Motion detection software

[nowotny]

Hello

Lets say I have an 8 hour long cctv footage of a room in an avi file... I'm looking for a software that would help me pinpoint the moments where there was some movement/somebody walked in/etc... does anyone knows a program that could do it...?

In case you don't find a motion detection app... Maybe try some bitrate/quantizer analyzer. Sudden movement in a still scenery should result in visible bitrate spikes (as long you don't deal with fixed bitrate video) or a quantizer jump (in case of a fixed bitrate).

I know that AverMedia/AverDiGi surveillance video cards come with software that can scan recorded video for motion in the same way it detects for motion to start recording an event. The hard part seems to be finding a retail or freeware version - Google is only finding software for recording.
