I can get the very currecnt QT-Pro to invert, flip and change 90deg CW or CCW ...but when I Google 'rotate in QT' ...there are instructions that show an interface that allows you to manually change the horizon - maybe an old version of QT?
I've mounted a waterproof cam on a kitesurfing board and, lucky me: 90deg never works. iMovie plugins seem to have the same limitations. Any thoughts?
