Apple has released iMovie 4.0.1, a minor update to its entry-level video editing application.

The update offers improved performance and makes the application more reliable, says Apple. It is a 1.2MB download, available in multiple languages.

Notes accompanying the release state: "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 third-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)."

The notes confirm the that update "includes 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".
