TrueMotion

From Sega Retro

Truemotion is a audio/video compression format developed by the Duck Corporation. It was used by several Sega Saturn games as an alternative medium-quality format between standard Cinepak that many Saturn games used for FMV, and the use of the VCD card.

Generally speaking, Truemotion is of much higher quality than Cinepak, but inferior to the MPEG compression of the video decoder card. Games that use Truemotion usually feature the "TM" logo both on the packaging and before the game's title screen. Although Duck is an American corporation, numerous Japanese licensees used TM.

There have also been rumors that Truemotion would have been the compression method used by Working Designs to achieve high quality full screen movies without the video decoder card on Lunar SSS, had the US Saturn version actually been produced.
