Explaining a technical product on film

Technical businesses tend to produce one of two films. Either a corporate piece full of sweeping shots and adjectives that never says what the product does, or a fifteen minute engineering explanation that only an engineer will finish. Both fail for the same reason: nobody decided who the film is for, or which single question it has to answer.

Decide the question first

A technical product film can do one of four jobs well, and no film does all four.

• What is it? For someone who has never heard of the category. Ninety seconds, plain language, one clear demonstration.
• How does it work? For a technically literate buyer evaluating you. Longer, detailed, unhurried, and the one most worth making properly.
• Does it actually work? Evidence. Testing, installation, use in real conditions, ideally with a customer saying so in their own words.
• How do I use it? Support material, which quietly reduces the load on your team and keeps earning attention for years.

Pick one per film. A business with all four, made cheaply and clearly, is far better served than one with a single expensive piece attempting all of them.

If the film cannot be summarised in one sentence that names a buyer and a question, it will not answer either.

Showing something that is hard to see

Much technical work resists filming: it happens underwater, inside a machine, at a scale the eye cannot resolve, or over months. The answer is rarely animation alone, which people discount as an illustration of a claim. It is usually a combination.

• The real thing filmed as closely as possible, including the texture and the mess of actual conditions.
• A simple visual comparison. Treated against untreated, before against after, one side against the other, shot identically.
• Animation used only to reveal what genuinely cannot be seen, and clearly presented as a diagram rather than as footage.
• A person who understands it, explaining in their own words. Engineers are usually better on camera than marketing people expect, precisely because they do not perform.

Work I have directed for a marine coatings business turned on exactly that logic: the product's value is invisible until you put treated and untreated surfaces side by side under water, and the film's job was to make the comparison legible rather than to dress it up.

Language, and the translation problem

Technical companies write for people who already agree with them. The buyer is often a procurement lead, an operations director or an investor who needs the value in one sentence before they will tolerate the detail. Write both: the plain sentence at the top, the specification underneath, and never make the reader choose between being patronised and being lost.

This is also what search and AI answers reward. A page that says clearly what a product is, what it replaces and what it costs to run will be quoted. A page of positioning language will not, because there is nothing in it to quote.

Where it goes

The product page first, with the film embedded and the plain description above it. Then the sales team, who will use a two minute demonstration in meetings far more readily than a brochure. Then LinkedIn and, if the product is demonstrable, YouTube, where technical search keeps working long after a campaign has ended. Trade press will often take a genuinely clear explainer film as editorial, which is worth more than the equivalent advertising.

Common questions

How do you explain a technical product on film?

Decide the single question it answers: what is it, how does it work, does it work, or how do I use it. One film per question, in plain language, with a real demonstration.

Is animation a good way to show technical products?

Only for what genuinely cannot be filmed, and it should look like a diagram rather than footage. Buyers discount animation as an illustration of a claim rather than proof of one.

How long should a product film be?

Ninety seconds for the introduction, longer for a technical explanation aimed at an evaluating buyer. Length follows the question, not a rule.

Should engineers appear on camera?

Usually yes. They explain the work with a precision marketing language cannot fake, and buyers trust it because it does not sound performed.
