You will never have a better quality than the original, of course.¹ Transcoding with a different codec that makes different compression decisions will not even let you get exactly the quality of the original content, but if you throw enough computing power you can get almost it with a smaller size. What you can get, and where it makes sense to transcode, is a smaller file with lower quality where the lost of quality is much smaller than the gain in size. 1: You might think you can get it with AI, but it only seems better quality. If you do it too much, like if you are trying to catch the face of a replicant reflected on a whisky glass, what you will get is bits of series from Amazon Studios in your videos.
