MOVIE magic bytes (.movie)
.movie file signature: 4D 4F 56 49 00 | video/x-sgi-movie
Category: Video
The MOVIE format is a legacy video file format developed by Silicon Graphics, Inc. (SGI) for use with its graphics and multimedia systems. It is primarily used to store short animation clips, screen recordings, and other video content in older SGI workflows and applications. As an older format, it is now largely obsolete, though files are generally low risk when handled by standard media software.
