Size Slidebar data in percent. This is a slidebar that provides
an indication (on the left) of the percent of the
total possible size to be captured. A lower

Position Slidebar event within the captured data. This is a
slidebar that provides an indication (on the left)

captured data. The value is expressed as a
percent. A value of 0% indicates that the
trigger event occurs at the beginning of the

that the trigger event occurs at the end of the
resulting captured data. A value of 50%
indicates that the trigger event is in the middle
of the captured data.
Note: The Buffer Position Slidebar is not
applicable when you select Vsync as the
trigger condition.
