Turbo.264

Turbo.264 is the easiest and fastest way to convert videos to superior quality H.264 (MP4) files for iTunes, and is perfect for anyone who wants to put their own video content on an iPod®, iPhone™, Apple TV™ or Sony PSP®. Because Turbo.264 is a hardware encoder, it frees up the processor for other tasks while video encoding is in progress. Think of it as a "co-processor" for your Mac-a real benefit for anyone who likes to keep several applications open while converting videos, especially on older Macs.
Turbo.264 comes with its own video converter software. The application converts the files, drops them into iTunes, and automatically syncs with an iPod, iPhone, or other device connected to iTunes.
Turbo.264 also supports the export command of most popular Mac video applications, such as iMovie®, QuickTime Pro®, Final Cut Pro® and EyeTV®. Turbo.264 works in conjunction with these applications to dramatically accelerate the video encoding process, and is highly recommended for use with EyeTV's Wi-Fi Access feature.
