Remove Multiple Duplicate Frames?

[SyntheticEmpathy]

Hi, I have a video from a stream and would like to delete the duplicate frames. So it would go like(a being normal frame, b being duplicate): a a a a a a b b b b a a a b b b b b b a a a.

My question is, is there a script or plugin that detects frames without motion in between frames and then removes them?

I found out that MultiDecimate was the problem, thought it was an entirely different plugin for something else though. Thanks anyways for the link :).
