FIGURE 217
TriCaster's supplies a digital version of this traditional tool. The controls under the
Matte label, as you would expect, allow you to define and adjust the matte for the
corresponding video input.
13.2.1 COLOR
Initially, LiveMatte removes a specific color from the foreground image. This color is
chosen using the Color button.
To choose this key color, click on the Color button (Figure 217) and keep the mouse
button depressed. Drag the eyedropper tool over one of the video monitors to choose
the color you wish to remove and then release it. The neighboring 'color well' is
updated to show the color selected.
13.2.2 TOLERANCE
No physical greenscreen is perfectly comprised of one color. Wrinkles, folds and
shadows along with the seemingly inevitable uneven lighting result in difference. For
this reason, TriCaster provides a numeric slider labeled Tolerance just beneath the
Color picker.
The Tolerance setting allows you to broaden the range considered as the key color,
including more 'near-neighbor' colors to be included in the matte. A low tolerance
removes only color values close to the primary or key color. As you raise the
tolerance, you extend the range of values on either side of the primary color that will
be treated as transparent. This allows you to deal with those imperfections we
mentioned.

Questions and answers
Can the switcher have a background still with PPT slides over top rightside of frame, and then have live camera feed on left?
Yes, the NewTek TriCaster Mini can display a background still with PowerPoint slides on the right side of the frame and a live camera feed on the left. It supports compositing live and video-on-demand inputs, including PowerPoint slides from a connected computer. The system allows for chroma key operations and mixing multiple video sources, enabling such a layout.

my tricaster only has one KEY option and two DSK options and 4 Mix Effect options. is there a way to add more of these items into my tricaster layout?
The TriCaster Mini includes Key layers in M/Es, which function similarly to Downstream Key (DSK) layers but are embedded upstream in the Mix Effect (M/E) output. However, the provided context does not mention the ability to add more KEY, DSK, or Mix Effect options beyond what is already available in the system.

Thank you for answering my question. There is a buzz on the output of our Tricaster410. Not sure why this is happening now.
A possible cause of a buzz or distortion on the output of a NewTek TriCaster Mini could be incorrect audio gain settings in the Output Configuration. Specifically, the gain controls for STREAM 1 and STREAM 2 may need to be adjusted. Setting the gain to -20 can eliminate distortion and align the output level with the TriCaster MASTER.
