No vulkan render formats have been added. I do not have the hardware to test either (I really need a new kick-axx computer!) But because you have Andrey's package installed, maybe you test yourself (only not sure about the first line):
1. cd <wherever the package is installed>/bin/ffmpeg/video 2. cp hevc_vaapi_10b420.mp4 hevc_vulkan_10b420.mp4 3. edit hevc_vulkan_10b420.mp4 and change the first line from "mp4 hevc_vaapi" to "mp4 hevc_vulkan". 4. restart CinGGG

I have the latest CinGG-20251231-x86_64.AppImage and cinelerra-5.1-20260106.susetw.x86_64.rpm installed on openSUSE Tw-Slowroll.
Shift-Render and Video-Wrench Compression list the previous vaapi and qsv hwaccel methods.
Shouldn't we also see a base Vulkan tag here to start experimenting with presets?
