Is not exxactly as you said.....except if thye copyright holder will not give to the buyer the authorization to resell or give away 🙂
I'm not talking only to talk, i'm a lawyer and those cases are very common in my office, even if in the end the copyright holder receive only the price that the seller acquired when it sells material that is not produced and copyrighted by him (ad imagine that the legal and rocessual expenses are not so cheap...except if you don't want to go on a tv show like people's court or similar ^_^ but i doubt that anyone wil go on tv to talk about tickling videos or clips lol)
Of course not all the companies give to you so many restrictions, you should ask to the company that produced the video(s) if is possible to resell or give away for free them before selling.

Anyway good for you that you bought those videos 🙂
