Use negative instructions to protect the brief—not list every possible flaw
Reliable prompting comes from production decisions that can be checked. Use a small source of truth, describe observable changes, and review the full sequence before rendering.
Define the non-negotiables
Write down the identity, object, location, lighting, or composition details that make the project recognizable. Keep this list short enough to repeat accurately.
Describe one controlled change
For each scene, state what changes during the shot and what remains fixed. Clear cause and effect gives the model less room to invent contradictions.
Review across scenes
Read only the continuity lines, then only the camera lines, then only the timing. This layered review finds conflicts that are easy to miss in one large prompt.
Test with the cheapest scene
Generate a representative short scene first. Improve the source description before repeating a weak pattern across an entire sequence.
Questions about this workflow
Can prompts guarantee consistency?
No. They improve clarity and repeatability, but every result still needs review.
Should I reuse the same master plan?
Yes. Keep one continuity bible and adapt only the scene-specific action.
