RTMP and NDI|HX Streaming

The Cosmo C2 unlocks RTMP streaming for direct live streaming to YouTube, Twitch, and other platforms. The receiver unit supports NDI|HX protocol, transmitting video streams via a single network cable for a cleaner production space.

FPS Booster, Fractional Frame Rate

Using a frame rate compensation algorithm, the Cosmo C2 receiver can convert low frame rate inputs like 1080p24/25/30 to high frame rate outputs at 1080p60, making smoother visuals. The Cosmo C2 can also transmit HDMI/SDI fractional frame rate input/output signals to ensure flexibility while filming.

Versatile Power and Mounting Options

Each unit can be powered via DC input using the included power supply when working on set. In field applications or in studio spaces with limited outlets, both units offer battery plate options. The transmitters feature an L-series battery plate, and the receiver features a V-mount battery plate for higher-capacity power sources. Use the 1/4"-20 threads on the units or the cold shoe adapter to secure them to the mounting configurations of your choice.
