Black Video CAAnimation and AVFoundation AVAssetExportSession

Question

I\'m a relative newbie on the whole AVFoundation video editing circuit.

My current test app is a two screen application, the first screen does an AVFoundation Video

Answer 1

But if the size of the video wont be 320X480, it will mess up. Try to use this one to get the video size.

        CGSize videoSize = [[[self.videoAsset tracksWithMediaType:AVMediaTypeVideo] objectAtIndex:0] naturalSize];
