| If the result… | Why | Fix |
|---|---|---|
| The result drifts from the preview | Too many fields changed at once. | Reuse Camera Focal Length Test as-is first, then change one group — subject, light, or setting. |
| The model over-stylizes the scene | The prose prompt leaves finish and camera underspecified. | Add one camera or lighting sentence and stay on Seedance 2.0. |
