Signal Muxing & Stereo3D Monitoring

It will be necessary to view the output of the two cameras superimposed on each other in order to

calibrate. Some professional 3D monitors are capable of accepting separate left and right HD-SDI

signals (genlocked) directly from the HD-SDI out of the cameras. However most 3D monitors,

including consumer HDMI1.4 compliant 3DTVs, will require a "muxed" signal in a standard 3D format

like side by side, top/bottom or frame-packed. There are several third party "muxing boxes" on the

market for about $500USD that can combine the HD-SDI outputs of the two cameras into a single

HD-SDI or HDMI signal for monitoring on a 3DTV.

MOUNTING THE CAMERAS

Proper con guration for CMOS shutters

The CMOS sensors in the XF105 and XF305

camcorders use a rolling shutter that

requires a particular mounting con guration

in a beamsplitter rig. The tops of the frames

must match so there is no rolling shutter

disparity between the sensors. If the mirror

in your rig faces the ground and the upright

camera mounts underneath then the camera

can be mounted on the plate normally. If

your mirror faces up and the upright camera

points down then the camera must be

mounted upside down so that the top-

bottom orientation of the sensors match.

ALIGNING THE CAMERAS

Reset Focal Length Guide

Zoom both lenses all the way in, frame each on a common target, and then navigate to the CAMERA

SETUP -- ZOOM -- FOCAL LENGTH GUIDE menu item and select "SET TO 0" and then press SET. Press

MENU to return to the normal display. Now as you change the zoom you will see a

number displayed on the screen that corresponds to the focal length of the lens. This

allows you to set both lenses to the same focal length. However, this number does

not refer to the actual focal length of the lens in mm and does not guarantee a match.
