Key question

What happens in the first three seconds?

Short-form videos are the most powerful format for reach, and the most demanding. People decide in seconds whether to stay. A clear structure, a strong hook, and clean subtitles make all the difference, not expensive equipment.

Learning objective: You will be able to structure a short video into a hook, content and call to action, formulate a hook, and produce a video using simple resources.

The first three seconds are decisive.

4.1 / Structure of a short video

Hook, content, call to action.

Almost every successful short video follows a simple arc. It helps with planning, filming, and editing.

01

Hook

The first three seconds. An image or phrase that makes people stay.

02

Content

A thought, shown rather than told. Quick cuts, clear steps.

03

Prompt

What should you do? Save, follow, book a course.

One video, one idea. If you have two messages, make two videos.

One video, one thought.

4.2 / The Hook

The beginning is what matters.

The hook is the promise of the video. It can be a question, a number, a mistake, a surprising image, or a before-and-after. It needs to work without sound, as many watch on mute.

Image and text work together: something happens in the first second, while the key message appears simultaneously as short on-screen text, kept within the safe zone.

Understandable without sound.

4.3 / Low-budget production

Lighting, sound, subtitles.

A mobile phone is all you need to make good short videos. Front lighting, clear sound and a stable picture are more important than the camera. A small clip-on microphone will do more to improve quality than any new camera.

Subtitles are essential: they make videos understandable without sound and accessible to people with hearing impairments. Always check automatically generated subtitles, especially for technical terms and names.

Lighting and sound over technology.

Exercise

A reel in three parts

Task: Plan and produce a reel of no more than 30 seconds for Atelier Lumen.

STEP 1

Draft three hooks using different patterns and choose the strongest one.

STEP 2

Draw a six-panel storyboard: hook, four steps, call to action.

STEP 3

Film on your mobile in daylight and edit down to a maximum of 30 seconds.

STEP 4

Add subtitles and check the safe zone.

Analysis: Do viewers understand the video without sound? Do they stay engaged after three seconds?
