is it possible to process video in float?
since movie files are never float, how can i convert a char matrix into a float one? and will i have to convert the result back into char in order to view in a window?

Just make a jit.matrix that is of type float32. Connect that matrix to a jit.pwindow or jitwindow. easy as that. of course all values will be from 0 to 1 instead of 0 to 255.
why do you want float values?
Here is a quick example…cellblock is being used to display the values of each cell for each plane.

thanks thats perfect
so the pwindow / window automatically interprets 1 as white instead of 255, thats useful.
i want float because it makes the maths easier when using simple + and * operators to mix images together. also, i want to be able to use negative values in the matrices.
im a compositor by day and float makes more sense to me…

when doing operations…jit.op makes life much better and is less processor intense as the normal max operations. You can also use jit.expr instead of stringing a bunch of jit.op together. There is a good tutorial on jit.expr by andrew benson on the cycling website.
