Loading either class of animation effect into a buffer results in a time control being displayed at right in the
buffer label (Figure 11-29).
Hint: Select a Slow, Medium or Fast preset value from the drop-down menu, drag the mouse left or right
over the time to change the current value, or click to enter a number directly using the keyboard.
For auto-run animation effects, a further control is added to the thumbnail icon when you move the cursor
over it. The Rehearse button appears at the top-center (Figure 11-29). Clicking it plays the animation from
its first frame through to the last, and holds that image.
Hint: In addition to providing a way to preview the effect (by displaying it on the Preview monitor, for
example), Rehearse offers a handy way to re-run animated alerts and similar overlays at will. Remember,
too, that the Macros feature provides a great deal of useful functionality in connection with Buffers and
their display.
Still image Buffers have another very valuable ability, discussed next.

SHARING BUFFERS
If you wish, you can share the Frame Buffer folder, which contains any still images used in Buffers, across a
network. Share Media Folders and Buffers are easily enabled or disabled even during a live production using
the File menu at the left-hand end of the Dashboard.
The files which serve individual still image buffers are located in clearly named sub-folders of the Frame
Buffer folder for each session. These folders are arranged as follows:
Sessiondrive:\Sessions\sessionname\Frame Buffer\Buffer (#)
e.g., D:\Sessions\MySession\Frame Buffer\Buffer 3
The top level Frame Buffer folder for the current session is accessible on the network when sharing is
enabled. This allows still image buffers to be updated across a network using suitable graphics application
(such as Photoshop®).
Note: This special share name assignment is dynamic. Network sharing is activated and the current Buffer
path is automatically updated whenever you enter a session with the option enabled. This ensures that
applications on networked systems can remotely access and update buffer graphics for the current
TriCaster session.

WATCH FOLDERS
The Frame Buffer folder is a “watch folder”. When you save an image into the correct location for a given
buffer, the corresponding buffer immediately updates, even if it is currently displayed. This lets you refresh
overlays virtually instantly from any computer on the same network.

Still image Buffers are normally stored using the popular 32 bit PNG (Portable Network Graphics)
format, but other formats are also supported.
