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
