# Sound & music (https://getreely.co/docs/directing/sound)

> Add a music bed to a teaser, cut the video to the beat, and put sound effects on transitions.

Videos are silent unless you ask. Any video can carry a music bed — and once there is music, the cuts should land on it.

## A music bed

Give the agent a path to an audio file. It has to know the track **before** it times anything, because the tempo decides how long each scene is.

**Prompt:** `Use assets/track.m4a as the music bed.`

## Cutting to the beat

Reely measures the track — tempo, where the first beat lands, and where the drop is — and then times scenes in beats rather than seconds. Every cut lands on the music instead of near it.

| You want | Say |
| --- | --- |
| Cuts on the beat | “Cut every scene on the beat.” |
| The reveal on the drop | “Land the product reveal on the drop.” |
| Faster cutting | “Two beats per scene instead of four.” |
| The action on a beat | “Make the tap land on a beat.” |

> Bring your own licensed track. Reely does not supply music.

## Transition sound effects

Screen changes can carry a short effect — a **whoosh**, a **whip**, or a **ding**. Off unless you ask, because they date a video fast.

**Prompt:** `Add a whoosh on each screen transition.`

## Volume and ducking

- “Bring the music down — it is fighting the captions.”
- “Mute the music for the last scene.”
- “Fade the track out over the final two seconds.”
