GSVideo pixel extrusion

Contributed Library Questions

I've been working on a script that takes video and extrudes each pixel based on brightness or color values. I've gotten it to work using GSCapture and my webcam but I cant get it to work on a quicktime movie. i've incorporated the PeasyCam library to be able to orbit around and zoom into the pixel cloud. So, i'm not sure where to insert the mov.read() and loadPixels() commands --- in draw or movieEvent? will that matter? For GSCapture, it works in draw. running windows on macbook.
Does anyone see what im doing wrong here? i'd really like to get it going using a .mov file (GSVideo) rather than the webcam (GSCapture). Thanks!!
