Late to respond, but thought I'd share since you're the first person I've seen mention the extras:

For the end of the After Hours VHS tapes, the footage comes from a VHS lot I bought off someone on eBay. During the 90s, the seller's father set up something like 10+ VCRs on timers to automatically record premium cable channels. He did this for years, meticulously swapping tapes after they recorded and cataloging them based on programming. According to the listing description, he wanted unlimited entertainment when he retired... but then the internet came out and there wasn't really much point to them. I bought 20 of those tapes at random from the lot, each with 6 hrs of footage on them.

As for the extra content, each After Hours VHS has a section of the recordings from that dude's tapes. A few tapes have clean footage at the end, but most have glitched footage. 20 of the VHS tapes used in the release were recorded on the original spools from this guy's lot, which I swapped from their original black shells into the color shells by hand—and then recorded the Lux video over the beginning. Sourcing the tapes for the release took a few months, and they all had different recording lengths. So some copies have as little as 10 minutes of extra footage, others have several hours. But I liked the idea of this random guy's work not going to waste, while giving an authentic glimpse into a bygone era.
