Input is a scene idea, image prompt, keyframe or reference video, optionally with aspect ratio, duration, shot count and pacing; unset values default to 16:9, 30 seconds and six shots. The skill locks the parameters, then writes a one-line story spine with an energy curve, a continuity card, a shot table whose durations add up to the total, copy-ready prompts for each shot, global negative constraints and a self-check. It can also recommend camera moves, rewrite or diagnose existing camera direction, and plan first and last frames. The repo declares no license.
