National Software Laboratory has debuted Arraysync, a program that syncs QuickTime playback either across multiple displays attached to one computer (PC or Mac) or across a local area network without specialized hardware. It freely mixes Mac or PCs to build video walls or multi-screen video presentations. Mac users have the option of spanning videos without pre-processing; Windows users can use a complementary program called ArrayShaker (also available for Mac) to break up large media files into smaller, more manageable pieces but kept in sync using ArraySync.
