Introducing the RGB guitar solo. Viditar is Livid's pioneering custom made video instrument for real-time video expression and performance. Viditar's integrated hardware and software takes video performance away from the computer and onto the stage. Generate high quality real-time video performances by combining video triggering, scratching, source mixing, and live camera manipulation, to give you total control over hundreds of effects and thousands of media files.
