What is a .FILMCPK file?

FILM_CPK is Sega's multimedia container format, used in Sega CD and Sega Saturn games for full-motion video (FMV). It typically contains Cinepak-compressed video interleaved with uncompressed PCM audio. The format is supported by FFmpeg and GStreamer.

Background

Sega developed the FILM (and FILM_CPK) format for its CD-based consoles. Files with .film_cpk or .filmcpk contain video and audio for in-game cutscenes. The Cinepak codec was commonly used for video compression. FFmpeg's libavformat includes a Sega FILM demuxer, and tools like Sega FILM Tools 3.0.1 allow homebrew developers to create and play Saturn-compatible video. The format is primarily of interest to retro gamers and emulator users.
