  "chat": "Give me a sound brief: what to record or pick, where it sits on the timeline, the levels, and what to check before export, for a short video about [your product], for [your audience]. The technique is one clock for picture and sound: every sound lands on its frame, and stays there when the edit is re-timed. How it works: one list of event times drives the animation, the key presses and the sound cues. It is right for: code-rendered video with typing, counters or many cues. In a 59-second 3D film one file holds the time of all 50 typed characters. Name each sound cue by its event, not by a time, and print every cue's offset from its beat: more than one frame is a bug. Be concrete: numbers, seconds and settings, no theory. Ask me one question first if something you need is missing."
