Music video with Guaardvark

Read setup first. Needs the comfyui plugin and an installed i2v model (wan22-5b by default; minimax-h3-int8 for frame-matched continuity).

Start: MCP generate_music_video

• song: document id or a filesystem path to mp3/wav/flac/ogg. A path is uploaded for the user.
• style_prompt: mood, palette, movement, era ("grainy 16 mm, neon rain, slow dolly, 1984").
• name (defaults to the song file name), i2v_model (defaults to the active i2v model).
• The tool analyses the song (tempo, beats, sections), writes one unique prompt per cut and stops at the approval gate. It does not spend GPU rendering clips. Tell the user that.

The gate and the rest of the pipeline (REST)

B=${GUAARDVARK_URL:-http://localhost:5000}, ID = the project id the tool returned.

Creating a project without the MCP tool: POST $B/api/music-video with {"name", "song_document_id", "style_prompt", "settings": {"i2v_model": "..."}, "user_treatment": "optional short story"}. user_treatment becomes the creative source the Director writes cuts from.

How to run it well

1. Start the project, show the cut list and the beat count.
2. Offer storyboards before approval: they are cheap and catch a wrong style early.
3. Ask for approval in plain words with the cost: number of cuts times the clip time for the chosen model. Approve only after a clear yes.
4. Character in the video: create a Cast subject and train a LoRA first (the cast skill) so the Director can lock identity across cuts.
5. The finished cut is assembled to the detected beat grid. The Video Editor page can trim or overlay text afterwards.
