ROQ is a legacy video game file format primarily used for storing video sequences in classic video games, particularly in id Software's early game engines. Developed in the 1990s, ROQ files use a custom video compression algorithm that allows for efficient video playback in resource-constrained gaming environments. The format supports low-resolution video with limited color depth, optimized for game cinematics and in-game cutscenes.
Compact file size, efficient video compression, low computational overhead, native support in classic game engines, minimal memory requirements, quick loading times for game video sequences, designed specifically for gaming multimedia needs.
Extremely limited color depth, low video resolution, outdated compression technology, minimal compatibility with modern video systems, restricted to legacy game development environments, no widespread modern support.
ROQ files were predominantly used in video game development, specifically in titles from id Software like Quake and Doom. Common applications include game cinematics, intro sequences, in-game video cutscenes, and pre-rendered video content for older game engines. Primarily found in vintage PC and console game productions from the mid-1990s to early 2000s.
