This is a very important update and something that opens a considerable amount of doors for developers.

Not to rain on your parade… but alpha support’s actually been there since day 1 of HEVC in macOS. Merely full *playback* support is new on certain OSs/apps. ????
But yeah, too few people know about this.

I have never ever seen any hint of alpha level support inside H265 codec when encoding with either Adobe Media Encoder, Resolve, After Effects, FCPX or Motion.
Is there a current compressor preset that you can link me to so I can see this in action please?
Every time I use h265, the option to export alpha channel data along with the RGB channels, this checkbox is greyed out.

It’s there for me for any of the HEVC presets. ????????♂️
I’d post a screenshot, but everything is apparently all screwed up here. Half the links don’t work (like the one to this thread) including the one for uploading images. Sorry.
EDIT: AH! as HTML apparently it’s fine. ????

I’ve done several encoding tests of H265 with alpha, either directly with the finder or via compressor and I have strange alpha display when embedded on a webpage. does anything have seen that before ?
