The Evolution of Sega Video Tech: from Pioneer Laserdisc to Saturn Media
By Chloe Bennett
By late 1991, Sega sought to port that cinematic edge into consumer living rooms. The Mega Drive was a technical powerhouse for raster scrolling, but its visual palette was notoriously tight, displaying just 64 colors simultaneously from a 512-color master palette. When the Mega-CD launched in Japan, arriving in North America as the Sega CD in late 1992, it carried a 12.5 MHz Motorola 68000 co-processor, custom graphics scaling chips, and a single-speed CD-ROM drive pushing a meager 150 kilobytes per second.
Pumping video through that narrow pipe required brutal compression compromises. Programmers could not lean on standard MPEG algorithms; dedicated decoders were far too expensive for consumer retail boxes. Software studios had to invent custom retro gaming video codecs on the fly.
Tom Zito’s Digital Pictures spearheaded this shift using proprietary TruVideo compression. Originally conceived for Hasbro's unreleased Control-Vision VHS console, TruVideo chopped footage down to single-digit frame rates, posterized source frames, and used custom dither patterns to fake intermediate shading. The resulting Digital Pictures FMV games, including Night Trap, Sewer Shark, and Double Switch, drew sharp criticism for grainy, postage-stamp video frames surrounded by heavy static interface borders. Yet they sold hundreds of thousands of units. Sega CD full motion video turned interactive software into a mainstream cultural lightning rod, triggering the 1993 congressional hearings on video game violence.
