Does anyone actually have a source that shows YouTube has actually implemented technology that is doing this? Contrary to popular belief music videos are still encoded and mastered for delivery to VEVO by a few companies. Universal Music also has one of the largest catalog of popular artists. VEVO transcodes them and publishes to their platform. If they let Google transcode them or not I do not know. Depends on the partnership. https://support.google.com/youtube/answer/3079146?hl=en https://support.google.com/youtube/answer/3079146?hl=en
