User Manual

To trim while looping:
1 Move the playhead near the edit point you want to trim, and press V to select it.
2 Press the U to choose which side of the edit you want to select in order to ripple or roll
it, and/or Option-U to choose whether you want to trim video+audio, the video only, or
the audio only.
3 Press Command-Forward Slash (/) to enable looped playback.
4 Press Forward Slash (/) to play around the current selection. With looping on, playback
will continue until you stop it. Pre-roll and post-roll can be changed in the Edit panel of
the User Preferences.
5 During looped playback, press the Comma (,) and Period (.) keys to trim the selection
back or forward by a single frame, or Shift-Comma and Shift-Period to trim the selection
in 5-frame increments. If you do this during the post-roll of looped playback, the loop
immediately replays from the beginning so you waste no time seeing the result.
6 When you’re finished, press the Spacebar or K key to stop playback.
TIP: When holding down the Shift key while nudging to do a “fast nudge,” the duration
of the nudge is customizable in the Editing panel of the User Preferences. By default
it’s five frames, but you can set it to whatever you want.
Dynamic JKL Trimming
One of DaVinci Resolve’s most interactive trimming features is the ability to dynamically resize,
ripple, roll, slip, slide, or move selected edit points and clips using the JKL transport control
keyboard shortcuts. This means that you can make an appropriate selection in the Timeline
(edit points to resize, ripple, or roll, or clips to slip or slide) then trim them during playback, while
monitoring audio and watching the video.
Trimming while viewing the selected clip or edit point playing back has the advantage of letting
you get emotionally involved in what you’re watching, as well as experiencing the timing of a
clip as it plays, in order to help you get a better feel for how, exactly, you need to trim a
particular cut.
While you’re dynamically trimming, you see the same two-up or four-up display, the same
Timeline overlays, and the same dynamically updating Timeline that appear when you use the
Trim tool with the mouse. The only difference is that you’re trimming while your program plays.
There are two methods of doing dynamic trimming:
 Quick Trim: You can select one or more edit points or clips, and immediately trim it
by pressing Command-J or Command-L to trim back or trim forward. This is a fast way
of dynamically trimming, but you can only trim forward and backward at 100 percent
speed or greater.
 Turning on Dynamic mode: If you want to do more detailed work, you can press the W
key to enable Dynamic mode (or choose Trim > Dynamic Trim Mode), at which point you
are in a special mode where the JKL shortcuts only trim the current selection, whatever
it happens to be. However, this mode also gives you additional options for controlling
which part of the selection, in the case of multiple selection trims, you want to monitor
for audio/video playback.
