Challenge 3: Showing the Wrong Section of Source Footage — Solution Walkthrough

The fitting edit type:

Slip.

Why, per this chapter's own material:

A Slip edit changes which portion of the source footage is shown
within a clip's own existing duration and position on the timeline,
without changing its length or position at all — exactly matching the
described situation: the clip is already at the right length and
position, but the wrong section of the original footage is currently
being displayed within it.

Why Ripple wouldn't be appropriate here:

Per this chapter's own material, Ripple trims a clip's own edge and
shifts subsequent clips to close the resulting gap — but this scenario
doesn't need the clip's own length changed or anything shifted on the
timeline at all; it needs the same-length clip to simply show a
different portion of the source footage, which Ripple doesn't
address.

Why Roll wouldn't be appropriate either:

Per this chapter's own material, Roll adjusts the shared cut point
between two adjacent clips, lengthening one while shortening the
other. This scenario isn't about redistributing time between two
clips at all — the clip's own length and position are already correct;
only the underlying footage being shown within it needs to change,
which is specifically what Slip does and neither Ripple nor Roll
addresses.

WHY THIS WORKS AS AN ANSWER
------------------------------
This exercise is a direct, practical application of this chapter's own
three-way trim distinction to a scenario matching Slip's own specific
definition, correctly ruling out Ripple and Roll by explaining what
each one actually changes instead.
