The one thing that immediately stood out to me in the ghost example was how the face of the ghost had "wobbly geometry" and didn't appear physically coupled to the sheet. This and the way the fruit in the sloth's drink magically rested on top of the drink without being wedged onto the edge of the glass as that would require were actually some of the more immediate "this isn't real" moments for me.

The ghost is insanely impressive, it's the example that gave me a "wow" effect. The cloth physic looks stunning, I never thought we would reach such a level of temporal coherence so fast.

I think those types of visual glitches can probably be fixed with more or better training, and I have no doubt that future versions of this type of system will produce outputs that are indistinguishable from real videos.

But better training can't fix the more general problem that I'm describing. Perfect-looking videos aren't useful if you can't get it to follow your instructions.
