Slider Controls

Sliders are used for settings where the value of the parameter is a number chosen from a range of numbers. They are by far the most common control type in Motion, mainly because of their versatility.

Basic Slider

Sliders are used to choose a value from within a fixed range, such as opacity, which must fall between 0 and 100%, or a color fill which must fall between 0 and 1.

Sliders are also used for parameters that have a commonly used range, but can be set to values outside of that range, such as the amount slider in the Gaussian Blur filter, which has a default range of 0 to 64, but can manually be set as high as 600.

To change a slider value
  • Drag the slider to the left to lower 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 Slider

To the right of each slider is a second control, called a value slider. This control displays the parameter’s current numerical value and has arrow buttons on either side.

Some parameters have sliders with effectively infinite ranges, such as scale, which can be set at any value positive or negative (although the indicator can only display 6 or 7 digits).

Value sliders lack the relative positioning feedback that traditional sliders provide, but they can be dragged directly to modify the value.

To modify the value of a parameter using a value slider
Do one of the following:
  • Click the left or right arrows to decrease or increase the value one increment at a time.

  • Option-click the arrows to decrease or increase the value by .01.

  • Double-click the number and type a new value directly in the field.

  • Click directly on the numbers and drag either left and right or up and down to decrease or increase the value.

    Note: When you position the pointer above a value slider, the pointer changes to a four-way arrow. If you begin by dragging up or down, subsequent horizontal movement will be ignored. If you begin by dragging left or right, subsequent vertical movement will be ignored.
