Remove a Moment From the Middle of a Clip

Quick answer: Open Edit this clip → Trim and switch the mode from Keep to Remove. Now the two handles mark the part to cut out: drag them around the bad moment, press Preview to watch the clip with that part skipped, and Save. What is before and after is joined with a straight cut, picture and sound together. It costs 5 credits and saves a new version; the original is kept.

Use it for: a hand that glitches for half a second, a dead pause between two lines, a moment where someone looks into the lens.

Keep and Remove are the same track read two ways

In Keep mode the handles frame what stays, so everything outside them is cut — that is how you trim the start and the end. In Remove mode the handles frame what goes, so the outside is kept and the two outer parts are joined. If the handles are still at the two ends when you switch to Remove, they jump to frame the middle third of the clip, so you start from a real selection; if you had already moved them, they stay where they are. Check the track after switching.

Step by step

Select the segment. Under the player, Edit this clip is open on Trim.
Click Remove.
Drag the left handle to just before the moment you want gone and the right handle to just after it. The player shows the frame under the handle as you drag.
Nudge with − and + (half a second a press) if you need to.
Press Preview: the clip plays with the removed part skipped, so you can hear whether the join lands well.
Press Save (5 credits). The new version appears in Version History as Trimmed.

What the join looks like

A straight cut: the frame before the removed part is followed directly by the frame after it. When the camera and the people are still, the jump is small; when someone is moving, it shows as a jump. Cut where the motion pauses — between two lines, at the end of a gesture, at a blink — and the join is hardest to notice. The sound is cut at the same points, so a word spoken inside the removed part disappears with it.

How much you can remove

Anything up to all but one second of the clip. When you drag the handles so far apart that less than a second would remain, the panel holds them back and says Keep at least 1s. If both handles sit together, nothing is removed. A cut that ends right at the start or the end of the clip is the same as trimming that end in Keep mode.

One cut per save

Each save removes one stretch. To remove two separate moments, save the first cut, then trim the trimmed version again for the second. Each save costs 5 credits, and the second trimmed version replaces the first — the segment keeps one trimmed version. How versions are kept.

When to fix it another way

If the glitch is in how the shot was framed or who is in it, removing it only shortens the problem. Change that shot in the storyboard and regenerate the segment. If the problem is a wrong word rather than a wrong moment, use Redub. Trim, AI visuals or Redub.

FAQ

Is there a crossfade at the join?

No, it is a straight cut. Choose a still moment for a clean join.

Does removing a part change the dialogue?

Only if a line was spoken inside the removed part; that sound goes with it.

Can I remove two parts at once?

No, one per save. Save, then trim the result again.

Will the segment be shorter in the episode?

Yes. Composite and download use the trimmed version while it is active, at its new length.

Take out the bad half-second

Switch to Remove, frame the moment, preview the join, save.
