  "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 punch-in: a tighter crop on a line says this part matters. How it works: punch in to 1.12 times on every other sentence, the face staying at the same height in the frame. It is right for: face cam, on a key sentence or on every other segment. Punch-ins soften a 1080 pixel take. Two of our four starter styles use a light punch-in on every other segment; the fast one was measured from a clip at 6.8 changes per 10 seconds. Be concrete: numbers, seconds and settings, no theory. Ask me one question first if something you need is missing."
