security search AVI for motion

Got a tricky one that I need help with please.

Is there any software out there that anyone knows that will allow me to go through AVI video and skip to the parts where there is movement?

I have a wireless camera set up to record security footage of my car during work hours.  The camera streams video to a laptop in the boot of the car which runs all day.  So far I have a couple of months of AVI's at 8hrs per day.

The reason I'm asking is that I've just noticed a dent in the car today which I don't remember seeing before and wanted to check the hours of footage to see if I can see anyone causing the damage.

I've tried searching on google and downloaded a couple of freeware bits and pieces, but so far I can't find anything that does what I need.

Any advice please?

Interesting question. There are many security camera recording apps that will start recording only when motion is detected, however in your case you have a continuous recording to scan.

I'm wondering if there's any way of using the AviSynth function MAnalyse (part of the MVTools plugin) for this? I would suggest you try asking in the Doom9 forums.

Many thanks for the advice guys.  I'll have a try with your suggestions over the weekend. :)
