I hope the future is bright with AV1. But even scene groups heavily release in 265 instead of AV1. Hardware support is going to get better over the years and hopefully everyone will just use AV1 and leave this license BS behind.

I believe this is because scene groups don't really care about patent licensing, and there's around 5-6 years of computers with hardware H.265 decoding and no hardware AV1 decoding. I think we'll see AV1 and successors take over in 5-10 years when it's safer to assume users will have AV1 decoding.

I bought an Intel Arc A580 and then later B580 which also has an AV1 hardware encoder, and I have to say that it's really pleasant, good enough for real time streaming, video recording even at lower bitrates (e.g. 1080p30 at ~10 Mbps is okay) and ends up saving a lot of space when compared to both H264 and H265, which previously wasn't viable because the CPU based encoder is painfully slow.

I saved a few hundred GB of space by re-encoding all of my local videos in AV1, I'm guessing it might be have been one of the better cases because most of the videos were anime instead of more detailed video like regular movies, but it worked out nicely for me! Plus, the software support is also quite good: OBS and Handbrake had no issues, neither does VLC seem to have any.

All of that makes me wish it'd become more widespread in the next decade or so, everywhere from YouTube and Twitch to even our phone cameras.

FWIW Most Streaming TV Services like Zattoo do 1080p50 using H264 using that Bitrate and while not perfect it's fine - using AV1 one could probably go way below that.

1080p30 at ~10 Mbps isn't a low bitrate unless you are aiming for something very specific. Not to mention there is H.265 hardware encoder inside Intel Arc, although I have no idea about their quality. Nvidia seems to do a much better job in this area.

I'll continue to use h264 because it has hardware acceleration on my Thinkpad X220, whereas x265 doesn't enjoy the same luxuries on this laptop.

It might be time to consider some new hardware. That machine is going on 15 years old now!

AV1 is extremely slow to encode last time I tried.

i80and|11 months ago

My guess is you were using the reference AOM encoder. This is actually a real branding problem! It was never designed for encoding speed, and it shows.

SVT-AV1 is the production encoder you should be using. It's high quality and fast in software, and should really always be the default.

spongebobstoes|11 months ago

For now most of the focus has been on the slow encodes, but in theory it can match h264 for speed and quality on encoding. In practice I've seen it get very close already.

ksec|11 months ago

Because scene groups are still done by enthusiast that actually cares about encoding quality rather than patents licensing.

vp9 is widely used (e.g. YouTube is mostly vp9, av1 and fallback h264) and not much worse

I avoid AV1 sources for anything I care about, because of film grain synthesis.

p1mrx|11 months ago

Does AV1 just emulate the film grain from the source video, or are people adding/customizing the grain when encoding?

Latty|11 months ago

Why? It's a feature you have to explicitly turn on when encoding, and I've not seen people using it for most stuff.

including digital footage with film grain added in post?
