Tiertex Limited SEQ Video File

An SEQ file is a video file used by Flashback: The Quest for Identity, a video game for MS-DOS released in 1992. It is saved in the Tiertex Limited Sequence format and primarily used to store cutscene animations that appear during gameplay.

Since SEQ files are only used by the Flashback video game, you will most likely never encounter them unless you have installed the game from an MS-DOS CD-ROM onto your computer. Flashback was originally developed by Delphine Software for the Amiga gaming platform, then ported to MS-DOS by Tiertex Design Studios Limited and made available via a CD-ROM.

Tiertex Design Studios Limited is a British video game developer founded in 1986. They released games throughout the 1980s, 1990s, and 2000s for various platforms, such as Atari, Commodore 64, Sega Genesis, Game Gear, Game Boy, Super Nintendo, Game Boy Color, and Game Boy Advance. Tiertex Design Studios Limited ceased in 2003.

Since SEQ files are very rare, there are few programs that support it. However, you can convert an SEQ file to a more common video format with FFmpeg , then open the converted file with a media player, such as Microsoft Windows Media Player or VLC media player .
