I am experimenting with slit scan techniques found in the forum and from other examples. i wanna achieve something similar to this:

How can you write two different things in one jitter matrix? Like a live view and the slit scan image? when you use jit.scissors and glue pairs it is kind of a workaround but as in this video i want to use a flexible scanline...

what about the framerate when it comes to higher reslutions?

this iphoneapp seems to handle a max resoltion of 2048×640 which leads my patch to a framerate to around ten.

cam input - jit.matrixset - jit.submatrix - jit.matrix. i actually dont get why leaving the jit.matrixset out leads to a slower framerate.

any help and ideas appreciated!

You could send your effect-image send to one jit.gl.videoplane and the live view to another jit.gl.videoplane that share one common render-context, so that the 2 planes are just arranged next each other (and you can dynamically resize the 2 videoplanes then.

Regarding speed: Did you try to make the scanline > 1? Maybe you can try to scan f.e. 5 or 10? then you don't have to count so many steps and I think image should still look smooth...
