And I think that's what we are seeing in the video. The eddy current effect isn't permanent like in superconductivity. They have to keep moving the magnet around.

Ah, that's not the video I saw. I was referring to this one : https://sciencecast.org/casts/suc384jly50n
well that one looks great. Maybe in the original video a superconductive effect was there, but not strong enough to frame lock. But you can see it in the newer video.
The new video doesn't show anything convincing either - Pyrolytic graphite behaves the same way at room temps due to strong diamagnetism.
hmmm. This is what you are talking about. https://youtu.be/TlD12QObooc?t=420
