You could downrez the images and bring the pixels into CHOPS with an
image CHOP over the specified time span. You can get min/max in two

- It's easy enough to do a min/max with an Envelope CHOP and a huge
window value.
- Alternately you can shuffle CHOP swap channels and samples and then
look up the min and max chan values with a chop expression.

I have a couple hundred frames and want to intelligently do operations across the entire sequence like min/max/average/etc.  There isn't a loop operator in COPs so is there any easy way to do something like this?
