FLUX 3 Video Router

Route a request to the smallest set of specialists that can complete it. When the request already names one narrow job, use that specialist directly.

Default sequence, skipping completed stages:

Prompt Doctor (until READY; owns the shot-structure decision)
  → Cinematic Inserts OR Keyframes & Continuation (one, chosen by whether
    supplied media must constrain the result)
  → Audio & Dialogue (only when sound matters)
  → Generate (only when execution is requested)

Draft before committing anything unproven: a full render takes minutes, and the chosen draft replays at full quality.

A handoff between skills carries: outcome, the route (mode plus its media field: t2v, i2v/keyframes, v2v/start_video, or draft_enhance/draft_cache), the one required action, source roles, invariants, delivery (duration, aspect, resolution, shot structure), camera, audio, text strategy, and risks. It is complete when the receiving skill can act without inventing a consequential choice.

Deterministic requirements (exact typography, frame-accurate sync, final mixing) need an explicit post-production plan, not a generation attempt.
