Here's a preliminary look at how AMD fares with the Intel test clip, and it doesn't look too good.
Unfortunately Handbrake doesn't support open gop yet which improves the bitrate efficiency a bit. I was always under the impression that while AMD's HW H.264 encodes were kind of rubbish, H.265 was "OK". I have older Polaris Radeon/Radeon Pro WX cards with VCE 3.4 (technically Lexa, Ellesmere, and "Polaris 20" - they should differ only in encode speed, I'll double check VCEEnc's output but will most likely use the Ellesmere card) and a Radeon RX 5700 with VCN 2.0.
I flipped through a few pages and didn't see any AMD results - or any single test clip with as broad a range of encodes/settings (thank you Yups). Would I be mistaken in assuming this would be the easiest sample to provide AMD VCE results for, for comparison's sake? Once I figure out a way to streamline running multiple encodes and then testing those metrics, and have enough time to play with settings. The difference is really big, Gen9 looks much worse in the video.Īnother x265/x265 CRF vs Iris Xe CQP comparison using this () sample. For now only a PSN-Y test using this () sample, all of them HEVC main x1080 at ~2.5 Mbit 24 fps/240 gop. On Intel both HD630 and Iris Xe the constant bitrate modes seem to work a lot better with a low bitrate budget.

Is it important? How to enable FF encoding properly? I have noticed -fixed-func sets QP Limit min: 10 when EU encoding mode sets QP Limit min: 1.
