If you own one of Apple's latest laptops, your version of Mac OS X may not have shipped with journaling turned on (you can check by launching Disk Utility, selecting your boot volume name, and looking at the Format line in the disk information area at the bottom of the window). Journaling is a system-level feature that causes the system to log all disk changes in order to prevent data loss in the event of a crash or power outage. (When you erase a Mac volume under Panther or Tiger, the recommended option is to format it as "Mac OS Extended (Journaled)".) To remedy this situation, Apple has released MacBook, MacBook Pro Software Update 1.0, a 200K download that applies to MacBook (13-inch Mid 2007) and MacBook Pro (2.2/2.4 GHz Mid 2007) models. After you install the update, Apple recommends running Disk Utility from another startup disk (such as the Mac OS X Install or Restore disc) and performing a disk verification.
iMovie '09: Speed Clips up to 2,000%
iMovie '09 brings back the capability to speed up or slow down clips, which went missing in iMovie '08. Select a clip and bring up the Clip Inspector by double-clicking the clip, clicking the Inspector button on the toolbar, or pressing the I key. Just as with its last appearance in iMovie HD 6, you can move a slider to make the video play back slower or faster (indicated by a turtle or hare icon).
You can also enter a value into the text field to the right of the slider, and this is where things get interesting. You're not limited to the tick mark values on the slider, so you can set the speed to be 118% of normal if you want. The field below that tells you the clip's changed duration.
But you can also exceed the boundaries of the speed slider. Enter any number between 5% and 2000%, then click Done.
