What is a DUK file?

A DUK file is a video saved using The Duck Corporation TrueMotion S video codec. It contains a scene played within a PC or Sega Saturn video game. DUK files are quite uncommon, so most popular media players cannot play them.

The Duck Corporation was a New York company that created a series of TrueMotion video codecs. These codecs were used primarily to produce full-motion videos for video games.

DUK files were produced using the TrueMotion S video codec, which is the first codec The Duck Corporation developed. The following games used videos encoded using the TrueMotion S codec (not all of which were DUK files, some were saved as .AVI or .MOV files):

  • Bubble Bobble also featuring Rainbow Islands (DOS)
  • Blazing Dragons (Sega Saturn)
  • Congo: The Movie - The Lost City of Zinj (Sega Saturn)
  • D (DOS)
  • The Horde (Sega Saturn)
  • NHL All-Star Hockey (Sega Saturn)
  • Phantasmagoria: A Puzzle of Flesh (DOS, Windows)
  • Santa Fe Mysteries: The Elk Moon Murder (DOS, Windows)
  • Solar Eclipse (Sega Saturn)
  • Sonic 3D Blast (Sega Saturn)
  • Spycraft: The Great Game (DOS, Windows)
  • Theme Park (Sega Saturn)
  • Virtua Cop 2 (Sega Saturn)
  • Virtua Fighter 2 (Sega Saturn)
  • Zork: Grand Inquisitor (Windows)
  • Zork Nemesis: The Forbidden Lands (Windows)

How do I open a DUK file?

Because DUK files are so uncommon, most popular media players cannot play them. However, you can play DUK files in VLC media player, and you can convert them to a more usable video format using FFmpeg.
