The Datavideo DAC-45, 4K Up/Down Cross Converter, is the successor to the popular DAC-70. It has the same features, plus 4K HDMI support and Genlock. The built-in super resolution scaling engine allows you to convert resolutions as low as 720x480 up to UltraHD 4K.
The DAC-45 allows you to convert video signals from VGA, HDMI and SDI inputs (with audio) to 4K HDMI or 3G-SDI output. It also allows instant and automatic switching between 4K, HD and SD formats when the video input changes. The DAC-45 Center Utility software is also provided as a free download from the Datavideo website. This application allows you to designate various video and audio settings, as well as obtain device information.
