Scenario Seedance Storyboard

Scenario Seedance Storyboard

Overview

Prompted shot by shot, generated movement falls apart: limbs teleport, feet slide, and every cut resets the performance. So storyboard instead of prompting harder. What this delivers is continuous motion through the handoffs, not editorially distinct cuts: for cuts a viewer can feel, cut the delivered clip yourself with scenario-video-editing. Write a timecoded shot script, draw a character sheet and a numbered panel per shot, and hold one rule: every shot ends in the pose the next one starts from. Pinned boundaries leave nothing to reset, so the cuts play as one performance.

Connection and the core loop: the scenario skill; the Seedance parameter contract, conditioning traps, and sound lanes: the scenario-seedance skill; identity across stills and a reusable character sheet: the scenario-consistency and scenario-identity-library skills; a board or comic page that is itself the deliverable: the scenario-storyboards skill; splitting and rejoining shots: the scenario-video-editing and scenario-video-assembly skills. If a sibling skill named here is missing from your available skills, ask the user to install it (npx skills add scenario-labs/skills --skill <name>); unattended, proceed from tool schemas and flag the gap.

Quick reference

Label each panel as a shot list does: number, shot size, angle, lens or camera move, then three action verbs. Arrange them as coverage, not twelve pictures: open on a master that sets the geography, hold one side of the axis so screen direction never flips, climb the size ladder, and punctuate with an insert or a reaction. Adjacent shots share an edge by construction: shot 3's exit is shot 4's entry.

Draw the board light: thin pale line on bare paper, the setting in two or three quick lines, no rendered environment. A board drawn as a competing picture is treated as one, and its markings render into the delivery as objects, which no prompt clause can clean. Drawn light, the same markings transfer nothing, so numbers, captions and arrows can all stay on the board a human reviews. What carries that is prompt wording, not drawing: declare the marks as the director's planning guides rather than prohibiting them, and pass the key frames as concept art so appearance has a photographic source. Both are in video-prompt.md.

Panels are generated one at a time, so one bad panel costs one panel, and gated before any video run on two passes: an AI-quality score for artifacts, and a spot-the-difference against the plate. A board-level verdict is not the bar: panels average defects away.

File as you go: one collection per sequence, created before the first generation, holding plates, panels, repairs, board and video (board-craft).

Stop for approval before the first video run, with the key frames shown alongside the script, plates and board, and invite a reshoot by panel number; unattended, record the assumption and continue.

Two lanes

One scripted run. When the sequence fits one job's duration cap (30 seconds on 2.5 at authoring time), pass the plates, board and key frames as referenceImages and build the prompt to the seven-section shape in video-prompt.md. One generation carries the internal cuts: the plates hold identity, the pose chain holds continuity. Name aspectRatio; it defaults to adaptive here, so a portrait board hands back a portrait video. Reference mode anchors frame one to the base state of the reference world (see scenario-seedance), so a sequence that must open on an exact pose belongs in the chained lane.

Chained per-shot runs. Past the duration cap, when each shot needs its own control, or when the sequence must open on an exact pose: render each boundary pose as a still, then run shot N with image = still N-1 and lastFrameImage = still N, so adjacent shots share a frame both sides agree on. This excludes referenceImages, so the stills are a shot's only identity, and N shots cost N+1 stills and N runs. Each run also has a duration floor (4 whole seconds on 2.5 at authoring time), so N shots cannot total less than N times it, and more cuts than that means fewer shots or more seconds. The disciplines and the repair path are in references/chained-lane.md.
