To add: some of the "magic" of AV1 is the grain analysis and synthesis. This allows you to get good results at lower bitrates, in particular with grainy footage, because you aren't storing the grain the classical sense -- you synthesize it when playing back the file, using a profile generated during encoding.

But if this is really "good" or not is a matter of opinion. By definition you are storing less data than on, say, H265, so it's a bit of a cheat. Personally I like the results. Encode times are still bad of course, but that will be less of an issue as time goes on.

Unfortunately AV1 encodes simply take too long for me at the 1/2 preset (equivalent to very slow) with a 8c/16t CPU.

I will probably give it another go on my next build (was planning an update to Zen6, but considering the price situation, I will have to wait another 2-3 years). And honestly my 5800X/3080 system is doing fine.

There are multiple AV1 encoders. SVT-AV1 was at least as fast as HEVC for the same quality/bitrate last time I tried.

That's the one I used albeit it was older version even when I tried it in early 2025.

I always use the lowest "quality preset" (e.g. "slow", "VerySlow" in x264/x265). The equivalent present in SVT-AV1 will was a number value (I believe 0 = placebo in x265/x264, I went 1/2).

Unless there have been massive improvements in SVT-AV1 in the last 12 months, you most likely get much longer encode time if you go with lowest quality preset equivalent in SVT-AV1.

Maybe I am missing something? Genuinely curious as I don't have much experience with SVT-AV1 (I've done several hundreds of encodes of different levels of complexity with Xvid, x264, x265 over the past ~20 years).
