# Video Composer

## What Is Video Composer

Video Composer is a built-in AI agent for scoring video in ACE Studio. It analyzes your video frame by frame and scene by scene. Then it plans and generates matching soundtracks or sound effects as editable clips on the timeline.

## How to Use Video Composer

Video Composer works with the [Video Track](/project/arrangement-in-canvas/video-track.md).

Once you import a video onto the Canvas, the Video Monitor and agent chat box appear. You can then prompt the agent to generate music or sound effects for the whole video or a selected range.

### Import a Video

1. Drag your video file onto the Canvas.
2. ACE Studio places it on the Video Track automatically.
3. The Video Monitor will open automatically. Once closed, you can reopen it by either double-clicking a Video Clip or clicking the track header.

You can show or hide the [Video Track](/project/arrangement-in-canvas/video-track.md) from the track list header.

Use the [Mixer](/project/mixing/mixer.md) to mute, solo, or adjust the video audio volume.

If the video includes embedded audio, you can right-click the video clip to detach the audio. ACE Studio places the detached audio on an Audio Track for separate editing.

#### Generate Music and Sound Effects

1. Choose whether to generate music or sound effects.
2. Describe the mood, timing, style, or events you want.
3. Generate for a selected range, or leave nothing selected to use the full video.
4. Review, edit, and rearrange the generated clips on the timeline.
5. Keep chatting in the same session to refine earlier results or add new cues.

#### Manage Chat Sessions

Click the <kbd>+</kbd> icon to start a new session.

Click the <i class="fa-clock">:clock:</i> icon to reopen an earlier session.

Use a new session when you want a different creative direction.
