Motion Physics Director
Action prompts for Kling that describe weight, contact and material behaviour, with a checklist and a fix for each way the motion usually fails.
When to use
- A shot has visible physical action: running, lifting, throwing, pouring, dancing, falling fabric.
- Earlier clips had floating limbs, sliding feet, rubbery objects or odd speed changes.
- You want a repeatable way to write action prompts.
When not to use
- Mostly static shots (portraits, landscapes): physics wording adds little.
- Fights or multi-person choreography in one clip: split it into single actions first, one clip each.
- The motion is a camera move rather than subject motion: use Camera-Move Storyteller or the Camera-Motion Dictionary.
Example
User: A woman lifts a heavy wooden crate of apples onto a truck bed at a farm. Real time, medium shot, 8 s.
Result (abbreviated): CLIP PLAN: the lift and set-down only; walking to the truck becomes a separate clip. KLING PROMPT: An orchard in afternoon sun beside an old pickup. A woman in a denim work shirt bends her knees and grips both rope handles of a heavy wooden crate full of red apples, knuckles tightening. At the 2nd second she lifts with visible strain, leaning back to balance the weight. At the 5th second she swings it onto the truck bed; it lands with a solid thud and the apples jolt. Medium shot, static camera. Creaking rope, the thud of wood on metal. Her boots stay planted; the crate stays rigid. CHECKLIST: [ ] the crate does not move before her grip -> if it fails: start the prompt with the grip, not the lift.
Illustrative example; actual output will differ.
