Magic Music Visuals

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]
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)

I had the same issue on my Mac. After trying many various HAP decoders, only one did the job. I think it's because all these are outdated and/or maybe not compatible wit a Silicon Mac. The one that works is a plugin for Premiere Pro called AfterCodecs from Autokroma. But it only works for HAP Alpha and not for HAP Q Alpha. When opening a file exported with HAP Q Alpha, MagicMV gives an 'invalid file' error. The AfterCodecs is a payed plugin (about 100 euro), but it is free when using up to 500 frames. For the time being that's just enough for me.

It turns out that the free 500 frames from AfterCodecs is not enough for me. So I searched further and found that Premiere Pro 2025 (yes they are ahead of their time ), does offer export of a video with alpha channel that MMV does accept. This YT explains it: https://www.youtube.com/watch?v=-eGBrC50wcY. So this is the solution IF you have Premiere Pro. Hopefully other video editors do offer the same option like, as mentioned earlier, Davinci Resolve. BTW I'm on a Mac, so maybe for Windows it is (completely) different.
