Shot Editor Cropping
The cropping control enables you to cut off unwanted portions of an image. To open
the cropping control window, click the cropping control button. There are four sliders
and four text boxes used to control cropping. Select an image, then slide the slider until
the selected side of the image is cropped as needed. Notice that as the slider is moved,
the value in the text box changes. This value is the number of pixels that have been
cropped. You can also enter values directly.
Shot Editor Chroma Key
Wirecast enables you to perform real-time Chroma Key operations on your sources
during a broadcast. Chroma keying enables you to select a color and replace all
occurrences of that color in an image with some other image. Click the Chroma Key
button to open the Chroma Key controls. Click the Use Chroma Key checkbox to enable
the controls. Use the sliders to set the Key Threshold, Black Clip, and White Clip. Click
the Defaults button to restore all controls to their default state.
Working Top Down
The key color is the color of the background you want to drop out of the resulting
media. The Chroma Key configuration panel is designed to work through the
configuration as a process, from top to bottom, fine tuning your key as you go. It is
important to not over-adjust any one control. A good key color is obtained by finding
the right balance in the controls.
