Who does this benefit? Sounds like this stuff mainly benefits streaming providers and not users. We get to go through the whole rigamarole again where hardware is made obsolete because it doesn't support acceleration.
Will streaming services ever stop over-compressing their content? I have a top-of-the-line 4K TV and gigabit internet, yet the compression artifacts make everything look like putty. Honestly, the best picture quality I’ve ever seen was over 20 years ago using simple digital rabbit ears. You especially notice the compression on gradients and in dark movie scenes. And yes — my TV is fully calibrated, and I’m paying for…
Kate - Netflix - 11.15 Mbps
Andor - Disney - 15.03 Mbps
Jack Ryan - Amazon - 15.02 Mbps
The Last of Us - Max - 19.96 Mbps
For All Mankind - Apple - 25.12 Mbps

Not all video streaming services choose to use the same extremely low average video bit rate used by Netflix on some of their 4k shows.

You will be made to feel the springs on the cheapest plan/mattress, and it's on purpose so you'll pay them more for something that costs them almost nothing.

Content delivery costs a lot for streaming services. After content is produced, this is basically the only remaining cost. It’s not surprising that they would go to extreme measures in reducing bitrate. That’s why, presumably, Netflix came up with the algorithm for removing camera grain and adding synthetically generated noise on the client[0], and why YouTube shorts were recently in the news for using extreme denois…

Why? ATSC is 19Mbps. A single 1080i video using that whole bitrate will look quite good.

It'd be really cool if we had 'upgradable codec FPGAs' in our machines that you could just use flash to the newest codec... but that'd probably be noticeably more expensive, and also not really in the interest of the manufacturers, who want to have reasons to sell new chips.
> FPGAs' in our machines that you could just use flash to the newest codec They're called GPUs... They're ASICs rather than FPGAs, but it's easy to update the driver software to handle new video codecs. The difficulty is motivating GPU manufacturers to do so... They'd rather sell you a new one with newer codec support as a feature.
But often a new codec requires decoders to know how to work with new things that the fixed function hardware likely can't do.
Encoding might actually be different. If your encoder hardware can only do fixed block sizes, and can only detect some types of motion, a driver change might be able to package it up as the new codec. Probably not a lot of benefit, other than ticking a box... but might be useful sometimes. Especially if you say offload motion detection, but the new codec needs different arithmetic encoding, you'd need to use cpu (or general purpose gpu) to do the arithmetic encoding and presumably get a size saving over the old codec.

So: 1. camera manufacturers and film crews both do their best to produce a noise-free image 2. in post-production, they add fake noise to the image so it looks more "cinematic" 3. to compress better, streaming services try to remove the noise 4. to hide the insane compression and make it look even slightly natural, the decoder/player adds the noise back Anyone else finding this a bit...insane?
> 1. camera manufacturers and film crews both do their best to produce a noise-free image 2. in post-production, they add fake noise to the image so it looks more "cinematic" This is patently wrong. The rest builds up on this false premise.
1.2.: Google "how to shoot a night scene" or something like that. You'll find most advice goes something along the lines of "don't crank the ISO up, add artificial lighting to brighten shadows instead". When given a choice, you'll also find cinematographers use cameras with particularly good low-light performance for dark scenes (that's why dark scenes in Planet Earth were shot on the Sony A7 - despite the "unprofessional" form factor, it had simply the best high-ISO performance at the time)
2: Google "film grain effect". You'll find a bunch of colorists explaining why film grain is different from ISO noise and why and how you should add it artificially to your films.

There's no point having reference RTL. The point of reference software is to demonstrate the correct behaviour for people implementing production grade libraries and RTL. Having an RTL version of that wouldn't add anything - it should have identical behaviour. Providing a production grade verified RTL implementation would obviously be useful but also entire companies exist to do that and they charge a lot of money fo…
Could help people on the hobby or lower budget FPGA side. H.264/5/etc never really made it
And what hobbyist is sending off decoding chips to be fabbed? If this exists, it sounds interesting if incredibly impractical.

I’m still so surprised Disney+ degrades their content/streaming service so much. Of all the main services I’ve tried (Netflix, Prime, Hulu, HBO) Disney+ has some of the worst over-compression, lip-sync, and remembering-which-episode-is-next issues for me. Takes away from the “magic”.
