Sliders By default, sliders only show whole integer values. To adjust the corresponding value to within two decimal places of precision: m Hold down the Shift key while dragging a slider. To gear down a slider, allowing you to make more precise changes to the parameter: m Hold down the Command key while dragging a slider. Logarithmic sliders As you move the handle on a logarithmic slider, the rate of change increases faster in one part of the slider than in other parts. The tic marks for logarithmic sliders are unevenly spaced; where they're closer together, the change in the parameter's value occurs more slowly. Final Cut Express HD uses two types of logarithmic sliders: Â Logarithmic slider: This slider has tic marks closer together only on one end, indicating that the rate of change increases faster at the other end. Â Double-sided logarithmic slider: This type of slider has tic marks closer together in the center, indicating that the rate of change increases faster at the center and more slowly at the ends. Logarithmic sliders are useful for parameters that have a huge range of possible values, with a particular range at the top or at the bottom being more useful than the others. Point control Point controls are used to specify locations in the Canvas. To define a new location with x and y coordinates: 1 In the Filters tab of the Viewer, click the point control.
