I’m looking at it more and I’m fairly certain this is just interpolated.

Look at this frame:

Seems to me to be pretty normal. No weird hand stuff, fingers look fine.

Now look at the next two frames, particularly the second one:

Totally jank. Fingers are blotchy, there’s a ghost finger, overall looks super fake. But then look at the next two frames:

Second to last has a little bit of weirdness still, but by the last frame it looks totally legit and real. No blotchy fingers, no ghost fingers, overall looks very normal.

That kind of behavior - where some frames look completely fine and in between ones look blotchy and weird - is exactly what you expect from motion interpolation.

Look at the example on a cat video on wikepedia, for instance: en.wikipedia.org/wiki/Motion_interpolation

The framerate is much lower on the original video here, but you can see a lot of the same kinds of artifacts. Blotchy limbs, “ghosts” in movment, things morphing in ways they shouldn’t… its very similar to what’s seen in the trump video. And mind you, to my knowledge this video is done with older interpolation methods that had nothing to do with genAI.
