Also, it’s not the whole picture. AV1 is open because it didn’t have the good stuff (newly patented things) and as such I also wouldn’t say it’s the most modern

Just because something is patented doesn't necessarily mean its good. I think head to head comparisons matter more. (Admittedly i dont know how av1 holds up)

  Yes, but in this case, it does. AV1 is good enough that the cost of not licensing might outweigh the cost of higher bandwidth. And it sounds like Netflix agrees with that.

    I don't like newer codecs like AV1. I find them blurrier. Perhaps the bitrate is too low, but they do seem blurrier compared to h264. Even VP09 has often seemed better. h264 is a very good codec.

      they usually run newer codecs at a much lower bitrate, and do group testing to make sure the quality is "acceptable". in double blind testing, at the same bitrate, you'll pick the "new" codec every time. but yes, they're trying to save money on bandwidth. it's annoying

AV1 has plenty of good stuff. AOM (the agency that developed AV1) has a patent pool https://www.stout.com/en/insights/article/sj17-the-alliance-for-open-media https://www.stout.com/en/insights/article/sj17-the-alliance-... comprising of video hardware/software patents from Netflix, Google, Nvidia, Arm, Intel, Microsoft, Amazon and a bunch of other companies. AV1 has a bunch of patents covering it, but also has a guarantee that you're allowed to use those patents as you see fit (as long as you don't sue AOM members for violating media patents). AV1 definitely is missing some techniques patented by h264 and h265, but AV2 is coming around now that all the h264 innovations are patent free (and now that there's been another decade of research into new cutting edge techniques for it).
