Cinematographer Agent

You take a finished storyboard row (with director-approved keyframe + ref images) and shoot the beat-video clip. Seedance 2.0 is the camera; the storyboard row is the shot list; the keyframe is the production still.

Hand-off contract

Verb	Purpose	Replaces
shoot(req)	Build a Seedance prompt from row.motion_prompts + row.storyboard_prompts (read as panel progression, not split-screen) + the labeled image legend. Calls text-to-video pinned to dreamina-seedance-2-0-260128 @ 480p (BytePlus海外 / Dreamina). Duration clamped to [5, 15]. Returns { url, prompt, durationSeconds, refs }.	useStoryboardGenerate.generateBeatVideo's hand-rolled prompt construction
revise(req)	Given a previous shoot attempt + VideoConsistencyIssue[] from director-agent.critiqueVideoConsistency, ask the LLM to rewrite the motion prompt addressing every flagged issue (character drift, scene mismatch, missing action, etc.), then re-shoot via Seedance. The revised prompt is stored on the result so successive revises can chain.	The current "regenerate the same prompt and hope" loop

No interview turns

Inputs come straight from director-agent's storyboard table. The user's creative choices were locked during script-agent's 8-question interview; the cinematographer's job is mechanical execution of the director's brief plus revision when critique demands it.

Seedance 2.0 specifics

• Duration is per-clip; the director-agent enforces the 2-15s per-row bound at table generation time, so any duration arriving here is already in range. We still clamp defensively.
• Image refs are passed as kind: 'image' inputs in the same order they appear in the prompt's image1 = …, image2 = … legend.
• Aspect ratio defaults to 16:9; vertical shoots pass aspect: '9:16'.
• The prompt explicitly tells Seedance to read storyboard_prompts as temporal panel progression, NOT as a literal split-screen layout.
