It doesn't make much sense if you increase video resolution overly. Converting 480p to 4K, for instance. You won't get an actual 4K result, it might only be qualified as one in its size – The pixel points contained within 480p videos per unit area cannot cover the 4k video corresponding part completely and evenly, that will result in blur graphic by sight.
