How to fix one video overlapping another

You play back an edit and see the wrong shot covering the one you meant to use. It may look like a clip moved by itself, but often a second video is sitting above it on the timeline. Editors usually show the higher video track in front of the lower one wherever their clips happen at the same time.

Use the timeline to find which clip is on top, then move, trim, or remove only the part that should not be there. Save a copy first so you can undo the change without losing earlier work.

Find the overlapping clip

1. Pause playback where the unwanted image appears. Note the position of the playhead, the vertical marker showing the current time.
2. Look at the video tracks at that point. A clip on a higher track may cover footage on a lower track, even if the lower clip is still present.
3. Select the clip you suspect is covering the picture. Check whether its start and end extend across the unwanted section. If your editor shows a preview when you move the playhead, scrub a little before and after the overlap to confirm where it begins and ends.
4. Make a copy of the project before changing the timeline. If you cannot duplicate the project, save a new version under a different file name.

If several short clips make the timeline hard to read, zoom in around the playhead and inspect one track at a time. Do not delete a clip just because it looks misplaced. First confirm that it is the one shown in the preview.

What the result means

A different shot appears while the lower clip continues

The upper clip is probably covering the lower one. If the upper clip is an unwanted duplicate or overlay, remove it or move it to the intended time. If you still need it later, trim only the section that causes the problem.

The wrong image appears only for part of a clip

The clips overlap for only that time range, or an edit created a short extra segment. Zoom in and check the upper clip's edges. A very short piece can be hard to see when the timeline is zoomed out.

The picture changes but the sound seems right

The video and audio may be on separate tracks. Removing or moving a video clip can leave its audio in place, or shift the sound away from the matching picture. Check both sets of tracks before you make a change, and play the edit again with sound.

The picture is black or shows an earlier shot

The upper clip may be transparent, empty for part of its duration, or placed over a gap in the lower track. Check the clips immediately before and after the problem. A missing section can look like an overlap even when no second video is covering it. For a related timeline issue, see Why a timeline edit can leave a silent gap.

Fix the overlap without shifting the whole edit

1. Undo the last move. If the overlap appeared right after you dragged a clip, undo once and check the timeline. If the wrong change is undone, redo it and use the saved project copy instead.
2. Move the extra clip to its intended time. Drag it along its own track, not to a different vertical track. Watch the preview and the clip edges as you move it. Some editors snap clips to nearby edges, so zoom in if it lands a few frames away from where you expect.
3. Trim only the unwanted section. If the clip is useful before or after the overlap, split it at the beginning and end of the unwanted section, then remove that piece. Keep the playhead at the exact cut points and check that you selected the video segment rather than its linked audio.
4. Remove an accidental duplicate. If two copies begin at nearly the same time, identify which one belongs in the edit before deleting anything. If the clips are linked to audio, check whether removing one also removes its sound.
5. Check track order and visibility. If the clip should remain but should not cover another shot, see whether your editor lets you change track order, hide a track, or adjust the clip's opacity. Use these options only when you want the lower image to show through or the overlay to remain available.
6. Play through the cut. Start several seconds before the edit and continue several seconds after it. Look for a flash of the wrong shot, a gap, or audio that no longer matches. Save the corrected version once playback looks right.

Keep intentional overlays from becoming accidental ones

Two video clips can occupy the same time on purpose. This is how editors create picture-in-picture, titles over footage, and some transitions. The upper track is generally displayed in front, so an overlay can hide the main video if it is full-size and opaque. Moving it to a lower track may change what appears, but it can also disrupt the rest of the edit.

When you want a transition rather than one shot simply replacing another, use the transition method supported by your editor. Some editors create a transition when clips overlap on one track. Others require a transition control or separate tracks. If you are unsure, keep the original clips on separate tracks and make a test copy before changing their positions.

After fixing the timeline, save the editable project as well as any finished video you export. The project preserves the separate clips and tracks, which makes a later correction much easier than editing the exported video again.
