Recently, when trying to export movie files from QuickTime Pro (7.0.4) or iMovie HD (6.0.1), I’ve been getting mysterious errors. This unhelpful iMovie one popped up when I tried to export an MPEG-4 project using the QuickTime Full Quality setting:
Other formats failed as well. For example, trying to export in iPod video format ended with this unhappy message:
Strangely, I was able to export the project to iDVD and burn a disc. Perhaps the original iMovie project was corrupt, because a new test movie exported correctly.
Well, scratch that: The files exported, but the cross-dissolve transitions were hosed. Instead of fading smoothly between scenes, the movie just went black for the duration of the crossfade. Anyone else run into this?
[UPDATE, 2006-04-24: I created a new MP4 project today and got the same dropouts during transitions. So I started over in the DV format, using the same clips. This time, the transitions worked properly.]
I had more luck overcoming the QuickTime Pro errors. For a while, every time I tried to export something, the progress bar would grow for a while, then cough up this wall:
I discovered that copying the movie into a new one (Command-A, Command-C, Command N, Command-V) produced a document that would allow export. Uninstalling the Flip4Mac software from my Mac—a 2.3GHz dual G5 running OS 10.4.6—and restarting seemed to restore normal exporting behavior. (More on that apparent conflict here.)
I’ll cover more surprising QuickTime discoveries in a future blog, but I’m curious if you’ve encountered iMovie glitches as well, and if so, how you’ve solved them.
