502 18. Modifiers

The Value Bar

The Value Bar is probably the most important piece of the Waveform
Preview area aside from the waveform itself. The Value Bar appears on the
left side of the Waveform Preview, and it displays the number range for
the value you have chosen to modify. These values can change based on
what you are currently creating a modifier for. Consider this example:

You have chosen to modify the Pan X value of a layer. The X, or
horizontal, axis of each slide goes from -50 on the far left, to 50 on
the far right. You have a total range of 100. If you choose to
modify using a function, you will see the value bar display 100 at
the top, and -100 at the bottom. This is the total range the
waveform can work with.

There are some waveforms that can go higher or lower than the maximum
range. When a value is taken outside of a range ProShow can display, it is
“clipped”. We’ll discuss clipping in more detail later. For now, just
remember that the value bar will display the range of whatever value you
are adding a modifier for. It’s helpful to know what the ranges are for each
value.
You can check the range for any value by looking at the slider in the Effects
tab. The far left position of the slider will be the minimum value, and the far
right position will be the maximum. For example, the zoom value can be
9
adjusted anywhere from 0 to 500%.

9 Some values can far exceed their listed capacity, such as Pan, Zoom, Rotate and
other motion effects. Adjustment Effects are all capped at their max value.
