can I save save off to mp4 or other fomarts youtube videos I download with premium?

YouTube Premium allows users to download videos for offline viewing within the YouTube app, but it does not permit saving videos to other formats, such as MP4, or transferring them outside the app. The downloaded videos are encrypted and can only be played within the YouTube app while the subscription is active. If you're looking to save videos in other formats, you'd need to consider other methods, but be mindful of YouTube's terms of service, which generally prohibit downloading content without permission unless explicitly provided by YouTube. Always ensure that you're in compliance with copyright laws and the platform's policies.
