Use onscreen controls
Onscreen controls overview
Many eects, transitions, and other items use onscreen controls, superimposed
over the video in the Viewer, to make it easier to adjust a variety of parameters.
In many cases, these onscreen controls duplicate controls in the inspectors,
although in some cases the controls are unique and provide the only way to adjust
a particular parameter.
The controls can be as simple as dening the center of a sheye eect or dening the
more complex diameter, width, and position of a vignette eect.
This section focuses on the types of onscreen controls found in clip eects and
transitions. Onscreen controls are also available in other areas of Final Cut Pro,
including the following:
 Built-in eects: Onscreen controls are used extensively for all built-in eects. See
“Built-in eects overview” on page 236.
 Chroma keying: You use specialized onscreen controls when conguring a chroma
keyer. See “Use chroma keys” on page 383.
 Color corrections: Color corrections can contain onscreen controls used for creating
color masks and shape masks. See “Manual color correction overview” on page 414.
Show or hide onscreen controls
Most of the time, the onscreen controls for transitions and clip eects only appear
when you want to use them and do not appear at any other time. However, there are
times when you might need to show or hide them.
Note: Onscreen controls are always hidden when you play clips in the Timeline.

Do one of the following:
m To show the transition’s onscreen controls: Select the transition in the Timeline.
m To hide the transition’s onscreen controls: Deselect the transition in the Timeline.
