Anyone use AV1? How good is it? What are your thoughts on AV2?
I manually turn AV1 off on my android phone. It uses more battery and won't sustain 1440p at 1.5x speed up without the odd frameskip.

#22Anyone use AV1? How good is it? What are your thoughts on AV2?
I did some testing with the 3 main AV1 encoders with gifs (avif). They’re pretty good. But not as good as jpeg xl but currently basically only Safari supports it.
See my blog: https://catskull.net/libaom-vs-svtav1-vs-rav1e-2025.html
For most “normie” use cases, I’d recommend cloudflares image transforms which are available on free tier. I actually wrote a small Jekyll plugin for my site to auto prefix images with their transform. Idk why but shipping optimized images is just one of those things that tickles me!

#23Is this intended to be competitive with h.266/VVC? And is it?

Yes:
> VVC is not alone in the video coding race. AV1, backed by AOMedia, has already gained traction, although its performance does not make it a direct competitor to VVC in high-end applications. The upcoming AV2, as well as AI-driven encoding techniques, could pose challenges to VVC’s success. Nevertheless, VVC’s strong technical foundation, industry support, and clear intellectual property structure position it as a promising long-term solution for video coding.

> For businesses focused on reducing operational costs, this is a key point in the h.266 vs av1 debate. While the H.266/VVC codec offers powerful compression improvements over h.265, AV1—and eventually AV2—may be more attractive thanks to simpler licensing and long-term affordability.

Encoder are extremely slow.
SVT-AV1 is the fastest software encoder for pretty much any level of quality you would want.

I use AV1, it is very efficent

#27This might be a response to H.266/VVC, which was finalized in 2020 but apparently saw limited adoption so far: https://en.wikipedia.org/wiki/Versatile_Video_Coding

#28"AV1 adoption is accelerating" But before it is widely used and accepted, here's AV2 for you to have compatibility issues with in the wild With the ubiquity of h.264 and the patents expiring, will anyone but streamers care?
h266 (aka VVC) is seemingly ~~late in development~~ (edit: It has been released but doesn't have much hardware uptake yet). They probably want to ensure that people are aware that it will be matched so that they don't commit to it and AV2 ends up a bit late to the party like AV1 is compared to h265 where it had a notable compatibility lead.
If people know that AV2 is coming and competitive they may avoid adopting h266 and wait for the open alternative to ship.

#29The tech was surely locked down long ago if they're close to announcing, but just putting the dream out there that AV2 makes next-gen image compression more practical. AVIF's very effective at maintaining OK quality at low bitrates, but encoding at high quality on CPU (something like the common ~2bpp JPEG) was very slow. I think that slowed down adoption and was one of the reasons JXL still had a niche. Progressive mode would help for images too.
Another great thing JXL has is lossless recompression of .jpg files, which is a smaller improvement than a whole new format, but much easier to deploy. Saving 22% beats saving 0%. Harder, of course, to see how that one would connect to any of AOMedia's other priorities.

#30It would be great if AV1 was as ubiquitous as H.264. Apple is very much holding things back by insisting that Safari only support AV1 on devices with hardware decoding (M3 and higher), even though other browsers use software decoding just fine.
(Safari has a low market share but I have an above-average number of Mac / Safari users using my site)
