# Coloured keyword in the caption

Edit / Edit effect / Captions. Checked 2026-11-13.

The viewer learns the one word that matters in each line, even with the sound off.

- Use when: Explainers that teach terms; any caption style that needs emphasis.
- Phrase: captions of about three words in white, the term being defined in the brand accent colour at the moment it is said

## Watch out

- Colour only the word being defined. In the measured product explainer a colour on any other word is a listed failure. (practitioner; Director Chair measurement of a published short, Oct 2026)
- Four of the nine measured references highlight one word per caption by colour. (measured; Director Chair measurements of published shorts (measured 22 and 23 Oct 2026))

## Prompts

### Any chat model

```
Give me an edit brief: where it goes on the timeline, the exact settings, and what to check before export, for a short video about [your product], for [your audience]. The technique is coloured keyword in the caption: the viewer learns the one word that matters in each line, even with the sound off. How it works: captions of about three words in white, the term being defined in the brand accent colour at the moment it is said. It is right for: explainers that teach terms; any caption style that needs emphasis. Colour only the word being defined. Four of the nine measured references highlight one word per caption by colour. Be concrete: numbers, seconds and settings, no theory. Ask me one question first if something you need is missing.
