  "chat": "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."
