The new Blackmagic MultiView 4 HD model is a low cost multi viewer that lets you simultaneously monitor 4 different SDI video sources on a single display. Each view is a completely independent video monitor with overlays that you can turn on and off such as custom labels, audio meters and more. Full frame re-synchronization on each input lets you monitor any combination of video signals, even if they are different frame rates. The multi rate 3G-SDI connections are compatible with all existing SD and HD equipment and formats up to 1080p60, including Level A and B devices. Plus, you get both 3G-SDI and HDMI outputs so you can use traditional SDI displays or even low cost big screen televisions.
