How do I get NSData from a video url?

Question

I'm trying to get video from a UIImagePicker and send it as data across my restkit API.

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
        let videoURL = info["UIImagePickerControllerReferenceURL"] as? NSURL

var movieData: NSData?
        do {
            movieData = try NSData(contentsOfURL: videoPath, options: .DataReadingMappedIfSafe)
        } catch {
            print(error)
            movieData = nil
            return
        }

// Multipart Form Request for RestKit POST goes here

        imagePickerController.dismissViewControllerAnimated(true, completion: nil)
    }

Getting the following error:

Error Domain=NSCocoaErrorDomain Code=256 "The file “asset.MOV” couldn’t be opened." UserInfo={NSURL=assets-library://asset/asset.MOV?id=B906AB1B-F311-47BA-8FE9-EE7AADDB7796&ext=MOV}

    func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
            let videoURL = info["UIImagePickerControllerMediaURL"] as? NSURL
             do {
                let video = try NSData(contentsOfURL: videoPath, options: .DataReadingMappedIfSafe)
             } catch {
                print(error)
                return
             }
            imagePickerController.dismissViewControllerAnimated(true, completion: nil)
    }
