How to Repair AI Video Prompts
Diagnose the failure and change one variable at a time
Rewriting the entire prompt changes many variables at once. Classify the failure first, preserve what already works, and edit only the responsible part.
Source review: . Examples are original editorial drafts, not measured generation results.
- 01Classify the failed result
- 02Change one variable per retry
- 03Preserve correct subject and camera details
Classify the failure into five groups
Classification narrows the edit. Keep a correct subject description and a camera move that already works.
- Subject: identity, clothing, product appearance, or count changes.
- Action: sequence, scale, direction, or endpoint fails.
- Interaction: hands, props, contact points, or left-right direction are unclear.
- Camera: shot size and camera movement conflict with subject motion.
- Continuity: background, light, proportions, or space changes abruptly.
Problem one: the action is too broad
“An angry man picks up a cup” leaves the emotional scale, hand, pickup sequence, and endpoint undefined. Rewrite it as an observable sequence.
An angry man picks up the cup on the table with a cinematic camera.
A middle-aged man sits at a table and suppresses his anger as his jaw tightens slightly. He looks down, reaches with his right hand, grips the handle of a white coffee cup, lifts it steadily, and holds it in front of his chest. Locked medium shot, restrained performance. Preserve natural fingers, handle, and cup structure.
Problem two: one shot carries too many goals
Running, looking back, jumping, and waving combined with a fast orbit and a changing environment create several motion paths. Keep the most important action and move the rest to later shots.
Ask whether a viewer can describe the primary action in one sentence.
Problem three: text conflicts with the reference
Adjust the source image or reduce the instruction. More constraint words cannot reliably reconcile contradictory visual conditions.
- The image shows a frontal pose while the prompt asks to preserve a back view.
- The two endpoint frames use incompatible lighting or room geometry.
- The prompt adds a large object with no physical space in the frame.
- The hands are hidden in the image while the prompt demands precise hand work.
Write a retry note before spending again
- Which failure group describes the result?
- What single part changes next?
- Which correct details must remain?
- After two repeated failures, should the reference or shot structure change?
