We’ve considered TriCaster’s Default and Utility effects.  Let’s move on to a more glamorous species, the virtual set, presented in TriCaster as LiveSet™ effects.

LiveSet is one of TriCaster’s most powerful tools, and can dramatically enhance a production.  

With it you can achieve the look of a large, sophisticated studio setting (Figure 169) within a very small studio space (Figure 168), all without the need for external equipment.

Broadly speaking, setup of a LiveSet effect is much like the Default effects previously considered (see Default Effects, Section 14.2.2).  A typical LiveSet consists of a greenscreen shot (usually input A) with LiveMatte applied composited into a virtual set. LiveSet adds the foreground and background for the scene, and additional video inputs may add to the effect in various ways.

Hint: Most virtual sets require LiveMatte settings to be applied to Input A.  Other inputs may also require keying, depending on the design of the virtual set.

To select a LiveSet, click the label above the effect icon in the M/E to open the Media Browser (Section 11.2.2).

The Location List of the Media Browser lists any installed LiveSet groups under the heading “LiveSets”.  Select an entry beneath to show thumbnail icons in the Browser’s File Pane (Figure 170 shows the content of the NewTek location under the LiveSets heading).

Input Position


We discussed Positioning controls for M/E video inputs previously (Section Section 14.4).  It’s worth adding here that Position options do affect the scale, rotation and position for LiveSet video inputs.  You can often use Positioning controls to achieve a ‘good fit’ and natural appearance of talent or another source appearing in your virtual sets (greatly reducing the need to fuss with physical camera positions).

Hint: The Align group of LiveSet effects is provided especially to make it easier for you to adjust cameras and position talent on your physical set to suit the design of typical virtual sets supplied with TriCaster.

Holographic LiveSets

A special variant of TriCaster’s LiveSets are referred to as ‘holographic’.  These effects can be amazingly lifelike and convincing, and are relatively easy to create.

Holographic LiveSet effects are loaded into an M/E in the same manner as any other effect.   Simply move the cursor over the effect icon and click the + sign (Add Media button) that appears to open TriCaster’s Media Browser, then choose the effect you wish to load (several examples are included with your system). Adjust the current view for holographic LiveSets in similar fashion to standard effects using the T-Bar (Zoom) and associated Positioner controls.  The Comp Bin, discussed shortly, allows you to store and apply your favorite compositions.

Preset adjustments made using the mouse vary slightly for holographic effects.  For a standard LiveSet effect, dragging the mouse left, right, up or down changes the camera position in the frame. The right-mouse button zooms in or out.  In a holographic LiveSet, right-mouse operations are the same.  However dragging the mouse on the canvas modifies camera rotation, rather than position.

Hint:  New holographic effects, like standard LiveSets, can be created using the optional Virtual Set Editor application.  A demo version of this utility is installed on your TriCaster, and its instruction manual can be located in Startup>Help.
