# Recording a session

> Start a capture session and understand the modality controls.

## Starting a session

From the Holos Capture home screen:

1. Tap **New Capture** to open the session setup sheet
2. Select a **Skill** to record under, or leave it unassigned for a free-form capture
3. Confirm that tracked objects are loaded (if any are configured for the skill)
4. Tap **Start Recording**

The app enters an immersive space and begins recording all active modalities simultaneously.

## Modalities

Each modality captures a distinct data stream. All streams are timestamped and synchronized to the same clock.

| Modality        | Notes                                                                                             |
| --------------- | ------------------------------------------------------------------------------------------------- |
| Stereo video    | Always active. Records left and right camera at 1080p.                                            |
| Device pose     | Always active. Records headset position and orientation at full frame rate.                       |
| Hand tracking   | Active when hands are in frame. Records full joint skeleton for both hands.                       |
| Object tracking | Active only for objects configured on the skill. See [Tracked objects](/capture/tracked-objects). |
| Transcription   | On-device speech recognition. Produces timestamped transcript segments.                           |
| Location        | Recorded once at session start.                                                                   |

## During a session

* A recording indicator is visible in the corner of your view while capturing
* Tracked objects appear highlighted when the system has a lock on them
* Transcription happens in real time; speak clearly if you want good captions

## Stopping a session

Tap the **Stop** button to end the recording. The app will finalize all streams and package them into a session file. This may take a few seconds for longer recordings.

Once finalized, you'll be taken to the session review screen. See [Uploading](/capture/uploading).

## Tips for good captures

See the full [Tips for good captures](/capture/tips) guide for detailed guidance on environment setup, movement, narration, object tracking, and common mistakes to avoid.
