Quoting IOhannes m zmoelnig zmoelnig@iem.at:
anyhow, [pix_movement] (which is in the stock) should do what you want too.
[pix_movement] compares 2 adjacent frames based on a threshold.
[pix_movement2] compares the current frame against the last 2 ones and a static "background"-image (threshold-based); the threshold adjusts itself automatically; so it is just an improved version of [pix_movement]
You can also use pix_background to remove the 'static' pixels of a video stream. It uses a reference image and threshold to replace pixels within the range with a user specified color. It can be used for keying on non-green screen as well.
