Note: Some TriCaster features do not provide full functionality for some of the alternate
formats. For example, certain of the formats do not support embedded timecode.
Let's consider TriCaster's two MPEG-2 formats first.
TriCaster's 'double-rate' MPEG-2 format for capture is
comprised entirely of 'I-frames', resulting in excellent
image quality. Two variants are provided; the choice
principally affects color sampling applied to captured
clips.
MPEG-2 Compatibility encoding invokes 4:2:0
color sampling (similar to that of the popular 'DV'
and 'HDV' formats).
MPEG-2 High Profile encoding raises color
sampling to 4:2:2. These files retain more color
information than standard DV/HDV files as well as
many other file formats.
fidelity is especially valuable for chromakeying
purposes. (Please see the notes which follow
regarding file compatibility.)
The 4:2:2 sampling and high fidelity of the MPEG-2 High Profile format make it
especially suitable for chromakeying applications.
Support for High Profile MPEG-2 files by various applications is not universal,
however. It would be prudent to test file compatibility with your favorite third-party
programs before making extensive use of this option.
Note: TriCaster's High Profile MPEG-2 files meet the "High Profile" MPEG-2 definition

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.
