# Natural sound under B-roll

Edit / Sound / Music and mix. Checked 2026-11-13.

The cutaway feels real because it sounds like the place.

- Use when: Filmed B-roll of hands, tools, machines, rooms.
- Phrase: keep the brush on the panel audible under the shot, and record 30 seconds of the room on its own

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 natural sound under B-roll: the cutaway feels real because it sounds like the place. How it works: keep the brush on the panel audible under the shot, and record 30 seconds of the room on its own. It is right for: filmed B-roll of hands, tools, machines, rooms. Natural sound under B-roll often sells the cut better than music. Be concrete: numbers, seconds and settings, no theory. Ask me one question first if something you need is missing.
