Ripple, roll, slip, and slide

Trimming is the grammar of timing. Ripple changes duration and shifts later material. Roll moves a shared boundary. Slip changes the source window inside a clip. Slide moves a clip while trimming its neighbors.

What you’ll be able to do

Choose the trim operation that matches the desired timing change.

Work through it

  1. Arrange three clips with unused handles and duplicate the timeline. Enter Trim Edit mode and hover near edges until the cursor indicates the intended trim.
  2. Ripple the end of the first clip by a second. Note the new total duration and the movement of later material. Undo.
  3. Roll the boundary between two clips. The outgoing clip gains what the incoming clip loses, preserving their combined duration. Compare the viewer’s outgoing and incoming frames.
  4. Slip the middle clip to choose different source frames without moving it in time. Then try a slide operation and inspect both neighbors. Undo between demonstrations.

A mistake to avoid

Trim availability depends on source handles and neighboring content. If a trim stops, check whether you have reached the media boundary rather than forcing a workaround.

Your turn

Make one deliberate example of each trim. Record which changes timeline duration, which changes source content, and which changes a clip’s position.

QUICK KNOWLEDGE CHECK

Which operation changes source frames while preserving clip position and duration?
