One example: I have a bunch of segments to slate, I'd like to create a macro that goes 20 seconds back from the beginning of a segment, mark in, go +9:29, mark out, record, go forward to next edit. Repeat ad nauseum.
I know there are unsupported 3rd party solutions that may or may not work, but we can only use programs that our engineering department determines are necessary and that they install on the computer. So I'm counting on Avid here.
