# videoMinFrameDuration

The smallest time interval the connection can apply between consecutive video frames.

## Declaration

```swift
var videoMinFrameDuration: CMTime { get set }
```

## Discussion

Discussion When isVideoMinFrameDurationSupported is true, the value of the property configures the lower bound for the amount of time a video connection separates consecutive frames. The value is equivalent to the reciprocal of the minimum frame rate. You can set an unlimited frame rate with zero or invalid (which is the default).
