> You can't get information out of SD video that wasn't there before with upscaling But you can infer visual detail from the information that is already there. Especially because ML uses information from the training set to help make sense of the information that is already there. e.g. if I show you a picture of a key then you can figure out what the lock looks like because the key contains that information, even if it’s not visible.
