Intel announced the Arc A770 and A750 today and quietly put the A310 specs on their website, all have AV1 hardware decoding and hardware encoding.

The new Radeon 7900 GPUs also support AV1 HW encoding. Has anyone had a chance to test the quality?

https://arstechnica.com/gadgets/2022...-with-caveats/

I've not found anything online with any details about the encoder updates.

There is a OBS sneak peek here: https://youtu.be/HAc7BKnVD6Y?t=175

OBS however not the best for source video encodes, there are missing options affecting the quality.

For those not in the know, AMD's Navi 31 RDNA3 (7900XT and 7900XTX) AV1 HW encoder supports Profile 0 and Profile 1.
That means you can transcode in AV1 4:4:4 10-bit using an encoder that isn't aomenc or rav1e now.

Rigaya tested AV1 quality 10 bit with one sample and VMAF+SSIM metrics:

https://rigaya34589.blog.fc2.com/blog-entry-1607.html

In this it's worse than Nvidia+Intel.....and slower.

Regarding AV1
Does anyone know why this encoder is not more common? it is not in any of my programs by default and as far as I know it should be able to give the same image as hevc but with almost half the size. Fantastic in my opinion, who always export everything with max quality.

Because it requires a lot more encoding efforts, will usually take longer than x265 with comparable options. And decoding is more demanding as well, so it's harder to play UHD in real time without enough CPU power or GPU support.

There actually is an interesting reason for why aside from the usual encoding speed reasons, HW decoding support(for DRM purposes) and MPEG inertia: current encoders don't have deep psycho-visual pipelines outside of a few specific cases.

That means you can't use AV1 encoders to completely replace all use cases of previous most used encoders(x264, x265).
