Uncompressed 4K & HD with Quad 3G-SDI & HDMI Output

pdf datasheet

Uncompressed 4K/HD recorder, the UDR-N50, is designed as a convenient universal deck for studio applications. Quad 3G-SDI plus HDMI output enables 4K-RGB-12bit output for totally uncompressed best video quality. 10G-Base-T with UDR Virtual-File- System contributes fast data transfer for contents screening. Multiple file formats are supported such as DPX, TARGA, TIFF, BMP, CINEON & QT. RS-422 control adds convenient operation directly from edit station.

At shooting scenes, the UDR-N50 becomes a portable but strong recording device. Supporting multiple 4K camera’s Raw-data formats, the contents are recoded into the detachable Solid-State Media –Pack, which comes with a variety of capacities up to 3TB with Raid-5 equivalent redundancy. The detachable architecture helps easy data transfer into your studio facility upon shooting in the field.
