You might use Previz to test your currently delegated transitions and sources before
applying them. Alternatively, though, you can experiment to your heart’s content.
Freely change layer sources, modify Positioner settings, transitions or effects, layer
delegates, test the result of Take/Auto, use T-Bar or Zoom controls with impunity.
Clicking Previz copies the settings of the source (Switcher or M/E) into the dedicated
Previz pane, which really can be thought of as a specialized M/E – but one never
visible on output.
Hint: The best way to monitor your experiments in the Previz pane is probably to use
the “M/E Follow” Workspace.
If, while experimenting, you arrive at a composition you like, simply click the Paste Previz (clipboard) gadget
located beside the PREVIZ button in the desired destination to send the current composition to the target.
Hint: This allows you to very easily transfer all of the settings for an M/E – say, the left camera angle for a
virtual set complete with carefully positioned M/E and KEY layers – to one or more additional M/Es. Then
you can simply swap the effect for the new M/Es to add different angles that match the original perfectly.
SECTION 9.6
UNDO/REDO
The Undo/Redo feature is unique to TriCaster Advanced Edition. This very
useful innovation stores multiple undo/redo states. You can easily revert to
a prior Switcher state, providing another important ‘failsafe’ feature.
Accidents happen. Undo is great for those times when you’ve inadvertently
changed something with unwanted results, but lack time to figure out what
went wrong. TriCaster stores a fresh Undo state whenever the Program row
selection is changed. If you encounter problems and don’t have time to think about what may have gone
wrong, a click (or keyboard Ctrl + z) can quickly get you back to the prior state.
SECTION 9.7
SWITCHER MEMORY
The nearby Switcher Memory gauge (beside Undo) tracks how much system memory is consumed by
currently selected virtual sets, transitions and effects. (If you do inadvertently overtax the effects system by
pre-selecting many, many large custom effects – an unlikely scenario – you might just reach the limit, which
could in turn result in dropped frames.)
SECTION 9.8
COMPS AND MEMS
You’ll notice a button labeled COMP immediately above the T-Bar. Clicking it opens the Comp Bin, which
provides powerful layer and effect control features. We’re going to discuss the Comp Bin in full soon (Section
14.8), but at this point we do want to take the opportunity to distinguish them from Switcher MEMs. Bumping
the cursor at the left edge of the screen reveals a fully functional MEM bin with features that are quite similar
those provided for Comps in both the main Switcher and M/E banks. The primary difference between MEMs
and Comps is that the former retain (and apply) all settings in the Switcher, including source selections.
