How do you keep hands and faces from distorting in AI video?

On Higgsfield: Against broken hands and faces Higgsfield's blog advises structural fixes: a Soul ID trained on a real identity so the face is not reinvented, Cinema Studio camera parameters, and a reference image of the gesture.

Without Higgsfield: Write the action one beat at a time as a start and end position, and name every point of contact, since unnamed contact is where extra fingers and fused hands come from.

Axis: structural fixes (trained identity, controlled camera, references) … prompt wording and regenerating
