How far you can drag depends on the type of clip and/or its duration. For example,
you cannot extend the length of a video or audio clip to exceed the duration of its
source file. Image, title, and color clips can be extended indefinitely. Zooming in
[+] on the Timeline will help in trimming a clip with accuracy.
Select Clip: Duration if you need extreme precision for the clip length. In the
Duration dialog box, type the desired length for the clip.
Trimming in the Source Window
One way which you can use to trim your videos is to use the Source window.
To trim a video in the Source Window:
1. Double-click a video clip in the Timeline.
2. In the Source Window, drag the Jog slider to the position you want as the mark-
in point and then press [F3].
3. Drag the Jog slider to the position you want as the mark-out point and then
press [F4].
4. Click Apply in the Source Window.
• Use the left-arrow or right-arrow key on your keyboard to go through your
video frame by frame. Each key press moves you one frame forward or back.
You can also hold down [Shift] and use the mouse to drag the Jog slider.
This feature is particularly useful if the video clip duration is very long or you
want to make precise trimming.
• This displays the clip duration. You can enter new values here to change the
length of the clip.
You can also use the Source Window to cut your video clips. Video Editor gives you
two options on how you can cut your video clips: Cut by Position and Cut by
Cue. Cut by Position slices the video clip based on the position of the Jog slider.
Cut by Cue slices the video clip based on the cue positions.
