ELI5: How do Youtube channels “remaster” their old videos without reuploading?

r/

I see this more often in music artist channels. How do they upload a high-quality version of their old music videos without necessarily reuploading the said video (deleting and uploading it again)?

    A Youtuber I follow once explained in a podcast that once you are big enough, you have direct contacts at YT you can talk to about these things.

    My information may be outdated but I believe it’s almost always that they have a contact at YouTube that (all large channels do) that is able to replace the actual video content of a YouTube video

    That’s something Youtube allows music labels to do. They don’t let regular people do this, because it would definitely be abused to the max (gather upvotes and positive comments and then replace the content with something horrible).
