Slider Controls
Sliders are used for parameters that span a range of numeric values. Sliders are by far the most common control type in Motion.
Basic Sliders
Sliders are used to set values in a fixed range. For example, opacity must fall between 0% and 100%. Drag the slider to set a value anywhere within that range.
Although sliders are fixed-range controls, some parameters can be set to values outside of that limited range. For those parameters, a second type of slider control is available: a value slider, which is described in the next section. For example, the Amount slider in the Gaussian Blur filter has a default range of 0 to 64, but can be set as high as 600 using the accompanying value slider.
Drag the slider to the left to decrease values and to the right to increase values.
Option-click to the left or right of the slider to decrease or increase by a value of 1.
Value Sliders
Although basic sliders are fixed-range controls, some parameters can be set to values outside of a limited range. For those parameters, a second type of slider control is often available, known as a value slider. A value slider appears as light gray number, often to the right of a basic slider. For example, the Amount parameter in the Gaussian Blur filter has a basic slider with a default range of 0 to 64; however, you can adjust this parameter up to 600 using the adjacent value slider.
There are two ways to adjust a value slider: by dragging over the number, left or right, to decrease or increase the parameter value; or by double-clicking the number, then entering a new value.
Parameters with effectively infinite ranges, such as Scale, can be set to any positive or negative value. The value slider can display up to 18 digits to accommodate large values.
Drag right or left over the numbers to increase or decrease the value.
To change the value in larger increments, press Shift while dragging. To change the values in smaller increments, press Option while dragging.
Click or double-click the number, then enter a value in the field.
