The pipeline

17 prompts. 5 stages. One launch-ready script.

1. Competitive Research (prompts 1-2)

Competitive VSL Analysis breaks down what is already winning in your niche. Pattern Library Builder turns it into reusable hooks, structures and proof patterns.

2. Foundational Docs (prompts 3-9)

Sales Page Analysis, Research Methodology Upload and Generate Deep Research Prompt build the research doc. Then the Complete Avatar Sheet, the Complete Offer Brief, the Arguments-First Framework and the Necessary Beliefs Document: the four documents every good script is built on.

3. Script Creation (prompts 10-15)

The Core VSL Script, then five sharpening passes: $100M Hook Machine, Schwartz Awareness Reframe, Bencivenga Belief Audit, Hopkins Specificity Sweep and the Dead Customer Avatar read-through.

4. Production (prompt 16)

B-Roll Scene Extraction turns the script into a scene-by-scene manifest: what to generate, in which order, for every line that needs a visual.

5. Pre-Launch QA (prompt 17)

The 7-Dimension QA Rubric scores the script before you spend a dollar on traffic.

What gets generated

Research, docs, script, manifest, score

Documents (Claude, GPT-4o fallback)

Research prompts run on GPT-4o; the foundational docs and the script run on Claude with GPT-4o as the fallback. Every output is saved to the project so the next prompt can build on it.

Script

Long-form copy in your brand voice, structured the way direct-response VSLs are, with the hook, awareness, belief and specificity passes applied on top of the core draft.

Render it in Video Factory

Take the b-roll manifest into Image Studio and Video Factory. Long Video Chain generates the segments on Kling or Luma, adds one voiceover from Voice Lab (Kling 2.6 and 3.0 keep their native audio), and joins everything into a single video.

Stills on Nano Banana 2 or Nano Banana Pro; motion on Kling 3.0, Luma or Veo 3.1; voices from ElevenLabs or OpenAI.
