GENLOCK SYNC:

Genlock is very important in S3D production because it allows the shutters to sync to each other to

prevent temporal disparity and it also syncs the output video signals together so that stereoscopic

muxer boxes can combine the signals.

If you are shooting in 25p, 50i, 30p, 60p or 60i modes then you can easily sync from one camera to

the other by using the included component cable and an RCA to BNC adapter. Both the left and right

cameras must be in the exact same recording mode. Just plug the component cable into the

component terminal of the "master" camera and attach the luminance (green) end to the RCA to BNC

adapter and then connect to the GENLOCK BNC input on the "slave" camera. The slave camera should

stabilize its synchronization after about 10 seconds. You may see a disturbance on the screen while

the synchronization is being locked. If you are using

XF105 cameras you will need to go into the "Other

Functions" menu and then "Genlock/TC Term" menu to set

the input to GENLOCK input signal.

If you intend to shoot 24P then signals from a tri-level sync

generator (like AJA's Gen-10) will need to be input into the

GENLOCK port on both cameras. This is required so that

the pulldown patterns on the two cameras sync perfectly.

With either method you should ensure that the horizontal

and vertical phase in the genlock menu of the slave

camera is set to 0. There should be no need to adjust the

phase.

It is easiest to set your desired gamma, matrix, and other internal settings on one camera and then

save the scene le to a SD card and load on the other camera. This will ensure that both cameras

have the same basic settings. You can save your settings to the SD card by selecting the OTHER

FUNCTIONS menus, TRANSFER MENU and then SAVE TO. Select OK and press SET. Then move the SD

card to the other camera and select OTHER FUNCTIONS, TRANSFER MENU and LOAD FROM. Select

OK and press SET.
