Both cameras will now be compatible with Canon’s XC Protocol, which better enables them to be used in live productions and allows them to be controlled remotely via Canon’s RC-IP100 remote controller or via 3rd party controllers.
Both cameras can also now limit the 12G-SDI output to 2K/FHD when recording in resolutions at 4K and above. This allows compatibility from the SDI Out port with 3G-SDI devices.
We have also added the ability to use both the Monitor Out & HDMI output simultaneously. This brings the total number of monitor outputs to three, increasing flexibility in production.
