CRI USM Video is a proprietary video container format developed by CRI Middleware for use in video games. It stores compressed audio and video streams, often using CRI's own codecs, and is commonly used for cutscenes and in-game video playback. It is prevalent in many console and PC games developed in Japan.
The M4V file format is a video container format developed by Apple and is very similar to the MP4 format, with the primary difference being the optional Apple Digital Rights Management (DRM) protection. M4V files are commonly used for TV episodes, movies, and music videos in the iTunes Store. These files can be played on Apple devices such as iPhones, iPads, and iPods, as well as on PCs using iTunes or other compatible media players.
