I intend to make a program that analyze video and convert it to sound. I read some tutorials, checked some jitter objects, and got to these conclusions:

1 - I need to be able to get the animation appearing in jit.scope.maxhelp, and grab that information somehow.

2 - I need to be able to convert the output matrix of those 3 RGB jit.pwindow in jit.histogram.maxhelp to 0-127 MIDI values, or any other scaled range

...the problem is that I have no idea how to convert jitter matrixes to a scale (I think I need to be able to grab just the x vector of the x,y matrix).

Any help would be truly appreciated...
Happy Holidays!

jit.op will help you scale the values (* and + for a simple linear scaling)

To get the values from 1 plane, use jit.unpack

jit.unspill will give you a list

Hope you don't have a tight deadline.
Happy holidays,

Sorry, but I didn't find [jit.unspill], did you spell it right?

And how do I scale values of a single plane with [jit.op]?

Please redirect me to maxhelp patches, tutorials, or a homemade patch. Thank you for all the help.

any other suggestions are truly welcome! :)

i think you meant [jit.spill], right?
I found a Tutorial that may be useful
Tutorial 11: Lists and Matrices

any other suggestions are truly welcome! :)


I know this was written a long time ago, but is there anything you can recommend for a logarithmic scaling of a matrix? I'm having real trouble trying to find something.
