Storytelling & Narrative Structure for Video

Scaling by Duration

Hook Types

The 30-Second Rule

50% of viewer drop-off happens in the first 30 seconds. The hook + tension setup MUST be complete by second 30. Retention curves that survive the 30-second cliff typically retain 40-60% through the full video.

The "But-Therefore" Method

Never connect sections with "and then." Always use "but" or "therefore."

Bad: "Atoms have electrons, AND THEN those electrons have energy levels, AND THEN..."

Good: "Atoms have electrons. BUT those electrons can only exist at specific energy levels. THEREFORE, when they jump between levels, they release light at exact frequencies."

Each "but" creates tension. Each "therefore" resolves it. This is the engine of narrative momentum.

Concept Introduction Pattern

For each new concept in the video:

1. Name it — give the concept a label the viewer can hold onto
2. Show it — visual representation (never just explain with words)
3. Contrast it — "unlike X, this works by..."
4. Apply it — concrete example in the real world
5. Connect it — link to the previous concept with "but" or "therefore"

Pacing by Content Energy

Common Mistakes

• Info dump at the start — frontload curiosity, not information
• No stakes — "here's a cool fact" vs "this changes how you should think about X"
• Too many concepts — one concept per minute is the maximum for retention
• Missing the "aha" — every video needs ONE clear revelation moment
• Symmetric structure — the most important concept should be at 60-70% through the video, not in the middle
• No callback — the close should reference the hook, creating a satisfying loop

Kolbo MCP Integration

Use storytelling structure to guide Kolbo generation workflows:

Scripted Explainer Workflow:

1. Write script using the arc template above
2. generate_speech → narrate each section
3. generate_image or generate_video per scene (with visual direction from script)
4. generate_music → background track matching the energy arc
5. Compose in Remotion or FFmpeg following the timing structure
6. transcribe_audio → generate captions for accessibility

AI-Assisted Scripting: Use chat_send_message with a video-capable model to brainstorm scripts. Feed the arc template as context and ask the AI to fill in each section for your topic.

Creative Director for Visual Storyboarding: generate_creative_director with 4-8 scenes mapped to the arc sections:

• Scene 1: Hook visual
• Scene 2-3: Concept visuals
• Scene 4: Key insight / "aha" visual
• Scene 5-6: Proof / example
• Scene 7-8: Close / callback
