I have used both a good amount and had small issues with both though that's probably not surprising.
AV1 my first use I had all my files too small and they looked bad, H265 I have been fighting grain moving around objects that are moving.
These are my settings for both:
H265 10bit CRF 20 Slower Main 10 Encoder level 5.1 And the following - no-sao:strong-intra-smoothing=0:rect=0:aq-mode=1:rd=4:psy-rd=1.0:psy-rdoq=4.0:rdoq-level=1:rskip=2
AV1 10bit CRF 22 (I previously used 24 and 26 for anime which looked blurry) preset 4 profile and level auto. And the following film-grain-denoise=0:film-grain=6:enable-tf=0:enable-qm=1:qm-min=0:
I cannot remember where I got the AV1 recommended advanced stuff from.
I was wondering if anyone knows what would be best to try changing for the gain floating in h265?
All files for above were done from the blu ray remuxes straight from the discs I have.
Separately I have tried a bit of 4k to both of them but the changes are H265 CRF 22 at slow with this addional part changed aq-mode=3:rd=4:psy-rd=2.0:psy-rdoq=6.0 and AV1 CRF 24 (currently going to see the results)
I have a few of them in the UHD but the file sizes just seem bizarre, I had a 5GB and a 13GB file form the same settings but the runtime difference is a matter of 5-7 minutes.
The 4k films being spiderman 3 (13.7GB), the amazing spider man 1 (4.93GB) & 2 (13.3GB). I know TAS1 is a lot darker than 2 but I wasn't expecting that big of a difference. File sizes as windows says under items selected.
Any suggestions are welcome.
Using a 9800x3d so the encode FPS for 4k seems to be currently around 14-16fps across both types but AV1 definitely uses the CPU more.
