Sliding an Element

Slip & Slide

Trimming adds head or tail frames to the element or subtracts head or tail frames from the element. You can trim using the trim cursors in the timeline canvas. For a specific trim cursor to appear, you must place the cursor over the required position within the element (i.e., head, tail, or middle section of the element). For example, when you place the cursor over the start of the element (the head), the trim head cursor appears.

The following editing changes are automatically updated in the Player:

• trimming

• slipping

• sliding

Note: You can also access some of the Multi-Layer Timeline features through the Colourist's Timeline. See Chapter 12, Colour Grading: Basics.

Trimming Cursors

The following cursors are used when trimming or slipping and sliding an element.

Trimming With Ripple Mode

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.

Note: 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.

1. Enable Trim.

2. Select a Ripple mode (i.e., Ripple Off, Ripple Start, or Ripple End). See Trimming Ripple Mode.

3. Set the cursor on either the head or the tail of the element and the corresponding head or tail cursor appears.

4. 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.

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.

Slipping an Element

Slipping simultaneously trims the head and tail of the element without changing its position in the sequence. The duration of the shot is not altered. Other elements in the edit sequence are not affected and the total duration of the sequence does not change. You can slip a single element or a selection.

Note: Slipping is a non-rippling action.

1. Enable Trim.

2. Position the cursor on the middle of the element that you want to slip.

   The slip & slide cursor appears.

   

3. Press the , (comma) key.

   The slip & slide cursor changes to a slip cursor.

   

4. Click and drag the element right or left.

   

Sliding an Element

Sliding changes a shot's position in the edit sequence without changing the head or the tail frames. It simultaneously slides the shot under the cursor and trims the head and tail of the surrounding gaps.

Note: Sliding can only occur if there is a gap before and/or after the element.

You can slide an element or a transition. See Transitions.

Note: When you slide the first or last segment of the element, it changes the total length of the sequence. When you slide the middle of the element, the sequence does not ripple.

1. Disable Trim.

2. Position the cursor on the middle of the element that you want to slide.

   

3. Click the element.

   The slide cursor appears.

   

4. Drag the element right or left.

   

Slip & Slide

Slip and slide changes a shot's position in the edit sequence, as well as the head and tail frames. The media of the element stays at the same position in the sequence, but the location of the element changes.

Note: Slipping and sliding can only occur if the element has available handles.

1. Click Trim.

   This enables the Trim mode.

2. Position the cursor on the middle of the element that you want to slip & slide.

   The slip & slide cursor appears.

3. Click and drag the element right or left.

There are three types of Ripple mode when you slip and slide.

Ripple Off--With Ripple Off, only the first and last shot of the Timeline and any shot surrounded by a gap, can slip and slide. The slip & slide operation adds a gap and changes the length of the edit sequence.

Ripple Start--The slip & slide operation moves in time the element located before the trimmed element and inserts a gap after the slip & slide element.

Ripple End--The slip and slide operation moves in time the element located after the trimmed element and inserts a gap before the slip & slide element.
