Blackmagic Design has released its latest Camera 3.4 firmware for the original Blackmagic Production Camera 4K.

Available free to Blackmagic Production Camera 4K owners, the new update adds support for SDI start/stop record trigger which allows external video recorders, such as Blackmagic Video Assist, to start and stop recording in tandem with the camera automatically.  It also adds SDI RP-188 timecode output support  that enables users to record files with identical timecodes on both their camera and an external recorder.  This makes it possible to use the ProRes or DNxHD files for editing, and automatically re-link the camera original wide dynamic range RAW files with matching timecode for grading and finishing.

The Camera 3.4 update is available now from the Blackmagic Design website at
