Video Overviews and Mind Maps
Audio is not the only way NotebookLM turns your sources into something new. Two more Studio outputs help you learn visually: Video Overviews, which are narrated slide-style videos, and Mind Maps, which lay out how the ideas in your sources connect. Some people simply absorb information better through their eyes, and for data-heavy or highly structured material, these formats can beat both reading and audio. This lesson covers both.
What You'll Learn
- What a Video Overview is and when to use it
- How to generate and customize a Video Overview
- What a Mind Map shows and how to explore it
- How to combine visual outputs with the rest of NotebookLM
Video Overviews
A Video Overview is a narrated, slide-style video built from your sources. An AI host talks through the key points while the screen shows visuals: newly created illustrations plus images, diagrams, quotes, and numbers pulled from your documents. It is like a short explainer video made specifically about your material.
Video Overviews shine when your sources are data-heavy or abstract. Seeing a chart, a pulled quote, or a labeled diagram alongside the narration makes complex ideas concrete in a way that pure audio cannot. For a financial report, a scientific concept, or a process with steps, the visual version often lands better.
Generating and customizing a Video Overview
You create Video Overviews from the Studio panel, the same place as Audio Overviews and reports. Before generating, you can steer the output:
- Topic and focus. Tell it what the video should center on.
- Learning goal and audience. "Explain this for a beginner" produces a very different video than "for an expert reviewer."
- Format. Choose an explainer or a briefer version depending on how much depth you want.
Language support has been expanding: Video Overviews began in English and continue to add more languages, so if your preferred language is not available yet, it may be soon. Standard Video Overviews are available across tiers, including the free tier, with daily limits.
Three ways to turn the same sources into something easier to absorb.

| Best for | Learning on the go | Data-heavy or abstract topics | Seeing how ideas connect |

Mind Maps
A Mind Map is a visual diagram that organizes the high-level ideas in your sources into branches and sub-branches. At the center sits the main topic; branches spread out to major themes, and each theme breaks down further. It gives you the shape of your material at a glance, which is hard to get from a wall of text.
Mind Maps are excellent for:
- Seeing structure. Understand how a big topic breaks into parts before you dive in.
- Study and revision. The branching layout mirrors how many people remember information.
- Finding gaps. A thin branch can reveal a topic your sources barely cover.
The best part is that Mind Maps in NotebookLM are interactive. You can expand and collapse branches to control detail, and clicking a node can launch a focused question about that part of your material. So a Mind Map is not just a picture; it is a navigation tool into your sources. You can even explore the map while an Audio Overview plays, learning through two channels at once.
- Your notebook topic
- Theme A
- Sub-point
- Sub-point
- Theme B
- Sub-point
- Theme C
- Sub-point
- Sub-point
- Theme A
The diagram above shows the idea: a central topic branching into themes, each with its own sub-points, exactly the kind of structure a Mind Map reveals from your sources.
Combining the visual outputs
The real power comes from mixing these tools around a single notebook:
- Start with a Mind Map to see the overall structure of a new topic.
- Click into a branch and ask focused questions in chat to go deep.
- Generate a Video Overview on the trickiest, most data-heavy section.
- Finish with an Audio Overview to review everything hands-free later.
Because every output draws from the same grounded sources, they reinforce each other rather than drifting apart. You are looking at one body of material through several lenses.
A few caveats
- Visual outputs, like all AI generation, can simplify or occasionally mislabel. For precise figures, return to the source citations in chat.
- Video generation can take time, especially for large notebooks, so generate it before you need it.
- Availability of specific styles, formats, and languages evolves quickly. If you do not see an option, update your app and check again later.
Key Takeaways
- Video Overviews are narrated, slide-style videos that pull visuals from your sources, ideal for data-heavy or abstract material.
- You can customize a Video Overview's topic, learning goal, audience, and format; language support is expanding from English outward.
- Mind Maps show how the ideas in your sources connect, and they are interactive: expand branches and click nodes to ask focused questions.
- Combine Mind Map, Video, Audio, and chat around one notebook to learn the same grounded material through several lenses.
- For exact figures, always return to the source citations rather than trusting a generated visual.
