Using Two IEEE-1394 Cameras 

Use of two digital cameras simultaneously offers many benefits. First, there is no longer a need for an expensive external hardware “video mixer” device—this is done internally using software. Second, the center of each video frame is previewed, as opposed to the left and right sides exclusively, which forced odd camera angles to achieve the desired effect. Finally, two full-frame videos are produced when recording with this mode. 

Note: “Continuous” recording of two cameras is dependent upon the ability of your PC to “keep up” with the demand of writing to two movie files simultaneously—slower PCs, especially slower laptops, may be unable to meet this challenge. 

Due to bandwidth considerations, in order to use two IEEE-1394 cameras, each camera must have its own channel. This means with a desktop configuration, two Firewire interface cards are required, one for each camera, regardless of the number of ports each card has. With a laptop configuration, you may connect one camera to a built-in Firewire port, and the second camera to an interface card inserted into the PC slot. 

If you experience problems with bringing your system up in dual-camera mode, try turning both cameras off. Then, turn your cameras on one at a time, pausing several seconds between cameras.
