Rename (movie) files by size/timestamp ?

I would appreciate a feature to create names of my video files based on file size and preferably also on how long the file clip is (min.sec)
Since I have a lot of files that have very similar names (mov001..mov002 .. end so on :-()
I would be very happy if it were possible to add to each file the previously mentioned information automatically .
Is this someone who would be able to become possible?
Adding only creative dates is not enough for my needs.
