You want to use the kCVPixelFormatType_420YpCbCr8BiPlanarFullRange format.

adding this to your videooutput

OSType format = kCVPixelFormatType_420YpCbCr8BiPlanarFullRange;

    videoOutput.videoSettings = [NSDictionary dictionaryWithObject:[NSNumber 
                                                                    numberWithUnsignedInt:format]
                                                            forKey:(id) kCVPixelBufferPixelFormatTypeKey];

and following this to convert the Y plane to grayscale to images:

AVFoundation - Get grayscale image from Y plane (kCVPixelFormatType_420YpCbCr8BiPlanarFullRange)

or if you want to save it as video:
