# Recording Limits & Duration

> Default recording duration, maximum file sizes, and supported video formats

Userplane enforces limits on recording duration and file size to ensure reliable capture and playback.

## Recording duration

The default maximum recording duration is **3 minutes** (180 seconds). When a customer reaches the time limit, the recording stops automatically.

The minimum recording duration is **1 second**. Recordings shorter than this are discarded.

## File size limits

| Resource        | Maximum size |
| --------------- | ------------ |
| Video recording | **500 MB**   |
| Audio recording | 50 MB        |
| Thumbnail       | 10 MB        |
| Console logs    | 50 MB        |
| Company logo    | 4 MB         |

## Supported video codecs

Recordings use the best codec available in the customer's browser. Userplane supports the following codecs in priority order:

| Codec     | Notes                                                          |
| --------- | -------------------------------------------------------------- |
| **AV1**   | Best compression, \~30% smaller than VP9. Used when available. |
| **VP9**   | Excellent compression, widely supported.                       |
| **H.264** | Hardware-accelerated, best Safari support.                     |
| **VP8**   | Good compatibility, used as a fallback.                        |

Recordings are captured in **WebM** or **MP4** containers depending on browser support.

## Supported thumbnail formats

Thumbnails are captured as PNG, JPEG, or WebP images.

## Audio capture

When voice and device audio capture is enabled in your [domain recording preferences](/recording-links/domain-preferences), Userplane records the user's microphone input and system audio alongside the screen video. The audio track is stored separately and played back in sync with the video in the recording detail view.
