Apple has updated iMovie, bringing its popular iLife application up to version 3.0.3.

The company says iMovie 3.0.3 provides: "Improved performance and stability for iMovie 3, especially on G3 processor Macs, for rendering, audio and the Ken Burns Effect."

Refinements to the Ken Burns Effect allow greater pan-&-zoom control on digital images, and make it easier to crop digital stills. QuickTime 6.3 is required for improvements to audio sync and audio integrity.

The update is available for download from Apple's Web site, and also through Software Update.
