Mac video editing software isn't as abundant as that designed for PCs. But thanks to some great offerings - mostly from Apple itself - Mac video editing is fun and easy.
iMovie is the free video editing software that comes with all new Apple computers. If you have an older version of iMovie, you'll need to pay to upgrade to iMovie 11. iMovie 11 is an intuitive program that lets new and experienced video editors watch video clips, edit video and audio, and share videos on the web or on DVD.
Adobe Premiere Pro software offers a start-to-finish video production solution for Macs and PCs. Using Adobe Premiere Pro you can work with virtually any video format thanks to native editing support for DV, HDV, RED, Sony XDCAM, XDCAM EX, Panasonic P2, and AVCHD.
