I agree - probably more than 10 years old - could even be 20 - did you notice the prints were not borderless? I think it's been 20 years since I got back prints with borders.
Some of the photos on the rolls were borderless. White borders are still an option these days (dunno why people like them, though) so it'd make sense to keep them all on one roll if that was one of the magic tickyboxes.
I assume this is something educational made 10 or more years ago before digital took over. It is probably Canadian. Discovery is a cable channel here. I think the image at the very end is Perce Rock, on the Gaspe penninsula (sorry I don't know how to do the appropriate accents on perce and gaspe on my computer). The other side of Canada from here, but one of those iconic images that turns up frequently.
I'll give them to you: Rocher Percé, which is located in the peninsula of Gaspésie, near the city of Percé.
Using film since before it was hip.

My sister in law worked 20 years at a lab like that. It was locally owned, then bought by Konica and then shut down. She gave me cases and cases of outdated color film and plastic frames. I didn't have the heart to tell her I only shoot b&w. I was years giving that cheap film away!
Just think, the video showing the inside of the film processing equipment had to be made with waste film, as it would all be ruined in the lighting required for video or film shooting.
Part of the process of calibrating and maintaining the large Kodachrome machines required the labs to run film leader through the process, until everything was up to spec. Those rolls of leader were very, very long. Although this is clearly C41, they may be using something similar in these machines during that part of the video.
P.S. I frequently order prints with borders at my local Walmart one hour photo. It doesn't seem to create any problem for them.
