# Invalid

> Invalid time value.

## Definition

* **Type:** Field
* **Namespace:** [UnityEditor.Media](/engine/6000.6/script-reference/unityeditor/media.md)
* **Assembly:** UnityEditor

```csharp
public static readonly MediaTime Invalid
```

### Remarks

Invalid time values have an invalid rate (see [MediaRational.isValid](/engine/6000.6/script-reference/unityeditor/media/mediarational/isvalid.md)), regardless of the [MediaTime.count](/engine/6000.6/script-reference/unityeditor/media/mediatime/count.md) value. This utility value just provides one of the many possible invalid [MediaTime](/engine/6000.6/script-reference/unityeditor/media/mediatime.md)s.
