Video of Darkroom Processes

I'm creating a power point for school on careers in photography and I'd
really like to have video clips of a picture being placed in the
developer, someone using a larger, using a black bag, even the dark
room doors opening or closing. I don't have access to a dark room now
(or a video camera for that matter) if anyone knows of any footage, I'd
greatly appreciate you sending it my way.

Thanks,

Jeff
