User Manual

The following sections describe each of the special-case multi-selection trim operations that
are possible, along with each one’s special rules and limitations.
Resizing and Rolling Multiple Edit Points
You can resize or roll multiple edit selections at once. In this way, you can adjust the edit points
of multiple superimposed clips all together. Trimming multiple edit points essentially lets you
“gang” them so that all selected edits move together as one.
 To resize multiple clips at once, select the left (outgoing) or right (incoming) half of each
edit point you need to adjust, then use the Selection tool to drag those edit points to
resize them all.
 To roll multiple clips at once, select every edit point you need to adjust right at the
center, so that both the incoming and outgoing halves of each edit point are selected,
then use either the Selection or Trim tools to drag those edit points to roll them all.
NOTE: You cannot combine ripple and roll operations at the same time.
Rippling Multiple Edit Points
It’s also possible to select multiple incoming or outgoing edit points on either superimposed
video tracks, or on the same video track, in order to ripple them all at once. A good example of
when you’d want to ripple multiple clips on the same track is if you’ve got an end credit
sequence of 14 text generators, and you’d like to shorten the entire sequence by a particular
amount. This example can be seen below.
When you ripple trim multiple edits on the same track, how many frames are trimmed in a
particular trim depends on what method you use to do your trimming.
 If you use use the Trim tool via dragging in the Timeline, then you can choose to
ripple the entire selection of edits by an arbitrary duration, for example, shortening
or lengthening the entire selection by eight frames. To do this, DaVinci Resolve
performs your multi-selection trim operation one edit at a time, removing a frame at a
time from each selected edit from the left to the right as you trim, until either you stop
the operation, or every single selected edit has had a frame removed, at which point
DaVinci Resolve begins trimming the second frame from each selected edit from the
left to the right, and then the third, and so on, until you stop trimming. Working this way,
you can use the mouse to trim any number of clips to fit into any duration.
 You can also choose to ripple each selected edit by the same amount, for example
removing three frames from each of the selected edits, all at once. To do so, hold the
Command key down while dragging selected edits with the Trim tool, or use Dynamic
JKL trimming, or trim by entering relative timecode values, or use the nudge keys
(Period and Comma).
To ripple trim multiple edits on the same track:
1 Click the Trim tool, and drag a bounding box in the Timeline to select all 14 edits.
2 Press the U key to select the incoming half of each selected edit.
3 Use whichever trimming method you prefer to ripple the sequence to be shorter or
longer. Dragging using the Trim tool lets you trim by an arbitrary number of frames,
while holding the Command key down while dragging with the Trim tool, using
timecode entry to trim, using the Comma and Period nudge keys, or using Dynamic JKL
trimming lets you trim every selected edit by the same number of frames.
