DEFAULT EFFECTS
As mentioned, in Effect mode an M/E may support up to four input layers. The M/E doesn’t transition
between A and B in Effect mode. Instead, effects of various types are applied to the selected video inputs.
Let’s consider the effects in the Default group as examples:
Click the + sign shown when you move the mouse to the effect icon located beside the effect duration.
This opens the
Media Browser . Select the effect group labeled Default under the LiveSet location at left.
With the exception of Advanced Tracking effects, these effects are straightforward compositing effects
involving multiple video layers. Effect output (i.e., the background prior to KEY overlays) is the sum of all
input layers.
If the source assigned to input A is fully opaque, any content in the layers below is hidden. When input A is
at partially transparent, the source assigned to input B is blended into the M/E background layer, and so on.
Hint: Don’t overlook the fact that the input Position controls, including Borders, let you create very elaborate
compositions even with these ‘simple’ compositing effects.
The output of active KEY layers is then added to the effect output before passing the combined result onward
as the final M/E output.
A DVANCED T RACKER
As w e mentioned, effects can be ‘simple’ compositing effects, like most of the Default group, or more
advanced. Before considering NewTek’s virtual set system (a.k.a, LiveSet™), let’s talk about some of the other
effect types. Effects can vary widely in their types, from relatively simple utilities effects to image processing
and advanced compositing effects.

For example, we mentioned that one member of the Default group is unique.
The Advanced Tracking effect takes three video sources (hence is supplied only
with TriCaster models that support 4-layer M/Es) to produce a result that would
otherwise require the use of an additional
M/E .
Set up this effect as follows:
1. Click the label above the Effect icon and use the Media Browser to select the
Advanced Tracking effect from the Default group.
2. Add the clip named Tracking Example.mov (NewTek>Green Screen group) to
the playlist for DDR 1 .
3. Enable Loop mode for DDR 1 .
4. Add the clip named “ Bumper Cars.mov ” (NewT ek>Clips group) to DDR 2 , set it to Loop as well.
5. Add an attractive full frame graphic to the DDR 3 player.
6. Select M/E 1 on the main Switcher’s Program row, to make it easy to view the result of the following
steps.
