aspect lock. To restore the marquee’s standard widescreen aspect, simply drag the
border again without the Ctrl key
depressed.
o The next Video Source option shown in
the menu is Window. This is a
particularly useful option, as it allows
you to ‘snap’ iVGA to a specific
application window (or child window).
For example, you might designate just the video player pane on a web browser
page or in Skype™ as the source; or perhaps you might want to snap to the video
display pane to an application window.
When you select the Window option in the Video Source menu, a new icon is shown
at right (Figure 228). Click the mouse on this icon, and then drag it to the
application window you want to assign as the source. (The marquee updates as you
drag the mouse around the screen from one application window to another. Note
that it automatically disappears from view when the control panel is closed.)
Hint: Many application windows actually comprise a number of child windows
grouped together. When you drag the marquee around in Window mode its borders
snap to the current child window, showing what is currently selected.
o Finally, if you have any webcams or similar video input devices connected to the
system, you’ll see these listed below the Window option in the Video Source menu.
AUDIO SOURCE
This menu allows you to directly select sound from available audio inputs and system audio
devices (the latter may provide useful level and mixing options). iVGA PRO transmits the
selected sound to the Network inputs of TriCaster’s that support this feature. A nearby mute icon
allows you to toggle sound output on/off.
Hint: Select None to mute audio output. (Privacy mode also temporarily engages Mute.)
