AI Walking Effect

Poorly, and it is the single biggest cause of a bad result. If the frame stops at the waist the model has to invent a lower body from nothing, so the legs it builds rarely match the build, the trousers or the shoes you would expect. A full-length shot with some ground under the feet gives it everything it needs.

Because walking is a balance problem rather than a pose problem. The planted foot has to hold still against the ground while the frame moves past it; when the model loses that contact the feet skate and the whole stride reads as a treadmill. Shorter clips and a clearly described camera move both make it much less likely.

Yes, and stylised subjects often hold together better than photoreal humans do, because a viewer forgives an invented gait on a cartoon and forgives nothing on a real person. Character sheets and full-body renders work well as long as the whole figure is in frame.

Pick the length in the generator before you run. Longer is not automatically better here: a short clip that loops cleanly usually beats a long one that drifts halfway through, and since the model is billed by the second, the short version is also the cheap way to find out whether the gait works.

That is what the model on this page is chosen for. Identity across several seconds of motion is where cheaper video tiers give up first, and Seedance 2.0 is here specifically to carry the face, the coat colour and the shoes through the stride.

Only within reason. The location comes from your photo, so you can ask for a different camera move, a different pace or a different direction, but asking the model to relocate someone to a beach while also inventing a walk gives it two jobs and it will do both worse. Change the setting first, then animate the result.

The clip comes back silent by default, which is usually what you want — footsteps generated at the wrong tempo are more distracting than no footsteps at all. Add audio afterwards in whatever you edit in.
