Hand Integrity Lock
Hand Integrity Lock is a rescue prompt for creator and product videos where hands are unavoidable. It is especially useful when the hero shot involves holding, rotating, or presenting a product close to camera.
- Best generation mode
- Reference to Video
- Recommended duration
- 4 to 6 seconds to protect continuity before extending or iterating.
- Recommended aspect ratio
- Match the output ratio to the final destination, but avoid reframing mid-shot if geometry fidelity matters.
Fix one of the most common Seedance 2.0 failures with this hand-integrity prompt. Ideal for UGC product holds, demos, and creator videos that need cleaner hand anatomy.

Prompt
Use this as your base prompt, then adapt the subject or style to your own asset.
When hands hold @Image1 product, keep five-finger anatomy stable
Negative Prompt
Keep the constraints tight if product fidelity, anatomy, or readability matter.
extra fingers, fused fingers, hand blur
Why this prompt works
- These prompts tell the model what must remain stable before they ask for motion or atmosphere.
- The constraints are specific enough to reduce common failures like drift, warping, and anatomy errors.
- It names the exact anatomy failure the model should avoid instead of only saying make it realistic.
Recommended setup
Input guidance
Use a clean reference image for the hero object, face, or hand pose. These prompts perform best when the model has a strong visual anchor.
Camera notes
- • Continuity prompts are strongest when the camera move is deliberate and limited.
- • Keep the product-holding action simple and centered. Complex hand choreography will still break anatomy.
- • Use a tighter shot only if the hand pose is well anchored in the source reference.
Style notes
- • Consistency improves when the prompt limits variation instead of inviting stylistic drift.
- • This prompt is anatomy-first. Style should support the hand-and-product read, not compete with it.
- • Clear lighting on fingers and knuckles helps the model understand separation between digits.
Prompt variants
Use these when you want the same idea with a different shot feel, pacing, or presentation style.
Variant 1
@Image1 product held in one stable hand, five-finger anatomy preserved, subtle presentation movement, no fused fingers no extra fingers no hand blur
Variant 2
@Image1 creator hand holding hero product toward camera, clean anatomy lock, realistic skin detail, no clipped fingers no product slip
Variant 3
@Image1 close product hold shot, hand integrity prioritized over flashy movement, no finger duplication no warped grip
Common failure modes and fixes
Identity or product geometry changes across frames
Shorten the shot, lower motion complexity, and put the stability rule earlier in the prompt.
Continuity improves but the video feels static
Keep the lock instructions, then add one subtle motion layer such as a slow push-in, hand adjustment, or lighting shift.
Hands improve, but the product starts drifting instead
Reinforce both anatomy and product geometry together, and keep the hold pose more static.
