Apple Motion 2 - Manual (Page 296)

296 Chapter 4 Using the Timeline
To trim multiple objects at the same time:
1 Select the objects you want to trim.
2 Place the playhead at the In or Out position you want.
3 Choose Mark > Mark In (or press I) or Mark > Mark Out (or press O) to set a new In or
Out point.
All selected objects are trimmed to the new point.
Note: If one of the objects doesn’t have enough media to complete the trim, it moves
as far as it can toward the desired point.
Slipping Objects
Slip an object when you want to use a different section of your clip, but you don’t want
to change the object’s duration or where it appears in the Timeline. Slipping is only
possible after you have trimmed a clip.
For example, if you had a shot of a door opening that was 3 seconds long and you
trimmed it down to only 1 second, you could use the Slip function to select which one
second to use: the first second as the door leaves the jamb, the next second where it
is flying open, or the last second where it bangs against the wall.
Note: You can only slip an object as far as the existing unused frames in the source
media.
To slip an object:
1 Press Option so the pointer turns into the Slip pointer.
2 Drag the middle part of the object’s bar left or right.
Dragging to the right replaces the frames with a section from later in the source
material, while dragging to the left uses frames from earlier in the clip.
