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.
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:
> It’s a multi-decade, billion-dollar street fight over bytes and pixels, waged in the esoteric battlegrounds of DCT blocks and entropy coding
LLMs tend to produce ridiculous similes, idioms, euphemisms, and analogues that fall apart upon the slightest scrutiny, as though they are genuine English constructions. I despise it. No one in reality writes like that. Who the hell thinks 'bytes and pixels' are a battleground? if you want to talk about licensing problems, just say they are licensing problems, don't accept shitty similes from LLMs that humanise decidedly non-human constructs. More so if it's a technical discussion: just get to the bloody point.
I like using real idioms that have percolated through culture ('birds of a feather', 'white elephant', 'nip in the bud', etc), not stupid contrivations.
As someone who sweated through hours and hours of English essay-writing in school, LLM output that is misrepresented as genuine human writing is annoying and highly disrespectful of the reader's time and effort.
The moment I saw the stupid, contrived headers and dozens of emojis, I closed the tab.
I refuse to waste my time reading the output of a matrix multiplication done in some server farm when I could do the latter myself.
Well, journalists often write like that. I presume that's where the LLMs learned. I always find that style annoying, but especially so in a technical post like this.
This didn't trip my AI detector; I instinctively skimmed to look at the numbers and conclusions. Your comment made me go back up to the top and read the opening paragraphs and I see what you are saying. It is always painful to realize you are reading AI product. I think it is less of a problem with this blog post because it is just presenting a handful of tables of numbers and a few graphs, but it seems I am already unconsciously training myself to ignore florid AI writing.
Well, use the chatgpt-based compression system for this articl about compression.
By that I mean they might have used ChatGPT to expand this article from simple bullet points and now you can use ChatGPT to summarize this article into succint bullet points for quick digestion.
I would 100000% rather read the author's own writing even if English is their 10th language
Rather than this inflated slop that look like I am trying to reach word count in a paper and one sentence becomes 15 useless ones
Edit: This is not so much commentary on AI than it is the core of your post is a few tables. Just post the tables and one or two sentence of conclusion and that is all ! It is so tedious to read through dozens of paragraph of autogenerated unnecessary nonsense -- that contribute nothing of value to the data
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.
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.
I agree that this text in its current style is very hard to read. Feels like the text was ballooned up to 3 or 4 times its original length with pointless "side content"? Lots of distracting noise basically. AI or not AI, this is not very good.
… and so I'll continue to stick with AVC, thanks! :-)
Came to say pretty much the same thing. This slop is unreadable for me at this point.
I keep getting a paragraph or two into something, read one of the terrible "It's not just word - it's massive hyperbole!" sentences, see that there are several more in subsequent paragraphs and can't continue.
However bad the author's original writing that generate this output was, it can't be as awful as this.
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?
Taking screenshot of netflix on my device results in black square, I dont know if this applies on lower levels of Widevine but if it doesn't then the quality will be much lower as Netflix do not serve 720+ video unless there is protected DRM path
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.
> 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.
As someone who tried Roku, Android TV, and Fire TV before switching, better hardware offers a vastly better experience. The Apple TV's hardware is fast. The UI doesn't lag. Things feel smooth as butter. Yes, maybe the Apple TV doesn't need more, but more can be helpful.
In terms of AV1 support, YouTube often only does 4K with AV1 so that's an issue for people.
Personally, I'd love to see an Apple TV that was great for gaming. New Apple processors have hardware ray tracing and decent gaming performance.
I think it's also likely that Apple will try and make an Apple TV that will support next-gen Siri and on-device AI stuff. Yes, you can complain about Apple's AI delays, but Apple's probably looking toward an Apple TV that can support their AI models.
In some ways, "what benefit would a new <insert-thing> have?" Sometimes we don't know until we have it and people start using it.
Apple just hasn't been able to get traction with gaming on Apple TV. Gaming on Apple TV is so small I couldn't even find an analyst report breaking down the market size.
I don't think new graphics hardware solves the problem. Beyond the friction of the unit not shipping with a controller, tvOS lacks good discovery for games and there is no ad infrastructure comparable to mobile. Most game developers aren't looking to invest in small, closed platforms with bad discovery. It's hard enough to make money on Apple's mobile platforms.
I wouldn't mind if they enabled the 120 Hz support with the new chipset. I like my TV but the framerate matching feature causes a few seconds of black screen each time I switch between and also drops the UI to 24 FPS. Would be nice if everything just ran at 120 FPS all the time, and since 24/30/60 are perfect frame multiples that's nice to. NTSTC content at 23.976 I'd hope the player would just speed up at that point, but even if not... judder at 120 Hz is better than at 60 Hz.
Also 6 GHz Wi-Fi would be nice. I had to run a cable to my 2 because the 5 GHz airspace where I am is too crowded to stream high quality movies via Infuse without occasional hitching. Same with the seek speed. Meanwhile my iPhone gets 2.9 Gbps of goodput at solid jitter on 6 GHz Wi-Fi.
There's probably some updates to the HDR standards. For me at least though the current one already supports what my TV does.
Also apps seem to assume "because hardware decode isn't available don't serve AV1" sometimes. As silly as that is with the CPU power in the AppleTV, at least that problem would go away with hardware support and they'd stop trying to serve a "compatible" SDR h.264 stream. Despite internet pessimism, sometimes the quality is also raised with more efficient codecs rather than just "the same quality at less bandwidth".
> Also apps seem to assume "because hardware decode isn't available don't serve AV1" sometimes.
This isn't a completely unreasonable decision, since the current 2022 model's software AV1 decode apparently can only sustain 4K AV1 decode (although it handled 1080p content fine in my test) for as little as 45 minutes before thermal throttling kicks in.
Some content is truly exactly 24 FPS or 30 FPS though, so whichever path the TV goes (i.e. NTSC rate or integer rate) the same problem will exist. I suppose some TVs might have extremely fancy film mode detection which catches the occasional frame difference, but I doubt mine does :D
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.
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.
The credible rumors beyond AV1 decode include: Wi-Fi 7 via Apple's home-grown N1 chip, a CPU fast enough to support the next-gen Siri release on-device, a RAM bump, improved pass-through for high-end audio formats, potentially a camera (the new square selfie sensor would be perfect for this) for easier group/family FaceTiming, and more aggressive pricing.
Was 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.
Very good read, love some of the humor in this article. It helped me get through to the end!!
Also, If anyone was wondering where AV1 stands in comparison to VP8 and VP9... I just looked it up after a few years of not paying attention and I guess Google donated VP8 and VP9 to the alliance for open media foundation (AOMedia) in 2015 and they created AV1 and released it in 2018.
Yeah, AV1 is primarily based on what Google was working on for their own successor to VP9, what would have been VP10, with technology contributions from Mozilla/Xiph's Daala and Cisco's Thor codecs.
Not doubting your experience, but I can't see a single ad using Safari on iPhone.
I was really impressed with my setup, but after disabling content blockers (Firefox Focus), and turning off using Mullvad's free DNS proxy service, still nothing!
Perhaps the author turned the ads off since you visited?
Okay, so AV1 has lower bitrate. I can encode any video format at arbitrary bitrates, but that metric is not useful on its own. An article about how AV1 requires less bits for the same or improved perceptual quality would have been far more interesting.
> Device Support: Hardware decoding for AV1 isn’t on every device yet.
By now - it should be in most devices that's aren't outdated by even average standards. And it's worth mentioning that for devices that don't have hardware decoding, dav1d does an excellent job of decoding it on the CPU.
The problem is more with hardware encoding. That's indeed only present in only recent generations (or a couple) of hardware and even with that, AMD for example have an aspect ratio limitation bug in their AV1 hardware encoder (which requires adding black bands to work around) that's only fixed in RDNA 4 which is not available in their APUs, so it won't be fixed in APUs until their UDNA is used for them (they didn't fix it in RDNA 3.5 chips).
One of the quite expensive paid plans, as the free one has to have "Created with Datawrapper" attribution at the bottom. I would guess they've vibe-coded their way to a premium version without paying, as the alternative is definitely outside individual people's budgets (>$500/month).
Inspecting the page, I can see some classes "dw-chart" so I looked it up and got to this: https://www.datawrapper.de/charts. Looks a bit different on the page, but I think that's it.
