Is there a way to fast-forward previously digitally-recorded video based on motion-activation?

That is, the video was recorded in a continuous 30 day loop 24/7.  I'm looking for a way (after-the-fact) to review that recording so that I am only seeing video that has motion recorded.  I know there are cameras that record this way but I am looking for a way to review video that wasn't recorded with motion-activated technology.

Yes, it does have a time stamp (darn it).  I would have thought that there would be enough demand for something like this that someone would already have a solution for this.  Thanks, MASQ - I'll check out the player speed options.

One of the ways video compression works is to analyze successive frames and just save the differences.

With a program like Matlab, it would be simple to calculate a difference threshold, and only show frames where something is changing.  It would also be very easy to mask the section of the frame with the time stamp.

Thanks, d-glitch. Matlab sounds a little too technical for me.  I was hoping for an off-the-shelf solution.
