- 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.
- The JPEG 2000 Code Stream (j2c) file format is a type of image file format that is part of the JPEG 2000 family of image standards. This format is specifically designed for encoding images in a highly efficient manner, allowing for both lossless (exact reproduction) and lossy (approximate) compression. The j2c format focuses on the core coding stream of JPEG 2000 images, representing the encoded image data without additional metadata or structure.
