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?
