# VideoTimeUpdateMode

> Defines the time source the VideoPlayer uses to update the timing of the video playback.

## Definition

* **Type:** Enum
* **Namespace:** [UnityEngine.Video](/engine/6000.0/script-reference/unityengine/video.md)
* **Assembly:** UnityEngine.VideoModule

```csharp
public enum VideoTimeUpdateMode
```

## Remarks

Use these settings to synchronize your video with audio, gameplay scaled time or unscaled time.

## Examples

```csharp
// This script switches between the time update modes when you press the Spacebar.
// It also creates a slider that you can use to change the timescale of the game. 
// The changes are visible on your video when you enter the GameTime time update mode.

// To set up your project for this script: 
// 1. Attach this script to a GameObject in your Scene. 
// 2. Add a VideoPlayer component to your GameObject.
// 3. Assign a VideoClip to your VideoPlayer.
