Video Format Converter with 4K Up-, Down-, and Cross-Conversion

The FLOW 2 by Science Image is a versatile video format converter for a wide range of applications in broadcasting and audiovisual signal distribution. With its array of interfaces, compact size, and rugged enclosure, the FLOW 2 can fit easily into any workflow that requires a combination of SDI, HDMI, and Audio signals. This flexible device can capture or output most video formats up to 4K at 60fps and 4:4:4 color sampling over the HDMI2.o and 12G-SDI connections. It also features a high-bandwidth fiber SFP+ connector that is compatible with the Science Image T1 12G-SDI fiber transceiver. With the T1 transceiver installed, the FLOW 2 can send and receive SDI or HDMI signals up to 20KM over standard single-mode fiber. In addition to the video signal, the FLOW 2 can also embed and de-embed stereo audio and function as an intercom system with a headset and microphone connected.
