What is a .FILM file?
The .FILM extension has two meanings: (1) Sega FILM – a multimedia container from Sega for Sega CD and Saturn games, with Cinepak video and PCM audio; (2) Filmkey Player – encrypted video files (originally MP4, MOV, etc.) protected by Filmkey DRM. Filmkey Player is discontinued; Sega FILM can be played with FFmpeg or compatible tools.
Background
Sega FILM was developed by Sega for full-motion video in games like Jurassic Park (Sega CD) and many Saturn titles. It typically uses Cinepak video with uncompressed PCM audio. FFmpeg and GStreamer support this format. Separately, Filmkey Player used .FILM for DRM-encrypted movies; the key was stored on filmkey.ch and the player retrieved it to decrypt. Filmkey Player has been discontinued, so those .FILM files may no longer be playable. When encountering a .FILM file, try FFmpeg or VLC first for Sega-style content.
