> I’ve never tried to encode NDI. I think it is YUV inherently. H264 should be no problem on cpu. For UHD 12bit RGB444 CPU is hard but can be done. Lots of things for you to test and play with.

Yes, it’s 422 YUV from Flame. Works just fine. Tested with EC2, Apple Silicon and Threadripper encoders on Rocky9/MacOS with ProRes, H265 and H264.
