    [mySLComposerSheet setCompletionHandler:^(SLComposeViewControllerResult result) {

        switch (result) {
            case SLComposeViewControllerResultCancelled:

                break;
            case SLComposeViewControllerResultDone:
                NSLog(@"Post Sucessful");

Take a look at the MPMoviePlayerController class. If I remember correctly the requestThumbnailImagesAtTimes() method will return thumbnail images X seconds into the file (you specify how many seconds into the file you want it to perform the capture).

If nothing else, it might point you in the right direction if it turns out it won't work for your particular needs.
