What happens to the rights on a still and a clip if I change supplier?

The pair already delivered, still and clip of that dish, stays on the menu if the use belonged to the venue. Rushes that were never edited do not travel on their own, and the new supplier does not redo the old clip out of habit. Archive the JPG and the edited clip, not only the rushes. In the sierra the hands change and the reel sits on a drive nobody opens. The still and the edited clip are kept, named for the dish.
