How do I access the Broadcast framerates of your cameras? (1080p59.94, 1080p29.97, etc)

The first thing you need to adjust your rotary dial on the back of your camera accordingly. The new chart for the rotary dial including broadcast framerates is available here. Be sure to reboot your camera after changing this setting. 

Also be aware that none of the 3G-SDI signals work with Black Magic Design Hardware. So 1080p50, 1080p59.94, and 1080p60 do not work into BMD equipment in default.(You can try to use the IR remote control, enter the "SETUP" option through the OSD menu, modify the SDI-3G Mode to LEVEL-B, and then restart the camera for compatibility)
