Save video in video app?

Can I take the video embedded in the application and save it in the camera frame? If so, how? Is this the same property of UIWriteImage?

You can try this code, assuming you already know how to save the image:

-(void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
    if([mediaType isEqualToString:(NSString *)kUTTypeMovie]) {
       //Save the video
       NSURL *movieUrl = [info objectForKey:UIImagePickerControllerMediaURL];
       UISaveVideoAtPathToSavedPhotosAlbum([movieUrl relativePath], self,@selector(movie:didFinishSavingWithError:contextInfo:), nil);
    }
}

Or you could try:

-(void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
  if([mediaType isEqualToString:(NSString *)kUTTypeMovie]) {
    NSURL *movieUrl = [info objectForKey:UIImagePickerControllerMediaURL];
    ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
    [library writeVideoAtPathToSavedPhotosAlbum:movieUrl completionBlock:^(NSURL *assetURL, NSError *error){
        if(error) {
            NSLog(@"CameraViewController: Error on saving movie : %@ {imagePickerController}", error);
        }
        else {
            NSLog(@"URL: %@", assetURL);
        }
    }];
  }
}

For iOS 8 and above, use PHPhotoLibrary . ALAssetsLibrary is deprecated.

Include:

@import PhotosUI;

And then use this to save your movie:

[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^
 {
     [PHAssetChangeRequest creationRequestForAssetFromVideoAtFileURL:<%Your Movie URL%>];
 }
                                  completionHandler:^(BOOL success, NSError *error)
 {
     if (success) {
         NSLog(@"Movie saved to camera roll.");
     }
     else {
         NSLog(@"Could not save movie to camera roll. Error: %@", error);
     }
 }];
