CPK file extension - Sega FILM/CPK file format

What is cpk file? How to open cpk files?

File type specification:

Digital video and movie file type icon Digital video and movie file type

The cpk file extension is associated with FILM, a multimedia container file format developed by Sega for use on its early CD-ROM home video game consoles. Based on analysis of a number of Sega CD and Saturn games, it appears that the format was first developed sometime during the era of the Sega CD, the first CD-based video game console. There are many early variations of the FILM format observed on a number of Sega CD titles. Further, early FILM files have been observed on at least one 3DO game (Lemmings).

The Sega Saturn video game console, released in 1995, was also CD-ROM-based and apparently offered developers a standardized SDK for full motion video (FMV) playback using a modified variant of the well-known Cinepak video codec.

It is possible to store both audio and video in a FILM file. Alternatively, the format is able to handle either video without audio, or vice versa.
