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.
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.
after some time I got my hands on a Magma Expressbox 3T PCIe external expansion card to run on my macpro dustbin.
After advised that it does output TC via HDMI, I installed a Blackmagic Decklink Mini Monitor 4k (HDMI/SDI) card, installed the Monterey driver (advised by BM tech support).
Whilst video outputs nicely I cannot get Timecode embedded in HDMI via Video Out CHOP.
Have set timeline playback to 50fps, set same in TC Chop. Have referenced the TC Chop in Vid Out Chop. Vid Out Chop set to BM card. Set same fps in BM card control panel at 1080p.
Have set HDMI Timecode to ON in Atomos NNinja, also tried Source TC as HDMI and Free Run.
Nothing seems to work.
Any ideas - I only have the Magma for a few weeks to test.
[EDIT] I installed Davinci Resolve and played back through BM card, timecode is present and triggers Atomos recorder ser to Freerun TC.
I used a Maga 3T PCIe exp device connected to Mac via TB2, I put a BM Mini Monitor 4k, using SDI to a ATOMOS Shogun. After much messing around I am able to trigger REC on ATOMOS.
Unfortunately using HDMI out on same BM card (even though it does deliver timecode to ATOMOS - only when I use Davinci resolve) otherwise it doesnt pass from TD TC through to ATOMOS. This is maybe a BM (or TD) issue which I am communicating with BM about - HDMI needs to put out the same TC format as does SDI (if that’s poss).
