Hi everyone I'm using iMovie HD to create some sort of video montage of my last vacation. But there seems to be a glitch with the Fast/Slow/Reverse video effect (all other effects work fine). I adjust the slider to a desired speed, and when I click apply, the red rendering bar starts to fill, but after it fills up, the clip reverts back to its original state (including volume level -- I initially had the volume to 0%). If anyone can help me ASAP that would be terrific. Thx P.S. In case it's useful info, I'm using a 2 GHz MacBook (w/ 60GB Hard Drive).
