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, low bitrates make it poorly suited to broadcast use.
