The problem that most of YouTubers have to face in this age is copyright. Since users can somehow download the videos and reup on their own channels, those valued contents may not remain exclusive. Then blockchain appears! And now you bring Video NFT to life. That's awesome!
How exactly this should the problem of reuploading content? I think you can just download the video, edit it a little bit, then upload it again. Whether it's on blockchain or not does not really solve anything. Even if you say the hash is uploaded, by editing the video, it will change, unless there is no download available.
