Hi Damon,

Sorry you're feeling frustrated, but please do have some patience. We try to be as responsive as possible on the Forum, and we get an awful lot of help from students, but it does take us time to work through issues, especially over the weekend when the Treehouse staff is off. :)

Anyhow, I'm assuming you're on iOS 7, where the thumbnailImageAtTime:timeOption: method we covered in the video has since been deprecated, meaning that it may not work from iOS 7 onward. The best workaround I've found is listed in the Teacher's Notes section on that video page. It's a link to a suggestion on StackOverflow. Let us know if that helps or if you need further assistance.

So this:

AVURLAsset *asset1 = [[AVURLAsset alloc] initWithURL:partOneUrl options:nil]; AVAssetImageGenerator *generate1 = [[AVAssetImageGenerator alloc] initWithAsset:asset1]; generate1.appliesPreferredTrackTransform = YES; NSError *err = NULL; CMTime time = CMTimeMake(1, 2); CGImageRef oneRef = [generate1 copyCGImageAtTime:time actualTime:NULL error:&err]; UIImage *one = [[UIImage alloc] initWithCGImage:oneRef]; [_firstImage setImage:one]; _firstImage.contentMode = UIViewContentModeScaleAspectFit;

should be its own method ok, do you show how to get the partOneUrl as an NSURL in one of the tutorials but then dont you have to use PFFile then turn that from a PFQuery to an PFFile then to NSURL or how is the process because i looked at parse.com but im not getting anywhere with them and their documentation, oh also is there a book you recommend for me to read for iphone development
