• To slide the clip by a precise number of frames: Type a plus sign (+) or a minus sign (-)
and the number of frames to slide, then press Return.
The timecode entry field
shows the duration of
the slide.
Note: You can specify the default number of frames to trim by changing the MultiFrame
Trim Size setting in the General tab of the User Preferences window. (For more information,
see
“Choosing Settings and Preferences.” )
Slipping Clips in the Timeline
Performing a slip edit does not change a clip’s position or duration in the Timeline, but
instead changes what portion of the clip’s media appears in the Timeline. The Slip tool
allows you to move a clip’s In and Out points simultaneously.
You slip items using
the Slip tool.
Whenever you arrange clips in the Timeline so that edit points line up with musical beats
or other fixed sync points in a sequence, you want to keep your clips in position. These
situations leave you with very little room to adjust your clip because you cannot change
the clip’s duration. You also cannot move the clip elsewhere in the Timeline, because it
would no longer be aligned with the music beats or other sync points in the sequence.
Therefore, all you can do is move both the In and Out points of the clip simultaneously,
keeping the clip’s duration fixed.
