100 Digitally replacing the background
■
For optimal results, the saturation should be similar to the digital background you are
using. If you have a brightly colored background, set saturation higher; for a muted
background, lower the saturation.
■
If possible, adjust the camera’s frame rate to 30 or 15 fps.
■
If the camera has a shutter speed or exposure adjustment, set it to 1/50 of a second to
start.
Click OK.

About backgrounds
You can use any image as a background. Visual Communicator includes a set of background
images in the V-Screen Extras and Animated Backgrounds folders in the Graphics library.
Also, check out the Virtual Sets folder in the Video Effects library. You can also adjust the
color of the background or use different backgrounds in the same show.
The icon in the upper-left corner of the V-Screen tab shows the image assigned as the V-
Screen background.
Because animated backgrounds use more processing power than still backgrounds and
increase the size of the video file, consider using still backgrounds.
