The first tool I tried, HitPaw, was absolutely awful.

The second tool I tried, Klingai, allowed me to give an animation prompt. I gave it "A young woman smiles and waves at the camera", using a different base image.

The face is excellent, but the finger look as if they're made out of jelly.
Klingai had a wait time for free renders of "3+ hours", so I didn't get the result until this morning. The third tool I tried, DeeVid, produced its result within minutes (using the same prompt).

That's frighteningly good, or, as my wife more succinctly put it, frightening. There's still a little jelliness about the fingers, but it's nevertheless very impressive.
It was so impressive that I used my second free go on another image, this time a full-length one. My prompt here was "A young woman looks at her shoes then laughs at the camera".

I particularly like the movement of the skirt out of the way.
There are plenty more such tools out there.
Sadly, I don't have any actual use for any of them.
