Modern codecs like AV1 can bring better quality video to the open web
I've been using a lot of H.265 (aka x265/HEVC); some pirate scene TV and movie releases come out in it. It's fantastic. About 1/3-1/4 the size of H.264, which makes a huge difference both with download and with archiving. The downside is that there's not a lot of hardware support for encoding or decoding. Doing it on the CPU isn't bad but definitely not as energy efficient.The problem with H.265 is the IP situation is a mess. AV1 looks to be better in every way. Looking forward to its adoption. So far the pirate scene doesn't seem to be using it at all.
