Controls in Trim Mode

The first thing you notice when entering trim mode is a whole new set of control buttons located along the bottom of the window between the two monitor displays (see Figure 4.9). These controls allow you to precisely control the number of frames you trim.

Figure 4.9. Trim mode buttons allow you to fine-tune edit points.


Here is how the controls work in trim mode, after you have selected the Target track and which side of the edit point you want to trim:

  • Previous Edit—This button allows you to jump back one edit point at a time without leaving trim mode. The keyboard shortcut is Ctrl-Shift-left arrow (Windows) or Command-Shift-left arrow (Macintosh).

  • Next Edit—This button allows you to jump forward one edit point at a time without leaving trim mode. The keyboard shortcut is Ctrl-Shift-right arrow (Windows) or Command-Shift-right arrow (Macintosh).

  • Trim Left 5 Frames—This button allows you to trim either side or both sides of the edit point (depending on what you have selected) five frames earlier in time (visually to the “left” looking at the timeline). This means that if the outgoing shot is selected, each click of the button moves your edit point in intervals of five frames back in time, shortening the clip's overall length. If the incoming shot is selected, each click of the button moves your edit point back in intervals of five frames at a time, revealing portions of the clip that occurred earlier relative to the portion of the clip that was previously displayed. This approach increases the clip's overall duration in the timeline. A combination of these steps occurs if you select both sides of the edit point. The keyboard shortcut is Shift-left arrow.

  • Trim Left—This button performs the same function as Trim Left 5 Frames, only in intervals of a single frame at a time. The left arrow key performs the same function in trim mode.

  • Trim Right—This button allows you to trim either side or both sides of the edit point (depending on what you have selected) forward in time (visually to the “right” looking at the timeline) in intervals of a single frame at a time. This means that if the outgoing shot is selected, each click of the button advances your edit point one frame forward in time, revealing portions of the clip that occurred later in time, extending the clip's overall length. If the incoming shot is selected, each click of the button moves your edit point forward one frame at a time. This approach, however, decreases the clip's overall duration in the timeline. A combination of these steps occurs if you select both sides of the edit point. The right arrow key performs the same function in trim mode.

  • Trim Right 5 Frames—This button performs the same function as Trim Right, only in intervals of five frames at a time. The keyboard shortcut is Shift-right arrow.

  • Play Edit—This button allows you to preview the edit, playing the movie a few seconds before the edit point, continuing a few seconds past the edit point, and then stopping. Use the keyboard shortcut 'to play the edit.

  • Cancel Edit—The greatest feature in nonlinear editing systems. Try something out. If you don't like the results, go back to where you started. This button works similarly to an undo feature. It reverts to the original position before the trim was made. You can also use the keyboard shortcuts Ctrl-Z (Windows) or Command-Z (Macintosh) to undo the step you took.

Another way you can trim an edit point is to enter a numeric value for the number of frames you want to trim. Do the following to trim using numeric input:

1.
Select which side(s) of the edit you want to trim.

2.
Click in the numeric value field located above the trim control buttons, as shown in Figure 4.10. If you roll the mouse over this area, the cursor changes to an I-bar, indicating a user entry field.

Figure 4.10. Enter the number of frames to trim an edit in the numeric value field.


3.
Enter the value (the number of frames) by which you want to trim the edit point. Enter only positive or negative whole numbers.

4.
Press Enter (Windows) or Return (Macintosh).

or

1.
Select which side(s) of the edit you want to trim.

2.
Use the numeric keypad on the keyboard to enter the value (the number of frames) by which you want to trim the edit point. Enter only positive or negative whole numbers.

3.
Click Enter on the keypad.

tip

Using the keypad saves you the time of having to click the entry field every time to perform a trim. The keypad automatically places the numeric entry in that field, allowing you to quickly tweak your edit points.


The last way to trim your edit points inside trim mode is to interactively trim them on-the-fly. To do this, place the cursor over one of the monitors (outgoing shot or incoming shot). Click and drag the mouse left and right (PCs), trimming your shot on-the-fly. Notice that as you drag the cursor back and forth, the in or out points you are adjusting update instantaneously. You can also manually drag the in or out points located below each monitor to trim one side of the edit point at a time (see Figure 4.11). To trim both sides of the edit point at the same time, click and hold the mouse button between both monitors (PCs). While still holding down the mouse button, drag the mouse to the right or left (depending on which direction you want to trim) to quickly trim your edit points on-the-fly. The numbers indicate the number of frames you have trimmed your shot since entering trim mode. A negative number indicates that you trimmed your clip earlier in time (to the left) from the original edit point. A positive number indicates that you trimmed your clip later in time (to the right) from the original edit point. Keep in mind that when you leave trim mode and then return, the number indicating the number of frames trimmed is reset to 00:00.

Figure 4.11. Manually trim each clip using the in and out points located beneath each monitor in trim mode.


note

Even if both sides of the edit point are highlighted, dragging the jog tread affects only the side of the incoming or outgoing clip you are moving.
