Surprisingly, it looks like Wan 2.2 can do a fairly decent realistic heart in gens if you use the heart \(organ\) tag in your prompt; I suspect it has some live surgical footage in its training data.

Apologies for the furry, but I was doing some testing...the downside of Wan 2.2 is that the heart never seems to *beat* no matter *what* kind of prompt I put in.

Not sure how feasible it'd be to make a LoRA to get a heart motion at all either...hmmm. Any advice? I don't think my local desktop could handle doing LTX-2, not enough RAM (NVidia 4070 Ti Super with 16 GB VRAM, and I *think* 32 to 48 GB of DDR5 RAM)...
