Once you've got a frame extracted from the video file, DO NOT alter it in any way. This means: no resize, no rotate, etc... Feed Autopano with it, and let it do the work. Also note that it doesn't matter if video frame has not the same dimensions as photographs to be stitched. If you did record video in portrait mode, you will be able to rotate it in 3rd screen.
