There's tons of UFO videos on YouTube. The problem is that if you exclude the obvious CGI and other hoaxes, that leaves a data set of unidentified objects captured on camera. But that provides little evidence as to what that object might actually be. There are many prosaic explanations: illusions, imaging artifacts, really good hoaxes, top-secret experimental aircraft built by us, ball lightning, etc.
