Alpha transparency in VideoFile module

Post by 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

[Update]
:o 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)
