Smacker video is a video file format (with the .SMK file extension) developed by Epic Games Tools, and primarily used for full-motion video in video games. Smacker uses an adaptive 8-bit RGB palette. RAD's format for video at higher color depths is Bink Video. The Smacker format specifies a container format, a video compression format, and an audio compression format. Since its release in 1994, Smacker has been used in over 2300 games. Blizzard used this format for the cinematic videos seen in its games Warcraft II, StarCraft and Diablo I.

The format has been reverse engineered and implemented in libavcodec. A non-commercial SourceForge project libsmacker released an open source decoder in 2013.
