I'm using UIImagePickerController to allow my user to select a video from the asset library.

When the user selects the "Choose" button on the second screen, the view displays a progress bar and a "Compressing Video..." message.

Why is this happening?

Is there some way I can avoid this compression operation?

Answer: There is currently no way to control how UIImagePickerController compresses the picked video.

I just did some quick tests. Using a test app I created, I picked the same video two times -- once with the videoQuality property set to UIImagePickerControllerQualityTypeHigh and once with it set to UIImagePickerControllerQualityTypeLow. The resulting files that were copied over are exactly the same size, 15.1MB with a frame size of 360x480. The original was 72.5MB with a frame size of 480x640. Apparently this property doesn't affect the compression used at all.
