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.
