Im trying to mix a still greyscale image from [jit.qt.movie] with a greyscale [jit.noise], but i want to be able to split the [jit.qt.movie] into two types of values. So if a single pixel value in the [jit.noise] goes above an (input variable) value. the related pixel in the [jit.qt.movie] is blacked out.

Ive tried loads of ways of doing this with different max maths solutions but the patches get far to heavy. I've even tried building a 64 by 64 ubutton solution with an fpic and that took ages just to watch it work in super slow motion :/,

Im an extreme novice with jitter but I'm confident there will be a much more simplistic approach to this in jitter than the methods I am using at present.

Please could someone save me from the madness that will when its complete look like quite a boring patch, ha ha

Think you need to use jit.op @op @> 125(change this value as you see fit assuming its a char matrix)

You can also use the jit.op objects to compare multiple matrixes.

The jit.expr object is very useful as well.

check the jit.op objects

the iit.op was perfect, I used it with it.alphablend and got the exact result i was looking for.

thankyou

For much faster results you can build any op objects in jit.gl.pix. Its gpu based and far simpler than it seems. Check the jit.gl.pix alphablend example.
