Then it might be quite a nice alternative all GPU enc/dec.
I'm curious if it would rank higher than ProRes. Would be interesting to try to match ProRes HQ bitrate with lossy H264 all I frames and compute visual scores for both. I'm not aware of a GPU supporting lossless for decoding. No issues with fast cuts or fast forward / reverse playback JKL.
ProRes is smoother to scrub with the mouse, but H264 is good enough for me. It should be slower than ProRes, DNxHR (maybe it's GPU decoded).H264 4:2:0 8bit 4k60p lossless all I frames uses about 56% CPU when looping the timeline, ProRes HQ 4:2:2 10bit about 51%.
