Speaker-labelled captions

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 speaker-labelled captions: a muted viewer can tell who is talking. How it works: a small name tag above each caption line, one colour per speaker, the spoken word in a highlighted pill. It is right for: dialogue, interviews, any two-voice format. In the measured two-voice reference 243 of the visual changes sit in the caption band, against 49 in the call tiles and 46 in the shared screen. Be concrete: numbers, seconds and settings, no theory. Ask me one question first if something you need is missing.
