Hello friends. I don't have much experience with youtube so I was hoping someone might help me out with advice. I want to download the video from youtube and re-upload it back with my watermark. I tried it with youtube downloader, downloaded the video, added a watermark but when I trried to upload it it got refused by a server for copyrighted content. Is it audio that gives it away or is there some other parameters they looking at? What can I do to change the video enough to upload it ? Please help.
