# captureDeltaTimeRational

> Slows your application’s playback time to allow Unity to save screenshots in between frames.

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine](/engine/6000.5/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
public static RationalTime captureDeltaTimeRational { get; set; }
```

### Remarks

Same as captureDeltaTime but using a RationalTime representation. The returned timeAsRational shares the same discretization increment value (TicksPerSecond). Setting it to a value of 0 or invalid restores the normal Unity time management.
