CORE FORMULAEffective cost = attempt cost ÷ acceptance rate
2. Increase difficulty gradually
Test a static close-up, simple turn, full-body motion and multi-shot sequence in order. This reveals the failure threshold.
3. Budget per approved sequence
One good clip does not prove continuity. Calculate cost for the complete approved sequence, including replacement shots.

Frequently asked questions
Can prompting alone guarantee consistency?
