```
func startVideoCapture() -> Bool
```

## Return Value

<doc://com.apple.documentation/documentation/Swift/true> on success or <doc://com.apple.documentation/documentation/Swift/false> on failure. This method may return a value of <doc://com.apple.documentation/documentation/Swift/false> for various reasons, among them the following:

- Movie capture is already in progress
- The device does not support movie capture
- The device is out of disk space

## Discussion

Use this method in conjunction with a custom overlay view to initiate the programmatic capture of a movie. You can take more than one movie without leaving the interface, but to do so requires you to hide the default image picker controls.

Calling this method while a movie is being captured has no effect. You must call the [`stopVideoCapture()`](/documentation/UIKit/UIImagePickerController/stopVideoCapture()) method, and then wait until the associated delegate object receives an [`imagePickerController(_:didFinishPickingMediaWithInfo:)`](/documentation/UIKit/UIImagePickerControllerDelegate/imagePickerController(_:didFinishPickingMediaWithInfo:)) message, before you can capture another movie.

Calling this method when the source type of the image picker is set to a value other than [`UIImagePickerController.SourceType.camera`](/documentation/UIKit/UIImagePickerController/SourceType-swift.enum/camera) results in the throwing of an <doc://com.apple.documentation/documentation/Foundation/NSExceptionName/invalidArgumentException> exception.

If you require additional options or more control over movie capture, use the movie capture methods in the AVFoundation framework. Refer to <doc://com.apple.documentation/documentation/AVFoundation>.
