Fascinating, 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.

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 bitr…

Ditto. Between AV1's momentum and the imminent release of AV2, it sure feels like VVC will find limited adoption outside of broadcast applications.

It's unfortunate because there's plenty of good, technical, perfectly readable content in the author's blog archive from 2021 and earlier without the overwrought purple prose. https://singhkays.com/archives/

I wonder why there is 4 year gap there. Their English is not even bad ! Its better than mine and definitely does not need any kind of GPT copyediting

I 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.

I definitely appreciate the concise nature of the article. Doesn't waste my time at all. Whether that's due to the authors writing ability or some summery tool, I could care less.

Interesting charts, but this is all completely meaningless without image quality comparisons. I can easily use 50% less bandwidth than Netflix's H264 streams as well, with H264 even, by just cranking up the compression & dropping the bitrate.

Presumably nothing jumped out at the author as being worse, but come on how can you have a whole section on why AV1's regression on Bojack is actually a good thing because the quality is way higher, and then not show any quality comparisons?

Intolerably ChatGPT-esque. Which is a shame, it seems like a nifty little DIY experiment.

I think what stands out to me is this cartoonishly punchy, faux-dramatic framing.

That, and specialist terms that seem to be thrown in there in an empty way, just to signal subject-matter expertise that’s not even expected of a DIYer’s experiment report:
