On old school analog switchers and routers black burst was input 1, it was the timing reference as well as the system black. When manual timing was necessary your input sources would be timed against the black signal which was also the reference.
Gary implied that an SDI signal could serve as a sync source though an Atem was the best way. If the cam can sync to an SDI signal, and not some specific anc data, then there should be no reason why the cam can’t sync to any SDI source.
I use Ross sync/TC generators that can generate just about any reference or SDI signal one would require tho I’m guessing the goal is something Lockit sized.
Good Luck
Thanks, Howard. Yes, we have several 3D rigs, which should all be independ and very true, the goal is something in the form factor of a Lockit. The Ross products seem to be all 19".
Got a message from Gary that there will be no options for trilevel sync for this camera. So I will have to investigate the best and smallest solution for feeding SDI to the cams. Your right, it doesn't have to be black, but it needs to be in sync with the external TC.
Combining a Lynx P TG 3601 with a Lockit would be a valid option and is probably doing, what is needed here. But it's another box on the rig, with more cables and more things which can go wrong. If the SDI of a Lockit or the Ultrasync would deliver a SDI feed, this would be the solution. But unfortunatelly they aren't. I have mailed to Lynx, if I can test their unit.
Thanks again for all your valuable information.
Cheers,
