Use an image-to-video workflow (Seedream still → Seedance animation) instead of text-to-video so Seedance can match a reference image and keep the character consistent across shots.
Only send “clean”/approved frames to Seedance for animation (filter out wrong faces/characters first) to avoid paying to animate bad renders and cut your Seedance render cost.
Have your LLM generate per-shot prompts and explicitly mark which frames are clean/keepers; animate only those marked frames in Seedance.
Design characters with countable, checkable features (e.g., “3 eyes in a row”) so you can reliably verify frames before animating them in Seedance.
