# minFrameDuration

The minimum frame duration.

## Declaration

```occ
@property (nonatomic) CMTime minFrameDuration;
```

## Discussion

Discussion This property specifies the minimum duration of each video frame produced by the video data output, placing a lower bound on the amount of time that should separate consecutive frames. This is equivalent to the inverse of the maximum frame rate. A value of zero or invalid indicates an unlimited maximum frame rate. The default value is invalid.
