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.

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.
