no success because im on windows? Where are no Apple ProRes codec in after effects. I tryed to use video encoder program to convert to Apple ProRes but the alpha channel dissapears.
How do you make footage with alpha channel to upload to videohive? I dont have mac.
