Hint: Live Story documents are evaluated on loading. When Live Story determines its evaluation of a specific
command in a Comment could be incorrect, it posts a message to TriCaster
’s Notificat ion panel to note the
ambiguity, in addition to marking the commented text in red in the script pane.
Additionally, a single Comment command can do things that would otherwise require multiple commands
entered on separate lines in a macro. Consider for example, when Live Story encounters the simple Comment
entry “fade tom slow”, it results in the following steps:
1. Select an input named “Tom” (or “tom”, or with a similar string, such as “Tommy” in the input
Comment box) on the Switcher’s
Preview row.
2. Set the Switcher’s Background transition effect to Fade
3. Set the effect speed to Slow
4. Perform an Auto.
To do something similar using a macro, you’d need to enter four separate lines, getting the syntax correct for
each macro shortcut – and since macro commands require an input index parameter rather than a name,
you’d need to know in advance which camera would be pointed a t Tom. If Tom was moved to a different
chair on your set at the last minute, the macro would need to be modified. Using Live Story Creator, you
could simply rename the camera.
Better yet, continuing with the example above, if – rather than naming an inpu t “Tom”, you prepared a PTZ
preset (or Pan and Scan preset, for a non- PTZ source) and named it “Tom”, TriCaster would automatically
select that preset at step 1 above.
Hint: Imagine what this means if you are using a few PTZ cameras to cover a city council meeting, with PTZ
presets prepared for different participants. If two people change seats at the last minute, all you need to do
is update the PTZ presets and Live Story Creator will take care of everything else for you!
So, not only are Live Story Comment commands easier to write, often performing multiple operations with a
single entry, but they are ‘smarter’, and easier to maintain and update. Which brings us to another key
feature.

As clever as Live Story is, at times you will want to experiment, or need to tweak your wording to bring about
the result you intend. As we mentioned, you don’t even need to press Play to test modifications, you can
simply reload the .docx file and hover the mouse over commented text to see the way the embedded
commands have been evaluated.
