- Description
- id RoQ is a proprietary video (and audio) container format developed for use in video games. It uses a custom codec combining vector quantization for video and a simple compression scheme for audio, designed for fast decoding on limited hardware. It was used in several id Software games such as Quake III Arena and Return to Castle Wolfenstein to play full-motion video cutscenes.
- Compressed bitmap image that uses wavelet compression instead of the DCT compression used by standard .JPEG images; supports 16-bit color, alpha transparency, and lossless compression.
