Looks pretty sluggish at 5:00, not that I'd even expect this class of system to handle that kind of video project all that well regardless of RAM pressure.
6:49 to 7:00 is how long Photoshop takes to go from the preview to the viewing the original resolution image zoomed in. Quite sluggish.
Dumping a bunch of out-of-focus idle apps into swap not only isn't the best test, but also isn't a magical solution that has no downsides even if it stays responsive a lot of the time.
There are all kinds of ways relying on swap can quickly turn your system into having a storage/memory bottleneck rather than a CPU bottleneck and they have very little to do with having a ton of backgrounded idle apps open.
He even mentioned one of them, which was screen recording, since that's adding write cycles to the disk while your system is also competing for disk writes for swap memory.
For example, let's say I'm downloading/extracting a large file (e.g., a game on Steam) while I have a lot of Chrome tabs and programs open with a good amount of RAM pressure. Now I might see more sluggishness than if I had a larger amount of RAM and the exact same system specs since my swap is competing with file write activity.
This isn't some kind of exotic uncommon activity.
A YouTuber doing a quick "open a bunch of apps and play around with them" doesn't necessarily test the kind of specific actions that would deal the most damage to a RAM-starved system.
