Requested feature overview description.
AV1 is a royalty free video codec that compresses 30% more than VP9 at the same quality.
Why would it be useful?
The codec would reduce video file sizes compared to VP9, wich is good for users with slow connections or data caps. It will also allow to upload longer videos within the size limit at a reasonable quality.
What part(s) of the site page(s) are affected?
Server side scripts (i guess).

Bump.

It's more common than it was 2 years ago. Now you can get hardware decode support cheaply with Amazon Fire TV Stick 4K Max, Tiger Lake laptops, etc.

Useful website thingy

Looks like 75% of the market has support to it. And apple still pretends it doesn't exist.

That is by browser support, not the presence of hardware decode support.

Although if the computer is fast and the video isn't 4K or something, it might be fine.

Oh yeah, you are right.
By the way, a possible AV1 support would also mean AVIF support?

It has been discussed.

I think the real problem is that artists don't use it and have no reason to. Why add support for something on e621 when the sites where most of the artists are don't support it. They should probably be saving all of their work as lossless PNGs anyway. A typical hard drive could fit 1 million or more such images.

AVIF does have a lossless option, but I see some debate about how it works: https://github.com/AOMediaCodec/av1-avif/issues/111

JPEG XL is faster and has more features. Very few people have taken AVIF seriously.

Will it be implemented?

Name 5 artists using JPEG XL. Same problem as AVIF.

I think AV1 will be supported eventually, since YouTube rips could be AV1 and more videos could be squeezed under the 100 MB limit.

Most video decoding hardware now support AV1 including decoders from Intel, AMD, Nvidia, and various mobile SoCs. Supporting it on E6 would allow higher quality Youtube rips to be uploaded.

YT rips suffer from the same problem as Twitter, Tumblr, and so on - they are recompressed very aggressively. Irony: Artists uploading here have to reduce quality to get it within 100MB limit. Some will post a normal resolution here, and then have offsite link to Mega.NZ or the like for a 450MB monster.

AV1 is apparently already supported and that line of code has been there for a year already, interestingly it seems to originate from a commit 5 years ago (obviously that's way older than this thread) so it really leaves me to wonder whether this is actually working or not.

Has anybody posting here actually attempted to upload an AV1 file?

I'll try it in a bit, if I can find one.

OK, it's still filtered by extension.

It needs to be remuxed into a webm container, and the audio converted.

ffmpeg -i spbtv_sample_bipbop_av1_960x540_25fps.mp4  -c:v copy -c:a libopus spbtv_sample_bipbop_av1_960x540_25fps.webm

(FWIW, the video doesn't play in my browser, Pale Moon v33.1)

I think Mairo might've, but it also could've been a joke

I thought I'd add some input. I'm on an 8 year old computer with a Ryzen 1700. I don't have HW accelerated decoding on my GPU, and as a result of Discord allowing AV1 streaming, if a friend choses 1440p, I lose 25% of my CPU. If they stream in 4K, my CPU reaches 50% and my desktop becomes stutter. Until faster decoders are made, resolution limits are in place, or HW decoding is massively widespread, allowing them on E6 could cripple older devices or outright crash older phones.

Yeah, this is why a lot of places have downsampled versions.
