You can use ttdownloader.net it's working fast and there are no ads!

thanks for the link! but I don`t think it is a ptoblem if watermark is on the video

Yep. But good services that completely remove watermarks are quite rare. Maybe not, but people use the services that just blur the watermarks because of how accessible these are. I can share a good link for you here https://qload.info . That's the good the best one I saw. It is fast and it removes everything.

How do people remove watermarks? I know for a fact that it is possible as I saw reuploads without watermarks. The question is where can I get tools for it?
