Syncing offspeed Cameras w/ Timecode is it possible?

[ronin99]

We are working with a RED Monstro and a BlackMagic PCC, timecode is being jammed to both,.
This is not to sync audio but to sync the two cameras together.

Both have project/base frame rate of 23.976, and our shooting rate is 29.976, to give a slight
gliding/slow mo feel.

When sycning both via timecode in Resolve, the cams have been off everyday so far, sometimes by 6 frames, sometimes 2 seconds and it drifts throughout the day.

I was wondering if we're doing there's anyway to get TC spot on for both or if it's impossible because of the off speed shooting rate, and
therefore it will always be off regardless that both cams have the exact same settings:
23.976 project/base, 29.97 shooting rate

Thanks

So... you're shooting at 29.98? Are you setting your TC sync boxes to 29.98? Or are you using 23.976 and setting your 29.98 as VFR?

Most cameras disable external TC once set off speed, so there's really no way to sync them.

Most cameras cannot roll “free run” timecode when shooting off-speed/over/under-cranking/slow-mo/fast motion(i.e: shooting another frame rate besides the base/project frame rate).

The easiest solution is for you to shoot 29.97 as your base/project/real-time frame rate, sync the cameras at 29.97(DF or NDF, but make sure every device is the same) and handle the slow down in post/drop it into a 23.98 timeline.
