Alpha transparency in VideoFile module

[doleo]

I've got some transparent (alpha channel) HEVC videos that I'm trying to use. They appear transparent in other software, but they're not transparent when I load them in the VideoFile module.

Anyone know what I'm doing wrong? Thanks!

The VideoFile module does support some codecs with alpha, but maybe not HEVC.

Ok, anyone know a codec in particular that works? Animated PNG files don't work properly, either. They take a very long time to reset to the 1st frame, while looping.

By far the most efficient codec to use in the VideoFile module is Hap, which has an Alpha option. https://hap.video/using-hap.html

I got it to work with the Voukoder Plugin and then exporting from Davinci Resolve direct as HAP.

That really brings me to my limits right now. I have a masked video in Davinci Resolve and now want to export ist with Alpha Channel to use it in MagicMV.
Testet several Formats, but nothing works for me...

DNxHR HQ --> big file and MagivMV does not have the Alpha Channel
DNxHR 44 12-bit --> super big file and crashes MagicMV
AVI Grass Valey --> is super slow and has some kind of green Alpha Layer not completely transparent
GoPro CineForm --> nice file size but invalid format for MagicMV

Would appreciate it enormously if someone could show me a useful workflow? (i use Windows)
