Pixlet

Pixlet is a video codec created by Apple Computer to enable viewing of full resolution, high definition movies in real time at low DV data rates. It is a highly compressed codec not meant for broadcast or final production output. According to Apple's claims, it allows for a 20-25:1 compression ratio. It is most useful for production and special effects studios which need to quickly review and transfer HD movie clips across workstations.

When it was introduced by Steve Jobs att Worldwide Developers Conference 2003, it was said that the codec was developed in cooperation with the animation company Pixar.

A Power Macintosh with at least a 1 GHz PowerPC G4 processor is required for real time playback.

Pixlet, while part of the cross-platform QuickTime, is only available on Macs running Mac OS X 10.3 or later.
