Hello.

 

I've tried to create a movie in imovie 11 and wanted to speed up a short part (more or less 10 seconds). But when I try the function, my preview windows is just grey and I can't edit the video at all after (it always says that I have to select a video part before editing but I cant select it anymore). I have to restart imovie and delete the speeded up part so that I can continue with editing. I've found out that neither speed up nor slow down functions are working. Any tips what could occur the problem?

 

I've got a Macbook Pro Retina Mid 2012 so the hardware shouldn't be the problem. And also my Operating system is up to date with Mountain Lion 10.8.2.

    Can you right-click on one of the clips you are trying to speed up? Then choose Reveal In Finder.

    In the Finder, right click on this same clip, and choose OPEN WITH.../QuickTime Player.

    In QuickTime Player, hold down the command key while typing the letter i.

    That should bring up the inspector.

    Tell us the dimensions of your clip and everything you see next to the word FORMAT:

    Have you tried optimizing your clips?

     

    Right-click on either an Event Clip or on an Event Name and see if it offers to optimize.
