Do you mean time code to do a multi camera edit or are you shooting a stereo 3d and you need trilevel sinc?

Good question. There is no obvious or documented way that I know of.

Maybe BMD could make an improved timecode functionality that would make that possible or maybe easier via USB PTP.

Anyway, that would be a good question to make to BMD technical support, maybe they have some solution.

Only the Ursa Minis take genlock, LTC doesn’t contain enough information to establish shutter sync.

Good Luck

From the avatar of Fabien i suppose about stereo 3d shooting.
To shoot stereo 3d motion you should have a tri level sinc at pixel level, or pan and camera motion cause headache of everyone see it in a theather.
long story short answer, if you shoot stereo for tv, brain not request so big precision, too small difference to have disturb.
if you shoot for theather the big proiection require perfect sinc of both eyes at pixel level or you reiceve a big earthsquare sollecitation, and sensible people like me vomit even the soul.
very few cameras had internal electronics to do that kind of sinc, and today that 3d fever is gone, i think no more producer add it for 3d, but only for live sinc genlock.

i hope so.
i did stereo shooting - post - 3d animation for many years, i would like to see good stereo 3d movies, but i hate every free glasses tv/monitor that i saw, few movment and eyes are exchanged with great headache.

I not have big problem with glasses, i just had glasses, i simply add polarizer lenses over, but only if projection is well setupped.
