Matrox Video VS4Recorder Pro multi-camera recording app is designed for use with Matrox VS4 quad HD capture cards to frame-accurately capture up to four video and audio inputs to create files for use with popular editing apps from Adobe, Apple, and Avid, and for archiving. H.264 is provided in either MOV or MP4 wrappers. AVI files can be created using the high-quality Matrox MPEG 2 I-Frame codec. MOV QuickTime files can be created using DV, DVCPRO, DVCPRO50, and DVCPRO HD. The VS4Control feature allows synchronized, frame-accurate recording of an unlimited number of video sources simply by networking multiple VS4 machines together in a master-slave configuration. On a single network, as many VS4 units as needed can be grouped into any number of master/slave configurations. The master/slave groupings can be easily reassigned in any way at any time. VS4Recorder Pro also functions as a multiviewer, offering pristine video quality even when monitoring interlaced sources on progressive computer monitors. VS4-based systems are also ideal for multi-camera live production streaming with Telestream Wirecast for Windows.
