An advertising spot is a short piece of fixed duration, made to fill paid space: a TV slot, a YouTube pre-roll, a digital billboard, a radio break. That condition — space bought by the second — is what defines everything else.
How it differs from a corporate video
A corporate video lives on your website or in a sales meeting: the viewer has already decided to pay attention and it can run two minutes. A spot, by contrast, interrupts somebody who was doing something else. That is why a spot carries a single idea, while a corporate video can develop several. Cramming three messages into thirty seconds is the most common way to communicate none of them.
The standard durations and why they exist
They are not arbitrary: they match how advertising space is sold. The most used are 5, 10, 15, 20, 30, 45 and 60 seconds. In practice:
- 5 and 6 seconds. The bumper format, unskippable. Only enough for one image and a brand.
- 15 seconds. The social and pre-roll standard. One idea, one benefit, a close.
- 30 seconds. The television classic. Room for a small story with setup and resolution.
- 45 and 60 seconds. For launch or institutional campaigns, where there is budget to buy more air.
The usual approach is to produce the long version and derive the 15 and 6 second cuts from it, but that gets planned in the script: a badly structured 30-second spot cannot be cut to 15 without losing its meaning.
Types of spot that work
- Problem-solution. The most used and most reliable: show a concrete annoyance, the product solves it.
- Demonstration. The product in use, showing what it does. Essential when the benefit is visible.
- Testimonial. Real customers or staff talking. The most trust-building and the cheapest to produce.
- Emotional. Tells a story with the brand appearing at the end. Needs good execution; done badly, nobody remembers who was advertising.
- Humour. Very effective for recall, very risky for brand image.
- Animated. Solves what cannot be filmed and lets you change language without reshooting.
- Institutional or campaign. Does not sell a product: it positions an idea or a behaviour. The territory of government and NGOs.
How a 30-second spot is structured
A split that works: the first 3 seconds to stop the scroll or the attention, around 20 seconds to develop the single idea, and the final 7 for the brand and the action you expect. One neglected detail: the ending has to work with the sound off too, because on social a large share of the audience never turns it on.
What makes a spot expensive
Not the duration, but what appears on screen: professional actors, locations, art direction, original music and animation. On top of that comes something many companies discover late: talent and music contracts have a term and a territory. A spot can become legally unusable the following year if the rights were not renewed, even though the file is still on the server. Always ask for how long and in which media you may run what you are paying for.
