You can use the free REVERSE plug-in from Klaus Horst (KHTvReverse1.zip 1).
Look HERE to see where you can download it and how to install.
I've been editing some footage of my girlfriend wakeboarding.
She has asked me if I can change some parts of the footage (usually the big jumps or frightening falls) to slow motion.
I've only got studio 9 basic.
Much appreciation in advance
