Character Consistency in AI Film: Locked Reference Sheets Beat Prompt Engineering
NecessaryDelay9249 · reddit · 2026-08-21
A workflow for maintaining character consistency across a 30-shot film spanning 60 years and 6 countries. Pure text prompting caused facial drift, so the author front-loaded "locked reference sheets": a four-view turnaround, a six-panel macro sheet (face, hands, fabric, jewelry), and an upper body portrait. These sheets serve as the single source of truth for all prompts, with age and costume changes written as deltas rather than fresh descriptions. Tools used: Nano Banana Pro, GPT Image, Kling 3 Pro, Seedance 2.0, ffmpeg.
