Educational explainer video maker for one-prompt lessons

An educational explainer video teaches one concept in about a minute, with a diagram for every step. Describe the idea and who is learning it: Voom writes a script that builds the idea one step at a time, draws each step as it is spoken, and adds a calm voice-over, an original score and captions, in the language your learners speak.

An explainer made from one prompt: how a heat pump works. Made with Voom from this prompt alone, a hypothetical brief with no link.

Prompt Explain how a heat pump keeps a home warm in winter by moving heat instead of making it. Friendly and clear, for homeowners.

How do you make an educational video with Voom?

  1. 01

    Name the concept and the learner

    One idea for one audience: “how a heat pump moves heat, for curious homeowners” or “why the moon has phases, for ten-year-olds”.

  2. 02

    Add the facts that must be right

    Definitions, numbers and the terms your course uses. Voom keeps them exactly as you wrote them.

  3. 03

    Pick the language and length

    Every voice speaks every language Voom offers. 45 to 90 seconds suits one concept; a full walkthrough can run up to 3 minutes.

What happens in the sample film, shot by shot

  1. 0:00

    A question from everyday life

    A girl at a window on a cold night, a heat pump outside, and the question on a notepad: where does the heat come from?

  2. 0:05

    The surprise, said plainly

    The film gives the answer before the detail: it moves heat, it doesn’t make it. Everything after explains that one sentence.

  3. 0:10

    Heat in cold air

    The heat pump stands in the snow while specks of heat drift through the dark, so the least intuitive idea gets its own picture.

  4. 0:13

    Soak, squeeze, warm

    A coil fills with warm colour, a compressor squeezes the line until it glows, and the heat reaches the room. Each step has a short label.

  5. 0:25

    Around again

    The refrigerant cools and the loop is drawn once more, so the viewer sees a cycle rather than a one-off.

  6. 0:30

    The idea in three words

    Back at the window, the girl holds a note that says heat moved, home warm, and the film ends on “moved, not made”.

What makes a short lesson stick

Start with a question the learner already has

“Where does the heat come from on a cold night?” earns attention that a definition does not. A good explainer opens on the puzzle and spends the rest of the film answering it.

One step on screen at a time

Learners follow a process when they see each step arrive as it is spoken and stay until it has been explained. Voom times every picture to its line, so the diagram never runs ahead of the words.

A picture for every abstract word

Refrigerant, voltage, interest: abstract words need a shape. Turning each one into a simple drawn object, used the same way all film, lets learners carry the idea from one shot to the next.

End on the idea in a few words

Close by restating the concept as a short line the learner can remember, such as “moved, not made”. It turns a minute of animation into one sentence they can repeat.

Questions, answered

A short animated film that teaches one concept, such as how a heat pump works or why the moon has phases, with simple diagrams and a voice-over. Teachers use them to open a lesson, course creators to explain a module, and companies to train staff.

Short enough to hold one idea. Most single-concept explainers work at 45 to 90 seconds, and a process with several stages can run two or three minutes. Voom makes films up to 90 seconds on Pro and up to 3 minutes on Business.

Yes. Choose the language of the voice-over, and any of the 20 voices speaks it, with captions in the same language. Voom speaks more than 20 languages, including Hindi, Gujarati, Bengali, Tamil, Spanish and Arabic.

Yes. Voom gives you an MP4 file that you can upload to any course platform, LMS, YouTube channel or slide deck. Videos made on a paid plan carry no watermark.

No. Voom writes it from your prompt and sizes it to the length you choose. Put any terms, definitions or numbers that must appear in the prompt, and the script uses them as written.
