# 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
