How to verify the authorship of the video?

Question

Video

Good afternoon, there was a situation, the video I shot was posted on facebook, but I don’t want them to post it, how can I confirm the authorship of this video so that it can be deleted? Whoever posted is asking for proof that the video is mine..

Answer 1

My reflection. Write that because they published without your consent, then you contact the site closing service (I forgot what it is called). You give them a chance: let them send you the name of the author, and in return you can send a scan of a page of a passport or other document.
And for the future: put a digital mask.

Answer 2

How did the video end up with third parties? Did you post it publicly? If so, then it is possible with loss of quality, or you have a longer video (sources in general).
You can try to write a complaint to facebook, attaching something from the above, but I don't know how it works. You can go to court, but you have to be prepared for difficulties.
Don't give up - thieves need to be punished.
UPD: Of course, if we are talking about the fact that the video was downloaded from somewhere and uploaded somewhere. If, for example, you posted a YouTube entry using standard means, then this is normal, you yourself agreed to this when you posted and allowed it to be shown on other sites.
