SECTION 4.11 MORE ABOUT M/E
S
Depending on your model, four or eight M/E (Mix/Effect) buttons sit innocuously on
TriCaster's Switcher rows. They may seem like other video inputs, but in reality they
possess very powerful features. An M/E permits a composition to be prepared from
multiple sources as just seen, using keying and other effects. They can be used in
many other ways too – perhaps as an additional 'switcher' to provide a supplemental
video mix, or for more elaborate applications (including virtual sets).
NOTE: In addition to the two sources just considered (Inputs A and B), TriCaster 8000's
M/E's (only) also provide two more primary inputs – C and D – and four integrated Key (or
Overlay) channels, compared to one M/E Key channel on the other models.
4.11.1 COMPOSING M/E LAYERS
When we ended the previous section, the simple 'weather map' setup (Figure 74) we
created was on Program Out. (Remember that LiveMatte is already enabled for the
greenscreen shot from our previous exercise.)
We can use a few of the unique features of M/Es to dress up our production. For
example, we might want to transpose the greenscreen talent shot to one side, placing
it off center in the result.
1. Click the Position button just to the right of the A row label to open the Position
panel for that input.
There are three sets of numeric sliders in the Position group in this panel: one with a
four-pointed arrow button, a Rotation group, and Scale controls identified by a
magnifying glass button.
Experiment with these controls a bit to see how they work.
Hint: Shift + double-click a control to reset it to defaults.
You can drag the mouse over the buttons in each group to freely adjust Position,
Rotation or Scale on multiple axes at once, or use the numeric mini-sliders to adjust
just one property at a time.

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.
