# Video player metrics

> Video player metrics cover engagement, average view duration, viewer counts, audience browsers, geography, hosts, and operating systems.

Player metrics are collected only from the Gcore built-in player. Each video keeps its own charts on the video settings page.

## Player metrics for a video

Open the video, then read the charts on the **Player metrics** tab.

**1. Open the video list**

In the [Gcore Customer Portal](https://portal.gcore.com), navigate to **Streaming** > **Video Hosting** > **All videos**.

**2. Open video settings**

In the video list, click the video name, or open the three-dot menu and click **Settings**.

**3. Select player metrics**

On the video settings page, select the **Player metrics** tab.

Use the date range, time zone, and **Auto refresh** controls above the charts to change the view. The default range is the last 24 hours, auto refresh is off or every 30 seconds or 1, 2, 3, 4, or 5 minutes, and the time zone is UTC or local time.

## Engagement

Engagement charts show how far viewers get through the video and how many of them there are.

### Average view duration

Despite the name, this chart shows how many viewers remain at each point in the video timeline. A drop marks where viewers left before the video ended.

### Amount of viewers

The **Amount of viewers** chart shows four metrics over the selected date range:

* **Uploads** counts how many times the player was opened. It does not mean file uploads.
* **Starts** counts how many times playback was started.
* **Viewers** counts viewers who watched for at least 5 seconds.
* **Unique viewers** counts distinct viewers by IP address, screen size, browser, and cookies.

## Audience

Audience charts show where viewers are and which browser, page, and operating system they use.

### Browsers

Browser name and version each get a separate bar, so two releases of the same browser stay apart.

### Geography

A country is included after playback lasts at least 5 seconds. The country comes from the viewer IP address.

### Hosts

Page URLs are included only when the view is longer than 5 seconds. The host `streaming.gcore.com` means the video was watched from a personal Gcore account.

### Operating systems

Desktop and mobile systems share the **OS** chart, and this breakdown is separate from browsers.
