2.6.4 AV1 Intel Hardware Encoding

General Support / Questions Hardware Encoding

Not really a question, just wanted to mention that I tried 2.6.4 but the AV1 quality isn’t great with Intel Arc hardware at least with the given settings.

We spoke about 2.6.3 beta and you provided the following settings I put in my profiles.conf AV1 settings and they give much better video quality in 2.6.4 as well (though slightly bigger files)

ffmpeg-video=-ss 0 -vf yadif=0:-1:1,hqdn3d -vcodec libsvtav1 -preset 6 -crf 32 -map 0:v -sn

handbrake-video=–start-at duration:0 -e svt_av1 --encoder-preset 6 -q 32

Great feedback, this is good reference for other users.

We reduced the default crf from 32 to 37 because it was generating very large files when using the software encoder. I guess the hardware encoder quality (intel) isn’t as good so you need a higher crf to achieve a similar quality. A suggestion, if you’re using hardware encoding, rather than changing the default profile parameters (which will get reset each time you upgrade MCEBuddy), try to move the quality slider (like make it +30%) which has the same effect (it will increase the crf) but now the conversion task settings will carry over through each upgrade as it doesn’t depend on the default profile values.

Ok thanks. I’ve been doing some quick tries between +20 and +30 and seems pretty decent - just trying to figure out my preferred file size vs quality.
