# Multi-source synthesis into a Video Overview — Gemini Notebook prompt

> A three-stage pipeline: synthesise everything in chat, save that answer as a note, then generate the video from the note alone. Generating straight from twenty sources gives you a wandering video; generating from one tight synthesis gives you a focused one, because the model is no longer choosing what matters while it narrates.

## The prompt

```
Produce a structured synthesis of all selected sources that will be used as the single source for a video overview.

Structure it exactly like this:
1. The core claim — one paragraph a newcomer could repeat accurately
2. The three to five points that carry that claim, each with what supports it
3. Where the sources disagree, and what the disagreement turns on
4. What none of the sources establish, stated plainly as open questions
5. One concrete takeaway for someone who has to act on this

Rules:
- Cite as you go; every claim traces to a source
- Prefer specifics — numbers, names, dates — over summary language
- If a point rests on a single source, say so
- No preamble and no closing summary; start at heading 1
```

## How to use it

1. Open your notebook at notebooklm.google.com.
2. Replace the [bracketed] parts with your specifics.
3. Paste the prompt into the chat box and send it.

Square brackets mark the parts you replace with your own topic or question.
