1. Use a stable prompt order

Describe subject and action first, then camera, environment, lighting and sound. A repeatable order makes failed generations easier to diagnose.

CORE FORMULAEffective cost = attempt cost ÷ acceptance rate

2. One motion goal per test

Do not combine several camera moves and complex character actions in the first test. Lock one variable, observe the result and iterate.

3. Write audio as a separate block

Specify dialogue, ambience and sound effects separately. This makes it clear whether a failure came from scene direction or audio direction.

Frequently asked questions

How long should a prompt be?

Long enough to define constraints, but short enough that each instruction can be evaluated.

Should prompts include negative instructions?

Use a short, specific exclusion list only for recurring defects.
