Fix portrait iPhone videos with iMovie
The iPhone’s ability to shoot video in any orientation is great, but it can be annoying when you realise you accidentally shot a video in portrait when you would prefer the more conventional landscape orientation. Generally there are two common scenarios: The first is where you shot an entire video in portrait, and secondly where you quickly realise and rotate the phone back to landscape for the majority of the video. Here’s how to fix videos in both these situations.
First lets consider the situation where you started filming in portrait, then quickly realised and rotated the phone to film the rest of the video in landscape. The problem with this is the iphone decides the orientation of the video at the start, meaning that after you rotate the phone the video stays in portrait and everything just becomes sideways.
Fixing this is simply a case of rotating the video 90 degrees to the correct orientation. In iMovie, start by selecting the portion of the clip that you want to rotate. This might be as simple as just selecting the entire clip, but if you rotated the phone multiple times during the video you will want to select each portion separately.
Next, click the crop button, located near the middle of the centre bar, as shown below.
Once you click the crop button, some new controls should appear over the top of the viewing window. The ones we’re interested in are the curved rotation arrows. Simply click the one that corresponds to the direction you want to rotate the video, then click the Done button.
This leaves you free to export your Movie from iTunes using one of the options in the Share menu. It’s really easy to export it straight to YouTube, Facebook or MobileMe or you can just export it back to a movie file to use however you want.
Now lets consider the situation where you have an entire video shot in portrait orientation. Obviously there’s no magic way to convert this into a nice looking landscape video, but we can do our best by cropping and adding black bars down the side. This will allow us to export to a standard landscape HD video, meaning there is no danger of getting a stretched video when uploading on online video sites like YouTube.
As before, start by clicking the crop button on the centre bar to bring up the controls over the viewer. On these controls, click the button that says “Crop”, and then click the button that says “Allow Black.” Now you can adjust the size and position of the green box to choose the new dimensions of your video. Before you click Done, it’s worth clicking the play button to check that you haven’t accidentally cropped something important out of the video.
To finish up, choose “Export Movie” from the Share menu. You can choose any quality, but HD 720p (1280 x 720) will preserve the original quality as much as possible.
