End-to-end video production sequence

Updated May 06, 2026

The sequence diagram below traces the whole video-production chain. The scene-inventory-extractor-v2 skill prepares source analysis, reference images, the prompt keyword library, continuity inventory, recurring visual element references, shot-frame assets, and its Phase 13 handoff. It does not assemble final video prompts or call Higgsfield.

shot-specifier then loads that scene pack, generates storyboard frames through nanobanana, runs and actions storyboard consistency checks, consults the model-specific deep-dive skills during per-shot routing, and writes prompt files plus prompts/manifest.md. video-generator owns the operational run from manifest to local clips: it inspects the Higgsfield Model Context Protocol (MCP) schema, resolves and uploads media, applies model overrides and explicit audio preferences, submits jobs, polls status, downloads clips, updates the generation log, and writes assembly order.

Figure 1 — End-to-end production sequence. The extractor stops after Phase 13 and hands a checked scene pack to shot-specifier. shot-specifier actions consistency findings before it writes prompt files and the manifest. video-generator is the only skill that calls Higgsfield video generation, and it must verify required references, audio preferences, model overrides, and resumable job logging before a shot is considered complete.
