That seems like a gimmick and I actually prefer SDR video that is not upscaled. There is something ugly about those AI treated videos. They look fake.

They are fake. Ultimately it’s not recovering lost detail, it’s making shit up

Exactly. This is akin to upscaling or frame rate interpolation. No consumers want this, they turn it off in settings.

That's my point -- most people don't actually watch the movie at home. That's why 3D TV failed.

I don't think that's why. TVs without 3D are just cheaper, the early 3D tech just wasn't very good and took awhile to mature thus souring the market, 3D content was more expensive (or an extra expense, eg. buy the 3D and non-3D versions of a movie) and so people just went for the cheaper options overall. I've had an active 3D TV for 10+ years, and the 3D has not itself been a problem when I've watched with others.

The only time it's a problem is if someone currently experience a migraine is trying to watch, then they can get serious vertigo, but that's an issue caused by the migraine itself (visual auras and vertigo generally).

A lot of people wrote it off as unnecessary gimmick, I'd add that to list of reasons. VR 3D blows it out of water but then requires more effort to use.

My parents had a 3D TV. It was a huge problem. You probably don't realize how often you look away from your TV when you're watching your TV.

While watching a movie, look away - maybe. Get up and walk around and do chores - we always pause if needed. I think it's a matter of establishing that to watch a movie, one needs to set aside time and commit to focus just on it, but then it becomes yet another barrier. Different story for TV shows which often are background though.

Yeah that's my point -- most people don't watch movies at home that way. They are just background distractions, even movies.

All of those reasons certainly contributed, but the reality is that most people don't watch movies at home the way they watch in a theater, where they dedicate 2+ hours to the experience with no distractions.

I do that, but I have to wait for everyone to go to bed first and then turn off my cell phone. Most people aren't willing to do that.

I'm curious - what's the best open-source video upscaling library out there? I looked back about a year ago, and it didn't seem like there were any good open-source solutions.

It depends on what do you mean by 'open-source', along with training materials and full setup? That will be hard to find. Upscaling was popular like 10 years back. That's why there is no much interest today. Training in old style isn't that hard. But artifacts are popping up in all videos I've seen.

This stuff is sick. If we had a real-time upscaler on a zoom telescope it would be a fantastic tool while traveling. I'd get a kick out of that.

And what would fake detail in the real world give to you?

I can pretty easily distinguish useful LLM output from non-useful LLM output though others on this website seem to have lots of trouble. I think I can pretty easily do the same for things in the visual field. To be honest, part of why I'm successful is that I can draw use out of imperfect tools.

Speaking of which, Nvidia has built-in live AI upscaling on the Shield TV android box. - Is there any stand-alone live AI upscaling / 'enhance' alternative for android or any other platform?

The Shield is kind of an extreme outlier in today's environment. A device from 2015 that 9 years later is still one of the top tier choices in its (consumer) market is almost unheard of.

In fact it's reportedly the currently supported Android device out there with the longest support[0], it's crazy that mine still gets updates.

Traveling to a real destination so that you can look at fake AI generated crap on a screen instead of the actual surroundings.

A bit of a let down that the video demoing SDR->HDR conversion is itself only published in SDR. Makes as much sense as demoing a colorization tool in a grayscale video!

If they were serious about showing this tech off they should've provided a video file download. Also indicate that it's a HDR file and should only be viewed on a HDR display. Youtube is just making this look bad as people won't see a difference.
