I was recently asked to rotate a video for a friend. Video rotation is required every now and then (especially when you record using a photo camera and the orientation is wrong).
It's surprisingly easy, but very well tucked away inside of QuickTime. Here are the steps:
- Open movie in QuickTime.
- Window -> Show Movie Properties (J)
- In the track listings select the video track (you'll know because 'Visual Settings' will become available as a tab)
- Select Visual Settings and from the Flip/Rotate options, rotate in the appropriate direction.
Then just save it, or export it to the format du jour.
