Stereoscopic Multiplexer System Requirements

  • Windows 2000, Windows XP or Windows Server 2003
  • Capture or playback application compatible with WDM drivers (e.g. Stereoscopic Player, Windows Media Encoder)
  • Two cameras or capture cards able to work simultaneously at the same resolution, color space and frame rate

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 ste-fra® 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.

Some cameras require separate controllers even at lowest resolutions.
