#2Fascinating, thank you for this analysis! Currently pining for release of an updated Apple TV, which will have an SoC capable of hardware AV1 decode.
It'd be great to hear from someone at Netflix about the unexpected Bojack Horseman results. I'd bet that Netflix just isn't yet taking advantage of AV1 features designed especially for this kind of animation and synthetic content.

What benefit would a new appleTV have other than reduced bandwidth usage?

#4I feel like this was copy edited by ChatGPT and it really grates me. I couldn’t help but lose focus after I started seeing telltale signs of AI.
While the topic matter is interesting, I feel like obviously synthetic content falls into the “that which was not worth writing, is not worth reading either” trap.
If the authors tone is extremely ChatGPT-esque, I apologize in advance.

> the unexpected Bojack Horseman results. I'd bet that Netflix just isn't yet taking advantage of AV1 features designed especially for this kind of animation and synthetic content.
While the percentages look scary, it's only a slight difference (60kbps!) and still around 1mbps average, but with a significant quality boost (very crisp lines and near perfect quality). I bet Netflix could encode at nearly half that bitrate and stay similar to HEVC in quality, but I'm pleased they seem to have made a good tradeoff here.
It's actually quite amazing the quality that AV1 delivers at such low bitrates across the board. I've said it before, but AV1 is almost magical. Which I think is behind the lack of enthusiasm for VVC/h266; is anyone even using that? I've yet to actually see it in the wild.

It's the emoji bullet points and headers that makes me instantly close a page.

The Bojack example shows that it's not just reduced bandwidth; in some cases you can get higher quality with their AV1 encodes. Additionally if you are thinking of average bitrate, that's ignoring variable bitrates (and the extension, the per-shot encoding params that Netflix utilizes.) That is to say, high complexity scenes get more bitrate than low complexity, so very noisy scenes can look way better using AV1 even while still using lower bitrates, but notably some peaks have similar max bitrates.

#9Was once out in a remote area on an 800 kbps DSL connection. YouTube couldn't stream, Prime Video couldn't stream. Netflix worked fine. Years later, I remain impressed at their uniqueness.

The promise of new codecs is reduced bandwidth and higher quality. Probably a new device also has a faster processor and/or more ram in general, which helps with incidental jank. Apple TVs are well regarded and maybe have less jank than other products (I don't have personal experience, I'm interested, but my Apple computer is a IIe so I expect account management issues), but it's nice to get a new Roku every once in a while as bloat/jank seems to creep up on them.
