Agent/AI product promotional video creative director layer: first lock in the product protagonist, audience belief change, and video format, then translate invisible Agent collaboration into a shootable story with shots, motion, sound, and provenance contract. Use when: user asks about directing/editing/narrating/sound design for Agent product promos, wants to break down a reference video, write a creative brief/beat sheet, or video-forge pre-production hasn't locked the subject and camera grammar. Not for: post-brief recording/TTS/alignment/rendering (use video-forge), tutorials/feature walkthroughs, pure animation production (use anime-forge), or just finding time-sensitive competitors (use deep-research first).
