HEVO 2.0
Following a comprehensive upgrade, HEVO 2.0 technology redefines the experience.
With extended transmission range, lower latency, and support for dual transmitters and one receiver, Cosmo C2 aims to elevate your workflow.
Seamless Frequency Hopping
Powered by self-developed HEVO 2.0 technology, Cosmo C2 automatically detects surrounding frequency interference and seamlessly switches to a clean channel, which ensures uninterrupted transmission and an immersive experience.
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.
FPS Booster
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.
Fractional Frame Rate
Cosmo C2 can transmit HDMI/SDI fractional frame rate input and output, catering to your flexible needs while shooting.
Frozen Frame
When transmission is interrupted, Cosmo C2 freezes the last frame of the video feed, preventing the display of the manufacturer’s logo. You can also customize the logo image as you please with a USB flash drive.
