seedance-2-deep-dive

seedance-2-deep-dive is a skill for Codex from leynos/visual-storytelling-skills. It costs 123 tokens per session (2,647 once invoked), scanned A, original, ISC.

Detailed operating guidance for Seedance 2.0, a video-generation model that can use text plus image, video, and audio references. It focuses on keeping identity, style, motion, rhythm, and continuity consistent.

In plain words
What is it for?
Selecting the model for a shot, preparing multimodal references, writing prompts, choosing duration and output settings, planning batches, troubleshooting artifacts, and checking the live generation schema.
Why use it?
It helps developers plan constrained video jobs and avoid drift or visual errors caused by vague prompts, unsuitable references, or unsupported settings.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

seedance-2-deep-dive scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Seedance 2.0 Deep Dive

Use this skill when shot-specifier routes a shot to seedance_2_0 or when video-generator is about to submit Seedance 2.0 jobs through the Higgsfield Model Context Protocol (MCP).

Seedance 2.0 is best treated as a constraint-driven multimodal video model, not a text-prompt toy. Text describes the new action. Images, video, and audio references carry identity, style, motion, rhythm, and continuity. The practical skill is deciding which constraints matter, passing them explicitly, and keeping each clip short enough that the model does not drift.

Live-Schema Rule

Before any production generation, inspect the live Higgsfield MCP schema through video-generator. Public guidance and creator reports disagree on exact model IDs, quality modes, file limits, duration ranges, and reference roles.

Use the limits below as planning defaults only. If the live MCP schema is narrower, follow the live schema. If the required references cannot be supplied, stop and ask for a production decision.

S01 session 2 observed that the current Higgsfield MCP accepted a Seedance resolution=1080p input while still downloading 1344x768 video, and auto-enabled generated audio without exposing a generate_audio input key. Treat resolution settings as schema-gated quality hints until the downloaded pixels prove otherwise. Treat audio toggles as intent records unless the live schema exposes them.

When Seedance 2.0 Is The Right Route

Prefer Seedance 2.0 when the shot needs:

  • consistent character, costume, product, prop, or recurring visual element identity;
  • multiple image references acting as hard creative constraints;
  • a short but polished action beat, hook, transformation, product move, or b-roll shot;
  • audio-driven pacing from a chosen track, ambience, voice, or sound-effect reference;
  • campaign or sequence coherence across many clips;
  • image-to-video work from carefully designed start and end frames.

Do not default to Seedance 2.0 when the main requirement is maximum native resolution, long single-shot duration, low-setup one-off generation, exact on-screen text, complex hands, or a large multi-character scene with many competing subjects. Consider Kling for camera-motion-heavy exteriors or motion-control work; consider Veo/native-audio routes when generated audio is the asset rather than an input constraint.
