You may decide to change the timing for a section of a clip already added to a sequence. Adjusting the start and end times of a selected clip is called Trimming.
What you learned: Trim clips on the Timeline
- You can extend or shorten the part of the clip included in the sequence, as long as there is footage available in the original clip. A small white triangle on either end of the sequence clip tells you if you’re already using the first or last frame of the original material.
- Drag the ends of clips as if you were resizing a window to extend or shorten them by trimming. You won’t be able to trim a clip over an adjacent clip.
- Use the Ripple Edit tool to trim clips without leaving a gap or to push adjacent clips later in the sequence.
- Use the Rolling Edit tool to adjust the timing of an edit between two clips, extending one clip by the same amount you shorten the other.
- To prevent unwanted changes, you can lock a whole track by clicking the padlock icon on the track header.
- Remember to choose the Selection tool when you have finished using the trimming tools.
What you learned: Trim clips in the Program Monitor
- View your sequence in Trim mode to make precise trim adjustments to your clips. To enter Trim mode in the Program Monitor, double-click the end of a clip.
- Drag on the video images in the Program Monitor to trim a clip, or use the buttons at the bottom of the panel.
- Change the way trimming works by Control-clicking (Windows) or Command-clicking (macOS) on the video images in the Program Monitor while in Trim mode, or in the Timeline panel. A red pointer means regular trimming, a yellow cursor means ripple trimming.
- Exit Trim mode by clicking an empty area in the Timeline panel.
When you insert clips, or ripple trim clips in a sequence, the timing of playback for clips later in the sequence is also changed. There are two ways to ensure clips on other tracks stay in sync, or are not affected by this timing change: Sync Locks and Track Locks.
What you learned: Make sure clips remain in sync
- To lock tracks, click the padlock icon on the track. No changes can be made to tracks that are locked.
- To enable and disable the Sync Lock for a track, click Toggle Sync Lock. When the Sync Lock is on, clips on the track will stay in sync with clips on a track that you’re ripple trimming or inserting.
- The audio and video parts of a linked clip remain together automatically, so they’ll stay in sync when you make adjustments. You can disable or enable Linked Selection in the Timeline panel by clicking the Linked Selection button at the top left of the Timeline panel.
