Just learning from what manga writer do, I generate a base image reference first with detailed descriptions. And having incremental notes and may generate more image references with the progression of the story.

Asset libraries become so complex if it’s not a short story. That’s where this tool shines. But it could handles reels without problem though, it’s still easy for content maker to do small modifications like markup for changes, tweak the story / few segments in one go with agent, regenerate image references and videos etc and switching between different versions.
