muddoug said: When I just need to rotate a video, I use Quicktime Pro ($29.95) on my Mac. You should be able to rotate the video in any video editor. The problem will be trying to fit the rotated frame into the horizontal video frame. Shooting with the camera on it's side seems like a good idea, until you have to fit the video back into a standard video frame size. I've done it with green screened video where the vertical subject was going to be overlaid onto a horizontal background and I wanted as much resolution as I could get for chroma-keying. Another time I did it, I ended up doing a pan/scan edit over the rotated video.

Anyway, all you want is a 2D transformation. It is so mathematically trivial, just about any editing software should have some kind of transformation or rotation feature.

Warm regards,
