Consistency is the hardest problem in AI film. Models have no memory between generations, so you must supply the memory: reference images, fixed seeds and locked descriptive blocks.
- Character sheet: generate one hero image, then front/side/three-quarter views from it.
- Reference conditioning: feed the hero image into every subsequent generation.
- Locked description: a verbatim 25-word character block reused in every prompt.
- Fixed seed: same seed + same look block = same visual family.
- Wardrobe anchors: one loud, specific item (a red scarf, a cracked visor) reads as identity even when the face drifts.
| Drift symptom | Cause | Fix |
|---|---|---|
| Face changes shot to shot | No reference image | Condition on the character sheet |
| Colour grade jumps | Look block edited | Freeze the look block as a constant |
| Environment mismatch | Rewritten scene text | Reuse an environment block verbatim |
Cut away when drift is unavoidable: an insert shot of hands, an object or the environment hides a character mismatch better than any prompt trick.
