Genlock /Sync, Dip Switch Setting Clockit

[cinepost35]

The monitoring of Jamsync presence would be nice. The color idea sounds like a possible solution.

More shooting yesterday and all looks stable. In post I checked the sync of frames and all is sinced up to the single frame on all shots. We had to sync almost pixel to pixel and important thing for such jobs is to go to the shutter menu and set the phase to 0 deg.
Also the World clock output can drive up to 4 inputs. We did drive two, this way we were making sure that phase is identical on both cameras.
It may happen that when doing jamsinc for the first time after you power on both cameras when both cameras are already in genloc the jamsinc will sinc one camera one frame less or more than the other one.

Another words there will be one frame difference on the TC display reading for the same frame content (picture) between these two cameras.
It mean that you jamsinc reading came just at the split of the frame and you flipped to the second frame for one of the cameras.
Once this will happen it will stay like this for the whole day on all clips till you power off the cameras.

In my experience, there's generally three main reasons (other than a total equipment failure) why a device won't accept a TC Jam.

1) Bad or improperly wired jam cable
2) Framerate incompatibility
3) TC output source voltage is too low

So can you feed 29.97 into the camera and still shoot 23.98? Or is that the framerate incompatibility you refer to above. I am shooting a band with Red and recording on a D88 8 track recorder which will only do 29.97/30fps. I thought I would rent 2 Clockit boxes and use the TC from the Audio Recorder to send to the camera.

Any ideas?

Are you saying the camera doesn't genlock at 29.97 16:9 4K?

Yup, that is exactly what you should be doing !
