Slide Edit

A slide edit repositions a clip within a timeline by moving its temporal location — where it sits in relation to surrounding clips — while keeping the clip's in and out points (and therefore its content and duration) exactly the same. When you slide a clip, you're moving the same section of footage to a different point in time in the sequence. The neighboring clips adjust to accommodate the slide: the clip before the sliding clip gains or loses duration at its out point, and the clip after gains or loses duration at its in point — both giving up or gaining time as the sliding clip occupies a new position. The total sequence duration stays the same.

The contrast with a slip edit clarifies the distinction. In a slip edit, the clip stays in the same position in the timeline but the portion of the source footage shown by the clip changes — you're moving the content through a fixed window. In a slide edit, the content stays the same but the window's position in the timeline changes. Slide: move the clip's position, keep the content. Slip: keep the clip's position, move the content. Both are "silent" edits in the sense that the total sequence duration doesn't change — they're repositioning operations within an already-assembled sequence.

For editors refining a cut, slide edits are most useful for adjusting the timing of B-roll over a dialogue track. If you have a cutaway clip showing a product detail that you want to appear slightly earlier in the sequence — perhaps to coincide with a moment in the dialogue when that detail is referenced — sliding the cutaway clip earlier repositions it in time while keeping the same portion of footage showing. The dialogue track is unaffected, and the surrounding B-roll clips absorb the positional change by gaining or losing a small amount of duration. Slide edits are a precision repositioning tool for fine-tuning the synchronization between visual cutaways and audio content in an interview-driven edit.
