Stereoscopic Multiplexer Overview
Stereoscopic Multiplexer is a Windows driver that allows you to capture stereoscopic video from two separate cameras. It combines video data from DV camcorders, Firewire or USB webcams and most other capture hardware to a single stream in side-by-side format. It can be used within Stereoscopic Player as well as third party video software that supports WDM capture devices, for example Windows Media Encoder.

Stereoscopic Multiplexer System Requirements
From the technical point of view, there is no need to use two identical capture devices. However, we recommend to do so in order to minimize differences in color, brightness, contrast, focus and zoom between left and right images.
The Stereoscopic Multiplexer does not replace genlocking or other means of hardware synchronization. It searches for left and right frames with minimum time offset, but cannot eliminate the remaining mis-sync. This would require to interpolate frames, which is unacceptable from a quality point of view. For DV-Camcorders featuring a LANC port (Sony, Canon), dual camera remote controls, for example the LANC, are the easiest way to obtain almost perfect synchronization.
Important: When using DV devices, it is necessary to connect them to separate Firewire controllers. Using two jacks on the same controller does not work! If you use Firewire webcams or industrial cameras according to the 1394 Trade Association's Digital Camera Specification, it depends on the resolution and frame rate whether two controllers are necessary or not.

Stereoscopic Multiplexer Frequently Asked Questions (FAQ)
Until HDV capture drivers become available, you can switch your camcorder's output to DV mode to get a stereoscopic preview using Stereoscopic Multiplexer. It is possible to record in HDV even when the Firewire output is set to DV mode.
