I need to rotate a MP4 video by 90 degrees. There is software like Free Video Flip and Rotate available that does this but produces an AVI file.
Do you have any suggestions for a software to produce a MP4 that is in the same quality (and file size) as the original, just 90 degrees rotated? Does not have to be free software ;-)
