I need to be able to control the extraction time interval, the number of extracted frames, moments of extraction, etc.

The effect I have in mind is similar to this:

How should I go about it please?

to do the combination maybe with a jit.op chain……?

good luck!

Even when things are totally dark, camera noise will build up in the feedback chain pretty quickly. Matrixset could be a way to play with it as well

See if my lightpainting patch helps you at all: http://blairneal.com/blog/jitter-example-lightpainting/ …and then come back with something you’ve tried and we can probably help expand it

My example isn’t as clean as some of these other live video lightpainting ones..I’ve always wondered how they get them so clean

jit.wake can be pretty fun too..or jit.slide

That link was a blast from the past. My dad used to fly those funky things. He said the big bananas were the worst, like two choppers tied together with a string.
