Whether Ripple mode is enabled or disabled it determines how the elements are trimmed. When Ripple mode is disabled, the overall duration of the sequence does not change when trimming. When you remove frames from the head or tail, it creates a gap (see Gaps in the Timeline). If there is an element located before of after the trimmed element, only a head or tail trim is possible. To slip & slide an element with Ripple mode disabled can only be done if there are handles at the head and/or tail of the shot. See Slip & Slide.
When Ripple mode is enabled, the overall duration of the sequence changes when trimming. Removing frames from the head or tail does not create a gap and the elements located before or after the trimmed element move in time (based upon the Ripple Start or Ripple End mode). You can slip & slide an element with Ripple mode enabled on any element when there are available handles.
If a layer is soloed, the Edit tools (Trash, Delete, Trim In/Trim Out, and Mark In/Out) default to 'Ripple End' behaviour, regardless of the Ripple Mode setting. If no layer is soloed, however, the Edit tools behave according to the individual Ripple Mode selected (Ripple Off, Ripple Start, or Ripple End) and apply to the active or visible layer that contains the focus point. For more information about Ripple Modes, see Trimming Ripple Mode
To trim an element:
- Enable Trim.
- Select a Ripple mode (i.e., Ripple Off, Ripple Start, or Ripple End). See Trimming Ripple Mode.
- Set the cursor on either the head or the tail of the element and the corresponding head or tail cursor appears.
- Click and drag the element.
- Dragging the element in the same direction of the head or tail cursor adds frames to the element.
- Dragging the element in the opposite direction of the head or tail cursor removes frames from the element.
Trimming Ripple Mode
There are three types of Ripple mode when trimming.
- Ripple Off
Trimming does not affect the duration of the timeline.
- Ripple Start
Trimming moves in time the element located before the trimmed element.
- Ripple End
Trimming moves in time the element located after the trimmed element.
