FanFiltration just posted a link to this in the Off topic Trek thread. It’s a weird hodgepodge of sources. Some cropped, some that looks like it was shot off a screen without a tripod.

One bit I’ve wondered about for years, what episode is the set seen at 11:42 from? I’ve never been able to identify it. Is it even from Trek at all?
I’ve seen just a couple of random bits, but it looks like it’s a merge of the 3 circulating blooper reels, the Billy Blackburn 8mm footage (from the official Blu-rays) and the silent trims, which were previously shared on youtube. So nothing new, but it’s great to see it all together in one video.
