Second, the distance from your talent to the screen behind can make a profound
difference in key quality. When the subject stands too close to the key colored
background, the key color reflects back onto the subject, creating a green or blue
fringe that is difficult to remove. If you have available space, move your subject
farther away from the wall.
When good distance is out of the question, you can improve things somewhat by
placing lights above and behind the talent, lighting them from behind with a
complimentary color filter over the light to 'cancel out' unwanted reflection (for green
use a magenta filter; for blue, orange or amber.
Don't overdo back (or top) lighting, however. The limited dynamic range of the
camera means there will be little useful color data in badly over-exposed highlights.
This can make it next to impossible to separate fringe zones (such as hair detail) from
the background (especially when this is also overexposed).
As mentioned above, washed-out areas in the video signal lack sufficient color
information to provide good separation. For similar reasons, it's worth considering
the color characteristics different types of video signals.
SDI connections are ideal, if you can use them. Otherwise, in the analog video
realm you will encounter three main types of camera connections. We
present them here in ascending order according to the quality of video signal
they provide (and as things go, in the reverse order of their cost, and the
likelihood that you will have access to them):
Composite – a two conductor design using the classic RCA connector (also
referred to as a phono connector or CINCH/AV connector)
Y/C – typically using a round, 4-pin mini-DIN connector or two BNC
connectors, Y/C keeps Y (luminance) and C (chrominance) signals separate.
Hint: Y/C is occasionally called "component" (which while technically correct, can
be a bit confusing given the name of the next class), S-Video (legitimate) or "S-
VHS" (completely incorrect, though a common error.)

Do you have a question about the TriCaster Mini and is the answer not in the manual?
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.
