# Media — Progress

The LiSA Player regularly sends a media progress message to report the current playback status and track visitor dwell time.

### Properties

Along with all standard [Media Message properties](/developers/guides/player-communication/message-api-reference/media.md#properties), a **Progress** message includes the following additional properties:

<table><thead><tr><th width="243" valign="top">Name</th><th width="192" valign="top">Type</th><th valign="top">Description</th></tr></thead><tbody><tr><td valign="top"><code>messageType</code></td><td valign="top"><pre><code>Literal
</code></pre><p>Required.</p></td><td valign="top"><code>lsc:media:progress</code></td></tr></tbody></table>

### Legacy Properties

{% hint style="warning" %}
If your integration uses **LiSA Player Version 1**, none of the properties described above will be available.

For **LiSA Player Version 2**, legacy properties can be ignored.
