# unsupportedCaptureOutputClasses

The list of capture output subclasses not allowed for capture with this format, if any.

## Declaration

```swift
var unsupportedCaptureOutputClasses: [AnyClass] { get }
```

## Discussion

Discussion As a rule, capture formats with a given mediaType are available for use with all AVCaptureOutput subclasses that accept that media type. However, this isn’t always the case. For example, formats for high-resolution photo capture may not support the AVCaptureMovieFileOutput class due to bandwidth limitations.
