Purpose built software designed by experienced video assist operators allows speedy shortcuts of complex setups and operation. Two real time layers and perfect image sync between them. All effects can be applied independently on both streams. One stream can record as the other plays back. Separate video outputs. Both can be switched between live action, playback or effects previsualization at any time. The software creates a database including the technical features of the shots (focal length, focus, f stop, camera speed, filters...) as well as of the comments. ->
