experience.
Streamlined
Live Streaming
Cosmo C2 supports UVC streaming[2] as well. With a USB-C to USB-C or USB-C to USB-A
cable[3],
you can directly connect the receiver to any computer without the need for capture cards, simplifying the
real-time transmission of on-site video.
Cosmo C2 enables RTMP streaming, a streaming method widely used for its low latency and compatibility with a
wide range of live streaming platforms, such as YouTube and Twitch.
Improve Your Workflow
NDI Protocol Support
The receiver of Cosmo C2 supports Network Device Interface (NDI) protocol, allowing video streams to be
transmitted over a single network cable. This eliminates the complexity and clutter of connections and
creates a cleaner production space.
Smoother
FPS Booster[4]
Through brand-new frame rate compensation algorithm, the RX can convert low frame rate inputs such as 24/25/30P
to a high frame rate output at 60P, making the visuals smoother.
