Hi unknowplayer,

I tried to run your code a code a really weird result (I was standing still so no motion at all):

![WeirdResult](https://canada1.discourse-cdn.com/flex036/uploads/processingfoundation1/original/2X/3/3d23aff4802aaf826f3851dc704e466550f477e2.png)

Also I’m not sure to get what you are trying to do but I think it is really close to the effect in this thread: [Framerate in live video delay project : Ed Tannenbaum, Recollections](https://discourse.processing.org/t/framerate-in-live-video-delay-project-ed-tannenbaum-recollections/3129/29)

You might find some interesting informations here.
