MOTU, while best known for its audio hardware and software for pro audio, also makes video hardware -- and extended its product line at CES by introducing the HDX-SDI with Thunderbolt, a one rack-space sized pro video interface that enables Thunderbolt-equipped Macs or Windows PCs to capture even uncompressed HD video and features plenty of input and output for video and audio channels. The product is MOTU's first with Thunderbolt technology.
