To explicitly select a region between Timeline In and Out points
1 Turn on the Auto Select controls for tracks you want to select from, and turn off the Auto
Select controls for tracks you want to exclude from your selection.
2 Set In and Out points in the Timeline.
3 Choose Mark > In to Out (or press Option-A).
The region of clips between the In and Out points on tracks with Auto Select turned on
is selected.
In some instances, the Auto Select controls are ignored:
• If no Auto Select controls are turned on : Nothing in the Timeline is automatically
highlighted, and only selected clips will be operated upon (just as in earlier versions
of Final Cut Pro).
• If you use the Selection, Range Selection, or Edit Selection tool to select clips in the
Timeline: These selections are prioritized over the region between sequence In and
Out points on tracks with Auto Select turned on.
• If you use a command that only applies to the topmost visible video clip item (such as
switching or cutting between multiclip angles, or performing match frame operations): The
clip item seen in the Canvas is affected by your command, not the clip on the
lowest-numbered track with Auto Select turned on.
