Doing Roll Edits in the Viewer
Final Cut Pro allows you to perform roll edits in the Viewer by setting In or Out points
while the Roll tool is selected.
To do a roll edit in the Viewer:
1 Open a sequence clip in the Viewer.
2 Select the Roll tool in the Tool palette (or press the R key).
3 Do one of the following:
 Drag the In or Out point along the Viewer’s scrubber bar to roll the edit.
 Press I or O to set a new In or Out point.
Look in the Timeline to make sure the roll edit did what you expected.
Tips for Using the Roll Tool
 If you can’t drag any further while rolling an edit, you have reached the end of
the media on one of the two clips. Final Cut Pro displays a Media Limit message
in this case.
 With the Roll tool selected, hold down the Shift key to switch temporarily to the
Ripple tool.
 While dragging, press the Command key to “gear down” and make a more precise edit.
