This HEVC file is glitchy in PrPro and AEfxs 2022 default importers but works fine with Influx Importer (paid 3rd party plugin) https://www.autokroma.com/Influx

Warren I don't see any alpha channel there :-( With which software can you see an alpha channel in this file ? Might be something specific to Apple and not supported by anyone else

@ Antoine:
Attached is a sample HEVC with Alpha movie that we created by rendering Apple ProRes4444 with Alpha from After Effects and then using Encode Selected Video Files in the Finder for macOS 11.6 and then choosing HEVC 2160p with Preserve Transparency enabled in the Encode Media dialog box (also attached).
For those interested in HEVC with Alpha, there's a comment on the Adobe Community Support Forums that this is under review, but there is no news as to when it might be implemented. More votes should help.

It's about time that this is supported by Adobe Media Encoder. HEVC is such an amazing codec.

Would you have such a file sample ?
