AI video prompt repair
Negative prompts should name visible failures.
“No artifacts” is too vague. Build negative direction from the actual risks in the shot, then keep it compatible with the positive direction.
Identity
No face morphing, age drift, hairstyle changes or inconsistent skin details.
Hands and body
No extra fingers, fused hands, limb duplication, sudden pose jumps or body warping.
Products and text
No logo rotation, label drift, geometry changes, duplicated objects or unreadable text.
Camera
No unintended zoom, orbit, pan, shake, focus breathing or framing drift.
Background
No wall deformation, moving furniture, lighting flicker, texture boiling or new objects.
Timing
No abrupt acceleration, action repetition, frozen motion or movement outside the stated interval.
Copy-ready pattern
Preserve: exact face identity, finger count, clothing, product geometry, label and background layout. Avoid: camera movement, facial morphing, extra fingers, text drift, object duplication, focus breathing and background warping.
Only include failures relevant to the scene. A long generic blacklist can conflict with the shot you are trying to create.
