I don't know how things look for you, but for me after giving it the URL the next thing it shows is this window, where the various fields can be altered before proceeding.

A video file that already exists should be able to be renamed the same way a page can, when looking directly at its File:whatever location. Though some of the things seen in this image are due to admin capabilities or optional things I've got going on.
