Prompt only what the image cannot show. A still image already contains subject identity, product form, wardrobe, palette, composition, and background. Re-describing those static details often causes drift. Add motion, camera, timing, transformation, lighting change, audio, and preservation constraints.
@Image1 is the reference; preserve [identity/product/scene] exactly. Only [motion] changes. Camera: [one move]. Lighting: [source or transition]. Sound: [cue]. Constraint: [what must not change].
Field-observed from Chinese practice; decide the mode before writing.
- Hold mode (the image is the moment): distribute three or four natural micro-actions across the clip - a blink, a breath, hair drift, a slow gaze shift - and lock everything else with a double statement, positive plus negative:
she stays seated by the window; she does not stand, turn, or leave frame. No camera move, or one slow push-in at most. - React mode (something happens to the subject): expand one emotion into sub-beats with real time to land -
she registers the sound, her eyes widen, color rises in her face over two to three seconds. Rushed emotions read as glitches; give the key beat at least two seconds. If the image is clearly mid-scene rather than a natural opening frame, anchor the start explicitly:the clip begins exactly at this moment.
Use precise locks for fragile anchors: preserve face identity, preserve logo and label, preserve bottle shape and cap geometry, preserve outfit and hairstyle, preserve room layout. Do not lock everything if the scene needs natural motion; lock only what must remain stable.
| Add | Example |
|---|---|
| Micro-expression | subject blinks once and lowers their eyes |
| Product light | thin highlight travels across the label |
| Weather | rain streaks behind the subject; droplets bead on the surface |
| Camera | slow dolly-in from current composition to tighter detail |
| Atmosphere | dust catches the doorway beam and settles |
| Audio | soft room tone, one key click at the endpoint |
- If identity drifts: reduce new visual description and strengthen preservation constraints.
- If camera jumps: use one camera move with start and endpoint.
- If product warps: say preserved, static identity, no shape change, no transformation of the product.
- If output is still: add one physical action and one time cue.
- If background changes: preserve environment layout and animate only light, weather, or atmosphere.
- If hands deform: simplify hand motion or keep hands outside the main action.
