It would not make any sense for them to be upscaled on the fly. It's a computationally intensive operation, and storage space is cheap. Is there any evidence of it being done on the fly?
It would if they can do it on your device.
While it could theoretically be done on device, it would require the device to have dedicated hardware that is capable of doing the processing, so it would only work on a limited number of devices. It would be pretty easy to test this if a known modified video were available.
AI upscaling can be run on a ton of devices nowadays.
Also people are forgetting it’s not just storage, it’s bandwidth they save with this move. So even if they store both the low and high res copies they can save 4x the bandwidth (or more) serving to devices with upscaling capabilities.
That would depend entirely on WHAT its doing. I have not personally seen any of these videos yet, but based on what was described in the article, I would imagine that a typical CPU would not be able to handle it.
It’s not that computationally intensive to upscale frames. TVs have been doing it algorithmically for ages and looking good doing it. Hell, nVidia graphics cards can do it for every single frame of high end games with DLSS. Calling it “AI” because the type of algorithm it’s using is just cashing in on the buzzword.
(Unless I’m misunderstanding what’s going on.)
You are right that nvidia cards can do it for games using DLSS. Nvidia also has a version called RTX video that works for video. But are they could to be dedicating hardware for playback every single time a user requests to play a short? That is significantly different than just serving a file to the viewer. If they had all of these Nvidia cards laying around, they surely have better things that they could use them for. To be clear here, the ONLY thing I am taking issue with is a comment that it seems that youtube may be upscaling videos on the fly (as opposed to upscaling them once when they are uploaded, and then serving that file 1 million times). I'm simply saying that it makes a hell of a lot more sense any day of the week to upscale a file one time than to upscale it 1 million times.
My video card deffo heats up more when watching youtube over peertube. I'm pretty sure they're using my graphics card for upscaling.
