> I hope the future is bright with AV1.

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.

> 1080p30 at ~10 Mbps is okay

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.
If you record a video game, I find that anything much lower really messes with the visual quality, especially if it portrays a forest scene or something with lots of detail like snow. Admittedly, you have to zoom in to notice and it's more apparent during fast movement, though VBR and other options seem to help.

The H265 encoder is also lovely, from what I've seen! Bigger file sizes, but a bit more software support in some places.
