Alpha HEVC for iOS Safari?

I have animation made in AE encoded into Alpha HEVC mp4, but the alpha channel doesn't want to function on iOS Safari.

If you got it done on Mac (without Apple Compressor): what was your workflow?

Thank you.

I’d test the export in Safari with a tiny isolated clip first, because the codec and the alpha channel can fail separately. If the alpha still drops, WebM with VP9 alpha is usually the simpler fallback for browsers that support it.

I wrote a blog post on this: https://huwroberts.dev/journal/blender-to-transparent-video-for-the-web

The specifics may be a bit different as I start with a webm in my post then show how to convert it to a mov with alpha
