I'm new to jitter and getting very confused. There's two things I'm trying to achieve:

* I want to average the luma or brightness of a jit.pwindow across the entire pwindow.

* Then output the level of that luma as a number (I'm guessing it ranges from 0 to 255)

I'm struggling to achieve either of these things.

In the patch there's a pwindow scissored into 9 different smaller pwindows. I'd then like to average each of them individually. There's also a submatrix in there but that was just an experiment.

if you send your normal 4-plane color matrix to a jit.rgb2luma, and then send that to jit.3m, the middle outlet will report average luma as a float.

check out the jit.3m object.

That's exactly what I needed! Thank you so much for the help. Really appreciate it.
