HEVC video with Alpha channel in Compressor
There used to be a feature in Compressor when encoding video into HEVC codec, that allowed you to click a box to enable an 'Alpha Channel' as supported by the H.265/HEVC spec...
What happened to that checkbox in the latest 4.4.x versions of Compressor ?
Here is a screenshot of an earlier version of Compressor:
I'm trying to use a ProRes 4444 video file with an alpha channel as source and export as an H.265/HEVC file with the alpha channel intact and cannot find a method to do so any longer with new Compressor version.
