Working with In and Out points
Setting a clip’s In and Out points is a process called marking. You define the first frame you want to include in a sequence by marking that frame
as the clip’s In point. Then you define the last frame you want to include by marking it as the Out point. In a typical workflow, you mark In and Out
points for a clip in the Source Monitor.
Adjusting a clip's In and Out points after it is already edited into a sequence is called trimming. Typically, you trim clips to adjust how they play
back in a sequence. For example, as you view the edit, you decide that you want to cut to the incoming clip a little sooner than you originally
planned while marking clips. To fix that problem, trim the clip using trimming tools in Premiere Pro.
You can trim clips by dragging the edge of a clip. A clip's "edge" is a clip’s In or Out point, or edit point. Several specialized tools and techniques
allow you to trim an edit point. These tools and techniques allow you to trim more easily and accurately, reducing the number of steps involved and
maintaining the integrity of the sequence.
You can fine-tune trim edits in a sequence in the Trim Monitor. The Trim Monitor’s layout is similar to the Source and Program Monitors, but the
Trim Monitor controls are optimized for precisely adjusting a cut point between clips in a sequence.
You can trim clips in the Speech Analysis pane of the Metadata panel, setting In points and Out points on selected spoken words.
There are many keyboard shortcuts available for the job of trimming, however, a number of them aren't set by default. Go to Edit > Keyboard
Shortcuts (Windows) or Premiere Pro > Keyboard Shortcuts (Mac OS) to set trimming shortcuts.
Online resources for basic trimming in Premiere Pro
Franklin McMahon shows Ripple Edit, Rolling Edit, Slip, and Slide tools in this video from the Layers Magazine website.
This excerpt from the “Adobe Premiere Pro CS5 Classroom in a Book” introduces the more advanced editing tools, including tools for rolling,
ripple, slip, slide, lift, and extract edits.
For more information about trimming clips, see this excerpt from An Editor's Guide to Premiere Pro by Richard Harrington, Robbie Carman,
and Jeff Greenberg.
Working with audio clips in the Source Monitor
Scrub the audio waveform in the Source Monitor
In the Source Monitor, drag to the left or right anywhere on the waveform.
The playhead appears where you click and the audio clip is played, forward or backward, at the speed at which you drag across, or scrub,
the clip.
Zoom in or out on an audio waveform in the Source Monitor
You can zoom into an audio waveform in the Source Monitor to better identify locations for markers, In points, or Out points.
1. Double-click an audio clip in the Project panel to open it in the Source Monitor.
2. To zoom in horizontally, drag either end of the horizontal zoom bar that runs above the time bar in the Source Monitor.
The waveform of all channels, and the time bar, will expand or contract horizontally.
3. To zoom in vertically, do one of the following:
To zoom in on a single channel, drag either end of the vertical zoom bar that runs next to the decibel ruler on the right side of the
