So they started from a low-res scan, because film is not SD, you can do a 4K scan from film too. Of course you wouldn’t necessarily have 4K of useful information, it might just be grain. But it’s interesting to think that many of these videos probably start with subpar digitizations of the source material, and wonder what it would look like when based on a proper high resolution archival scan
- shakna 6y agoWith a lot of these techniques, you can't just start with better source material. The frames have to be resized before going through the neural net, so that they fit its expectations. So if you want to start from a 4k source, you have to train your network on 4k data, and that becomes a ludicrously expensive exercise quite quickly.
