This is a really good capture from Gębice, Poland and released by Grupa obserwacyjna. This is very clear footage of a sphere hovering before it just disappears inside of a thunder storm.
It would be nice if we knew the name of the person who recorded this or better yet, and interview him/her on camera. Otherwise it's suspect as a possible CGI job. I look at footage like this and think why would you not want to take credit for that video?
