Trim and Split Screen Recordings, Free in Chrome

Drag the trim handles to shave the awkward opening and the trailing “okay, I’ll stop it now”. Park the playhead and press S (or the Split button): the clip divides in two at that exact frame, and the new right-hand clip is selected.

The recording is the easy part. What comes out of it is a draft: a false start before you found your rhythm, a wrong click you talked your way past, forty seconds of a package installing while you hummed. Most browser recorders hand you that draft as the finished file. If you want it tight, you’re off to a separate editor. SuperchargeCapture puts a timeline directly under the preview, in the editor that opens the moment you stop recording.

Trim the Ends, Then Cut the Middle

The two most common fixes get the two most direct tools. Internal cuts you’ve already made stay exactly where they were.

One guard rail worth knowing: a split closer than 100 milliseconds to an existing boundary is refused, with a hint telling you why. That floor exists so you can’t accidentally produce a sliver clip too small to see or select.

Ripple Delete, With No Gap in the Export

Select a clip and press Delete. At export, the video plays straight across the cut, with no frozen frame or black gap. That’s a ripple delete, and combined with splitting it makes the standard middle cut three keystrokes: S, S, then Delete.

You can’t delete your way into an empty timeline; the editor always keeps at least one clip. And if a boundary deserves more than a hard cut, any clip after the first can take a fade-in, blending from black at the edit point.

The Timeline Works in Clips

The editor keeps the recording as clips on a timeline under the preview. Each clip can run at its own speed (0.5×, 1×, 1.5×, or 2×), so a dull stretch plays fast while the narration stays put. A one-click Trim silence pass detects the quiet stretches in the recording and removes them, so the dead air goes without you marking a single cut.

Undo Deep, Save Automatic

The history isn’t a token single-step undo. Every committed edit (a cut, a speed change, a caption, a blur region, a zoom) is one snapshot on a stack you can walk in both directions: Ctrl/Cmd+Z back, Ctrl/Cmd+Shift+Z or Ctrl/Cmd+Y forward.

Your work also survives you leaving. Edits autosave roughly half a second after each change, and reopening the recording restores the saved edits, with the undo history starting fresh. The honest caveat: uploaded assets (a background-music file or a custom background image) aren’t stored with the project, so those need re-adding after a reopen. Their settings are kept; only the file itself is asked for again.

Presets, Free

The editor ships three named presets: Clean, Cinematic, and Tutorial. Per-clip speed, silence trimming, and the presets are part of the free editor. No paid tier.

The Shortcuts

The same keys drive the work once it is in muscle memory:

Privacy

Editing happens entirely in your browser. The recording, the project file, and the undo history all live on your device. Nothing is uploaded, and there’s no account behind any of it. Export happens locally too; nothing is baked into the file until you ask for it.
