What is a myth busting video?
It is a short video of an expert talking to the camera. They say one widely held belief in their field out loud, then show why it is wrong.
- It has five parts: the myth, why people believe it, the truth, one proof and what to do instead.
- The speaker is someone with first-hand experience, like a heating engineer, a dietitian or a tax adviser.
- The myth appears as text in the first second, so viewers with the sound off know what is being challenged.
- It runs 35 to 45 seconds in a vertical 9:16 frame.
- Correcting a common belief shows you know the subject better than the usual advice does.
- Each video covers one myth. A list of five myths is a different format with a faster pace.
How to structure a myth busting video
Give about 9 seconds to why people believe the myth. Many creators skip that part, and it keeps the viewer on your side.
- The hook gets 4 seconds. Say the myth and mark it false in the same sentence.
- The truth gets about 11 seconds.
- The proof gets about 10 seconds: a number, a test you ran or what happens to your customers, not someone else's opinion.
- The last 8 seconds are what to do instead, said in one sentence.

Example script: a 42-second myth busting video
This made-up example is a heating engineer. Each row is one part of the structure above.
Myth busting example script for a heating engineer
103 words. Read at a brisk, natural pace, it runs about 42 seconds.
| Part | Time | What you say |
|---|---|---|
| Hook | 0-4 s | Leaving your heating on low all day does not save you money. |
| Why it sticks | 4-13 s | I hear it every week. The idea is that the boiler works harder to warm a cold house, so keeping it warm must be cheaper. |
| Truth | 13-24 s | It is not. A warm house leaks heat all day, and the boiler keeps replacing it. You pay for every hour of that loss. |
| Proof | 24-34 s | I ran both on a meter in the same house, two weeks each way. On low all day cost about a fifth more than two short bursts. |
| Do this | 34-42 s | Set the timer for thirty minutes before you wake up and before you get home. |

Hook lines for a myth busting video
State the myth and mark it false in the same sentence. Fill in the brackets with your own details.
- [Common advice] does not [promised result].
- Stop [habit]. It is costing you [specific cost].
- Everyone says [belief]. I have [credential], and it is wrong.
- Example: Leaving your heating on low all day does not save you money.
Where to put the headline, b-roll and captions
Put the myth on screen as a headline from the first frame. A viewer with the sound off reads it, recognises their own belief and stops.
- Keep your face on screen, under the headline, while you state the myth and give the truth.
- Use b-roll while you explain why the myth sticks, and again for the proof.
- A warning-style or stamp-style headline signals a correction before you say a word.
- Burn the captions into the video, so the correction reads with the sound off.
Common myth busting mistakes
A myth busting video fails when the viewer feels mocked, or when nobody believes the myth. Pick myths from your own inbox, not for shock value.
- A myth nobody holds is not worth a video. If no customer said it to you this month, pick another one.
- Skipping why the myth sounds right makes the viewer feel stupid, and they stop listening.
- Your job title alone is weak proof. Give a number or a result first, then your credentials.
- Leaving out what to do instead leaves the viewer stuck. Tell them in one sentence.
When to use a myth busting video
It works when buyers act on a belief that costs them money, time or results, and you can show the cost.
- It suits a new type of product, because you can correct what people already assume before you explain what yours does.
- Tradespeople and clinicians use it to answer the belief they hear every week.
- Online shops use it when their product goes against common advice.
- It needs a real expert. Say in one sentence why you know, like how many boilers you service a year.
- It works well as an unpaid post on Reels, TikTok and Shorts, because people share a correction with a friend who believes the myth.
- As a paid ad, it ends on a product that makes the new habit easy, like a heating timer.

Questions people ask
- How long should a myth busting video be?
- 35 to 45 seconds. The example script here runs 42 seconds and 103 words. That leaves room for the part most people leave out: why the myth sounds right. Without it, the video is shorter but less convincing.
- How do I find myths worth busting?
- Start with your own inbox and comments. A myth worth a video is one a customer said to you in the last month. Sales calls, support tickets and the questions under competitors' videos are good sources too.
- Should I name who spread the myth?
- No. Correct the belief, not a person or a competitor. If a rival's advertising started the myth, say it in the words a customer uses, such as "you need a separate product for that", and correct that sentence. Naming a source turns the video into a dispute.
- Is a myth busting video the same as an unpopular opinion video?
- No. A myth busting video corrects a factual belief with proof. An unpopular opinion states a judgement others in your field disagree with. If you can prove it with a number, it is a myth. If you can only argue it, it is an opinion.
- Is there a tool that edits myth busting videos for you?
- Yes. Cutroom turns one video of you talking, up to 3 minutes long, into a 9:16 video with the myth as a headline, captions and b-roll. A 30-second video costs 110 credits, and your first video is free.
- What if I have no numbers of my own to prove it?
- Use what you have seen. A test you ran once, the before and after from one job, or the same result across your last ten customers all count as proof. A manufacturer's spec sheet or a published guideline works too. Your job title on its own does not.
- When is a myth busting video the wrong format?
- When you cannot prove the correction, or when the claim touches health and you are not qualified to make it. Share your experience as a founder story or a day in the life video instead.
Say the myth, film the five parts in one go, and let Cutroom put the headline on screen. Your first video is free.
