Pixlet

Pixlet is a video codec created by Apple and based on wavelets, designed to enable viewing of full resolution, HD movies in real time at low DV data rates. According to Apple's claims, it allows for a 20-25:1 compression ratio. Similar to DV, it does not use interframe compression, making it suitable for previewing in production and special effects studios. It is designed to be an editing codec. However, this makes it poorly suited for broadcast use, due to high bitrates.
