UIVideoEditorController lost video resolution

Question

I am trying to use UIVideoEditorController to edit my video, but it seems to lose my video resolution. My original video was 720 x 1280, but after using the UIVideoEditorController, the quality becomes 360 x 640.

I tried to set the videoQuality to be UIImagePickerControllerQualityTypeHigh or even UIImagePickerControllerQualityTypeIFrame1280x720, but that doesn't help.

I am working on the iPad and here are my code:

self.editorController = [[[UIVideoEditorController alloc] init] autorelease];
self.editorController.videoPath = self.tempVideoPath;
self.editorController.delegate = self;
self.editorController.videoQuality = UIImagePickerControllerQualityTypeHigh;

CKLog(@"%d", self.editorController.videoQuality);

self.popOverController = [[[UIPopoverController alloc] initWithContentViewController:self.editorController] autorelease];
self.popOverController.delegate = self;
self.popOverController.popoverContentSize = CGSizeMake(700, 700);
[self.popOverController presentPopoverFromRect:CGRectMake(0, 0, 1, 1) inView:self.videoView permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];

Answer 1

According to the UIVideoEditorController documentation:

A UIVideoEditorController object, or video editor, manages the system-supplied user interface for trimming video frames from the start and end of a previously recorded movie as well as reencoding to lower quality...

The UIVideoEditorController class has a property called videoQuality. It allows us to choose the video quality when saving the trimmed video. (The default value is UIImagePickerControllerQualityTypeLow)

UIImagePickerControllerQualityTypeHigh uses the highest-quality video recording supported for the active camera on the device. It looks much better, but still seems to lose a little of the original resolution.
