camera to camera sync?

[Andrae Palmer]

Is it possible to do a camera to camera shutter sync with the Epic? Deanan did mention it a few times on the board (in 3D section) but I'm not sure how it's done.

Epic can sync from camera to camera without external sync.
This is especially useful for offspeed, moco, etc.

However, having a genlock sync input helps phase lock
timecode to frame time while also locking monitor outputs
to genlock (good for SIP, etc).

So you can run without external sync depending on
what your requirements are.

My Scarlets sync pretty well with just the gig-e cable. Let me rephrase that: the start time for each frame is very close to each other, but there will be a couple of frames extra at the head of the shot on one of the cameras. This can be corrected for by sliding the camera in a time line.

I was referring to shutter syncing instead of timecode syncing. But... do have the gig-e cable... how do you configure it for timecode syncing?

I've been curious about this as well, especially after some of Deanan's replies...but the more I've looked into it, it still seems that you need an external device to get tri-level sync from (gen10) especially if there's SDI monitoring involved.
Potentially I think there's a feature in there somewhere that just hasn't been enabled yet...
Was gonna talk to support about this specifically once i got my bodies in...

I'm wondering it it's possible with the RS232 to RS232 cable found here: http://www.red.com/store/cables/prod...to-rs232-cable

In the manual it says this:

CTRL (RS232 CONTROL)
A 4-pin LEMO connector supports RS232 remote control for stereoscopic camera image capture, and third party metadata ingest applications.
The shutter Sync Output signal acts as an immediate response hardware tally of a scan. This is useful for 3D or motion control applications where a slave camera or lighting device needs to be synchronized to a master camera.
Alternatively, this output pin may be used as a GPO (General Purpose Output) tally, whose function is programmed in the USER KEYS menu. Default is Record Tally.

I've got these questions as well as some clarifications in for my Bomb Rep to field, which hopefully will lead to someone in support. Keep ya posted if i get anywhere

[Andrae Palmer]

I've sent a few questions to tech support myself... will update the thread on any responses.

Got an answer from John Restivo at RED that what Deanan posted does not apply to the EPIC. We will will need timecode and gunlock generators... no way around it.

[Les Dittert]

So it does apply to Scarlet ? I tested with gig-e, and it's pretty damned close, after correcting the 1 or 2 frame slip.
Easy test: start the two cams, draw fast circles with a laser pointer on a wall. The laser marks on the frames will tell tale the timing clearly.

I was referring to shutter syncing. How did you export the timecode using the gig-e cable?
