To turn a mind map into a video, first turn it into an ordered outline, because a mind map shows everything at once and a video can only show one thing at a time. Pick a route: the centre becomes your opening question, each main branch becomes a chapter, each leaf becomes one scene with one sentence of narration, and the lines that cross between branches become callbacks. Write a sentence for every leaf (about 150 spoken words a minute), paste the outline into a tool that draws one visual per beat, and check every label. The thinking you do choosing the route is most of the revision value.

The problem: a map has no beginning

A good mind map is radial. The topic sits in the middle, branches spread out in every direction, and your eye can land anywhere. That is exactly why it works on paper: you see the whole subject and how the parts relate.

A video is the opposite. It starts, it goes in one direction, and it ends. Every viewer, including you a week before the exam, sees the parts in the order you chose.

So the real work of turning a mind map into a video is not animation. It is choosing an order. People who skip this step and read the map out branch by branch, clockwise from twelve o'clock, end up with a video that sounds like a list, because the order was set by where there happened to be space on the page.

Choose a route through the map

There are four sensible routes. Pick the one that matches what the subject actually is.

Most science topics are cause to effect. Most biology structures are big to small. Most history is then to now, though often a causal chain is better (see how to make a history explainer video). If you are revising, question to answer is often the best of all, because it practises the shape of the exam answer.

Number your branches on the paper map before you do anything else. That numbering is your chapter order.

Branches become chapters, leaves become scenes

Once the order is set, the conversion is mechanical.

• The centre becomes the opening: a question, not a title. "How does a plant turn light into sugar" rather than "Photosynthesis".
• Each main branch becomes a chapter with a one-line heading.
• Each leaf (the words at the ends of the branches) becomes one scene. Write one or two full sentences of narration for it. A leaf that says "RuBisCO" is a prompt to you; the sentence "An enzyme called RuBisCO fixes carbon dioxide onto a five-carbon sugar" is something a video can say.
• Cross-links, the lines that jump from one branch to another, become callbacks. When you reach the second end of the link, say it out loud: "This is the ATP from the light reactions, arriving here."

Cross-links are the most valuable part of a mind map and the part most often lost in a video. They are the connections an examiner rewards. Do not drop them.

Worked example: photosynthesis

Here is a typical GCSE or high school biology mind map, written as the ordered outline it becomes. Route: cause to effect.

Centre: Photosynthesis. Opening question: how does a plant turn light into sugar?

1. Inputs. Light energy; carbon dioxide from the air, through the stomata; water from the roots.

2. Where it happens. The chloroplast; chlorophyll in the thylakoid membranes absorbs light; the stroma around them.

3. Light-dependent reactions. In the thylakoids; water is split; oxygen is released as a by-product; ATP and NADPH are made.

4. Light-independent reactions (the Calvin cycle). In the stroma; RuBisCO fixes carbon dioxide; ATP and NADPH from stage 3 are used; the product is a three-carbon sugar used to build glucose. Cross-link: back to branch 3.

5. Limiting factors. Light intensity, carbon dioxide concentration, temperature. Cross-link: temperature affects enzymes, back to RuBisCO in branch 4.

Summary equation. Carbon dioxide plus water, with light, gives glucose plus oxygen. 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂.

And here is how branch 3 reads once each leaf becomes a sentence:

The first stage happens in the thylakoid membranes, and it needs light. Chlorophyll absorbs the light energy. That energy is used to split water molecules. Splitting water releases oxygen, which the plant does not need, so it leaves through the stomata. What the plant keeps is energy, stored in two carrier molecules: ATP and NADPH. Hold on to those two names. They are what the second stage runs on.

That last line is the cross-link, said early, so the callback in branch 4 lands. The whole outline comes to about 600 words of narration, a four minute video.

Scene list for branch 3:

1. A chloroplast, drawn, with the thylakoids highlighted.
2. Light arriving at a thylakoid, labelled "chlorophyll absorbs light".
3. A water molecule splitting.
4. Oxygen leaving through a stoma.
5. Two labelled carriers, ATP and NADPH, set aside with an arrow pointing forward to the Calvin cycle.

The simplification here is deliberate and correct for this level: the light reactions involve more steps, but nothing in the outline is false. If your course goes deeper, add the steps to your map first, then to the video.

Make it

1. 1

   Number the branches on your map

   Choose a route: cause to effect, big to small, then to now, or question to answer. Write 1, 2, 3 on the branches in that order. This is the most important step.

2. 2

   Type it as an outline

   Centre as a question, branches as headings, leaves as bullet points underneath. Many mind map apps can export an outline or text directly; if your map is on paper, typing it takes ten minutes.

3. 3

   Turn every leaf into a sentence

   One or two full spoken sentences per leaf, at about 150 words a minute. Mark each cross-link with a line that names where it connects.

4. 4

   Paste it into openCanviz

   Set a target length and choose a style. Doodle on paper suits revision of your own notes; whiteboard suits processes. Use Keep my wording if you want the exact sentences you wrote, which is better for revision.

5. 5

   Check every label against your notes

   Drafted visuals can mislabel a structure or swap two terms. Watch each scene, edit any label that is wrong, and fix any drawing that does not match the sentence.

6. 6

   Test yourself with the map hidden

   Watch one chapter, then redraw that branch of the mind map from memory. Compare. The gaps are what to study next.

What a video adds to a mind map, and what it does not

A mind map is better than a video at showing the whole topic at once. Keep it. Pin it above your desk. The video does three things the map cannot.

It forces full sentences. Single words on a map can hide that you do not actually understand a link. Writing "this is why temperature matters" makes you say why.

It fixes an order you can rehearse. Exam answers are linear. A video practises the linear version.

It is something you can play on a bus. That is useful, but be honest about it: watching is not studying. The revision happens when you close the video and reproduce the map, or answer a question, from memory. How to study from video instead of rereading notes covers how to watch actively.

Common questions

How many branches can one video handle? Five to seven main branches is comfortable for a 4 to 8 minute video. Beyond that, split the map: one video per group of related branches, each with its own opening question.

My mind map is mostly drawings, not words. Does this still work? Yes. Describe each drawing in one sentence in your outline. The video will draw its own visual for the sentence; check it makes the same point your drawing did.

Should the video look like a mind map? Only at the start and the end. Showing the whole map first gives viewers a sense of the territory, and showing it again at the end ties the chapters together. In between, one scene at a time works better than a map that keeps zooming around.

Can I do this for a whole subject? Do it per topic. A whole subject as one video becomes too long to rewatch. Several short videos, each from one map, are easier to revise from. For turning full notes rather than a map into video, see how to turn class notes into a revision video.
