Normally, a video screen splitter cuts away a portion of each picture in order to make room on the screen or monitor for the corresponding portion of the other picture. For instance, if set for a 50%/50% split display, only 50% of each picture will be visible. Therefore, special attention should be taken in aiming the cameras at their subjects.
The Model 613 Series provides a unique "anamorphic" mode that squeezes two full pictures to fit, in their entirety, side-by-side, on your display in a 50%/50% split. This optional squeezing causes subjects to look "tall and skinny".
