Trigger start/stop record on Atomos Ninja using Timecode

Hi, I am trying to start/stop record a Atomos Ninja recorder. Essentially the same way in which one would trigger Ninja to record via a camera timecode whilst Ninja is in free timecode running mode.

With TD using VIDEO OUT, one can embed timecode, taken from TIMCODE CHOP. I was able to drop a VIDEO OUT with TIMECODE assigned to it into a WINDOW COMP, so VIDEO OUT still passes vision through even though it shows 'no hardware detected X) into WINDOW COMP.

Though I am only currently using the WINDOW COMP (or Perform) to display TD output on Ninja recorder (i.e. as a 2nd display) using HDMI, but can’t seem to get timecode to embed into video signal.

Any advice appreciated, cheers

Hey! Did you find a work around for embedding the timecode in the hdmi signal?

The timecode assigned to a Video Device Out TOP will only output through the device the Video Device Out TOP is driving. It will not pass through to a Window COMP, as I don’t know of any way to send timecode out of the GPU’s HDMI outputs.

With help of tech support at Blackmagic they informed me these cards output TC over HDMI:

DeckLink Quad HDMI Recorder
UltraStudio 4K Extreme 3
DeckLink Mini Monitor / Recorder 4K
UltraStudio Recorder 3G
DeckLink Mini Recorder HD
DeckLink 4K Extreme 12G
DeckLink 8K Pro G2

I have also purchased a LANCdirector interface to trigger atomos, ating for it to arrive. If you communicate with James he will share schematic to send it 0-5v from a PC to trigger record via computer as well.
