On a related note, why are release groups not putting out AV1 WEB-DLs? Most 4K stuff is h265 now but if AV1 is supplied without re-encoding surely that would be better?

I looked into this before, and the short answer is that release groups would be allowed to release in AV1, but the market seems to prefer H264 and H265 because of compatibility and release speed. Encoding AV1 to an archival quality takes too long, reduces playback compatibility, and doesn't save that much space.

There also are no scene rules for AV1, only for H265 [1]

> Encoding AV1 to an archival quality takes too long

With the SVT-AV1 encoder you can achieve better quality in less time versus the x265 encoder. You just have to use the right presets. See the encoding results section:

Yeah, is there any good(and simple)guide for SVT-AV1 settings? I tried to convert many of my stuff to it but you really need to put a lot of time to figure out the correct settings for your media, and it becomes more difficult if your media is in mixed formats, encodings etc.

I do a lot of AV1 encoding. Here's a couple of guides for encoding with SVT-AV1 from enthusiast encoding groups:
