background
Use V-Screen to electronically replace the backdrop—typically a blue or greenscreen—with a
digital picture or video clip. Greenscreen effects typically require some adjustments during
setup to achieve the best results.

Manually adjust camera settings for V-Screen
Whether you are using a webcam or a camcorder, turn off its automatic settings and manually
adjust it for V-Screen.
Access the camera properties:
■
On a camcorder, use the buttons or menus on the camera to make adjustments. To
find the location of the automatic gain, white balance, exposure, and iris controls, see
the camera manual. Some camcorders allow you to lock or hold all automatic settings
with one switch.
■
On a webcam:
In Adobe® Visual Communicator® 3, click the Setup tab, and then select Video.
Select Properties to open the camera control panel.
Turn off all auto settings, including white balance, gain, iris, exposure, and focus.
Manually adjust the camera’s gain, saturation, frames per second (fps) or shutter speed
settings for V-Screen, keeping the following tips in mind:
■
If the webcam or camera has gain controls, set them as low as possible while still
having a bright enough picture. If the picture is too dark with gain at a low setting, the
camera might need more light.
