ADOBE PREMIERE PRO CS3 127 User Guide 2 In either the Project panel or Timeline panel, select the clips for which you want to know the total duration. The Info panel displays the number of items selected and the total duration of those items. This information is useful if you want to paste clips into a specific area and need to know the exact duration of the target area or of the source clips. Note: If you select noncontiguous clips in the Project panel, the Info panel displays the total duration of all the clips you select. However, if you select noncontiguous clips in a sequence, the Info panel displays the duration as a range, from In point of the first clip you selected, to the Out point of the last clip you selected. For the purpose of copying and pasting, the duration of a particular range is more important than the sum of all the clips' durations. If you copy and paste a noncontiguous group of sequence clips, the pasted clips will occupy the range as noted on the Info panel and the areas that you did not select will be black. Change clip duration The duration of a video or audio clip is the length of time it plays from its first frame (In point) to its last frame (Out point). Altering a clip's In or Out points changes the clip's duration. You can also set a duration for the clip, trimming the end of the clip to the specified duration. Still image durations can be set like other clips, except that still images can have any duration. 1 In the Timeline panel or Project panel, select a clip. 2 Do one of the following: • To change duration numerically, choose Clip > Speed/Duration, click the link button duration, type a new duration, and click OK. to unlink speed and • To change duration visually in the Timeline panel, move the Selection tool over an edge of the clip so that it changes to the Trim Out or Trim In tool, and drag the edge. If you are making the clip longer, the source clip must contain enough additional frames beyond its source In or Out point to accommodate the adjustment. If you want to trim a clip edge that's already adjacent to another clip, use the methods described in "Perform rolling and ripple edits" on page 111. If you set a clip in the Timeline panel to the duration you require, but you don't like where the clip begins and ends in relation to the adjacent clips, you can use the Slip tool to adjust the clip without changing the clip's program In and Out point or duration. (See "Perform slip and slide edits" on page 113.) See also "Change clip speed" on page 127 Change clip speed The speed of a clip is the playback rate compared to the rate at which it was recorded. Initially, a clip plays back at its normal, 100% speed. (Even if the source footage's frame rate doesn't match the project's, the project automatically reconciles the difference and plays back the clip at its proper speed.) Changing a clip's speed causes its source frames to be either omitted or repeated during playback, thereby making the video or audio play faster or slower. So naturally, a change in speed results in a corresponding change in duration. When you change the speed of a clip containing interlaced fields, you may need to adjust how Adobe Premiere Pro treats the fields, especially when the speed drops below 100% of the original speed. (See "Create interlaced or non-interlaced clips" on page 125.) April 1, 2008
