This application provides an easy way to import, edit, and share your movies. iMovie 4.0.1 includes improved performance and reliability for iMovie 4. This update provides increased performance when working with large projects, such as editing video clips and audio volume. iMovie 4.0.1 provides increased reliability when the application opens, when titles are added to the timeline, and with 3rd party plug-ins that are removed or no longer available to an iMovie project (for example, when you open a project on a different computer). Other improvements include fixes for pixelated video, corrupted Ken Burns clips, and loss of audio, which could occur after editing video or audio and then emptying the trash.
