I'm looking to trigger different sound effects stored in a ~buffer. I would like be able to assign sound effects to different pixels area in a video. Imagine rectangles overlaid on a video feed separating areas. When the pixels change in those rectangles (someone moves their hand in front of it) I want the buffers to trigger.

Any ideas/tutorials/3rd party add-ons that I should look at?

an easy way without any actual "tracking" per say would be to get the frame difference (jit.op @op absdiff) then use jit.3m to get the mean. From there it is easy to set a trigger point. You could then divide the screen into smaller segments via jit.submatrix or jit.scissors to several areas...

just one quick, simple possibility.
hope it helps.


Thanks so much, I'll definitely check these out!

I've never really worked in Jitter before, I keep looking through the help files, but it's always nice to have a starting point.
