General Controls
There are several basic controls in the top-left corner of the filter.
 Numeric button (appears when viewing the visual controls): Click this button to view
the numeric controls for the filter in the Filters tab.
 Visual button (appears when viewing the numeric controls): Click this button to view
the visual controls for the filter in the color correction tab.
 Keyframe controls: A set of three keyframe controls allows you to keyframe all of the
settings in the filter at once. To keyframe individual settings, you need to use the
filter’s numeric controls.
There are two ways to keyframe color correction changes over time. Using a filter’s
visual controls, you can place single keyframes that include the settings of every
parameter of the filter. If you set one keyframe, move the playhead ahead several
seconds, and make further adjustments to the visual controls of the filter,
Final Cut Express automatically interpolates the change from one keyframe’s settings
to another to make the smoothest transition possible.
For more precise control, you can keyframe individual color correction parameters
directly in the Filters tab of the Viewer. For more information about keyframing filters,

 Enable/Disable checkbox: Select or deselect this checkbox to enable or disable the
entire filter. This can be useful if you want to compare your clip before and after the
filter has been applied. When working in the visual controls, you can turn the filter on
and off by pressing Control-1.
