I just can't believe the crap you are writing here. Yes, exactly Google is the friend, but there are a lot of hidden things on Google besides commercial things, Because of that, we are all here on the forum. If you don't know how to help someone, don't write anything, and btw, there is no one free tool that removes watermarks that will do the correct job; at least I don't know any. If you have, for example, something with a high contrast behind a watermark, it will be so obvious, and I guess everyone needs a high-quality video.
