Echo

Good morning.
New to Max/Jitter. Downloaded the demos a couple of days ago, went through the tutorials, looks great.

Now I need a hint to figure out which way to pick to solve my problem.

I have a live video input, I need to store the firts frame, display it. Then I need the second frame to fade on it (using jit.xfade for eg), store the result, and then mix it with the next frame, and so on, in order to obtain some “persistant echo”.

Any clues ?

Thanks
