How do I rotate a movie on the iPad/iPhone? I have a movie in my camera roll that is incorrectly rotated.  I would like to rotate it 90 degrees to fix the problem.

Using this tip I was able to rotate the movie using iMovie.

However, the problem is that the movie is now cropped incorrectly.  The movie is stuck in a landscape orientation instead of a portrait orientation, so that the bottom part of the movie is now cut off.



How can I rotate a movie in iOS while preserving its proper aspect ratio and dimensions?
I don't have any experience with this app but it seems like it will do what you are after: https://itunes.apple.com/us/app/video-rotate-free/id626614962?mt=8
