- 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.
- Djot is a lightweight plain-text markup language designed as a faster, simpler alternative to Markdown with unambiguous syntax rules. It is used for writing documents that can be converted to formats like HTML, PDF, or others. The .dj extension marks plain text files written in this syntax.
