What is a .amc file?
File extension details and usage information
An AMC (Acclaim Motion Capture) file is a specialized data file format used to store 3D motion capture animation data. Originally developed by Acclaim Entertainment, this format is standard in the video game and 3D animation industries. An AMC file does not work in isolation; it is designed to be paired with an ASF (Acclaim Skeleton File) file. The ASF file defines the skeleton's hierarchical structure, bone lengths, and degrees of freedom, while the AMC file contains the actual frame-by-frame motion data, specifying the rotation and translation of those bones over time. Because AMC files are typically saved in a plain-text ASCII format, they are highly readable and easily editable by developers and animators. This format allows for the seamless transfer of realistic human or actor movements captured in a studio onto digital 3D character models in various animation software suites.
