# timescale

The time scale of the movie.

## Declaration

```swift
var timescale: CMTimeScale { get set }
```

## Discussion

Discussion The default movie time scale is 600. In certain cases, you may want to set this to a different value. For example, a movie that contains a single audio track should set the movie time scale to the media time scale of that track. Set the value of this property on a new empty movie before you perform any edits on it.
