SECTION 9.8
PREVIZ
The Look Ahead Preview viewport above the Switcher shows the
outcome of the currently configured transition before it is performed.
Previz takes this capability further, allowing you to pre-visualize
effects in motion, including T-bar operations.
You can preview any Switcher and M/E effects (including DSK/KEY
layers) without fear of disrupting Switcher (or M/E ) output. Create
complex compositions in this mode and copy them back to the
original M/E (or Switcher) or a different one.
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.
Use the PREVIZ menu to copy the current settings of the source ( Switcher or M/E ) into the dedicated Previz
pane, located with the M/Es, since it can be thought of as a specialized M/E – one never visible on output.
Hint: Use the “M/E Follow” Workspace to monitor your experiments in the Previz pane.
When you arrive at a composition you like, simply select the Paste Previz menu item in the desired
destination ( Switcher or M/E tab) to send it 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 9.9
COMPS AND MEMS
You’ll also 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 disc uss the Comp Bin in full soon (Section 14.8), but at this point we want to distinguish them
from Switcher MEMs. Bumping the cursor at the left edge of the screen adjacent to the Switcher or an M/E
reveals a MEM bin with features that are quite similar. The primary difference between MEMs and Comps is
that the former retain (and apply) all settings in the Switcher including source selection.
SECTION 9.10
UNDO/REDO
The Undo/Redo feature is a very useful innovation that 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.
