Design the source for motion
Use a rights-cleared frame with stable identity, clear depth layers, intentional lighting, and enough negative space for the planned movement. Repair anatomy, product geometry, and text before animation.
Separate camera and subject direction
Write subject action, camera path, speed, environmental response, and end state as distinct instructions. Choose one primary camera behavior instead of stacking unrelated moves.
Route to the right model
Compare models using the same image and motion brief. Score identity, object permanence, physics, lens behavior, flicker, first and last frames, usable seconds, and retry cost.
Finish with human review
Approve motion before sound, extension, enhancement, or lip sync. Preserve the source, prompt, model, settings, and rights record; compare Higgsfield with Polox AI or Kling using the same rubric.
