How to Speed Up a Screen Recording on Mac
Speed up a Mac screen recording, cut dead time instead, keep narration easy to follow, and avoid the export limits that quietly undo your speed changes.
To speed up a screen recording on a Mac, open it in an editor that can change playback speed and save the result. QuickTime Player can trim a recording, but it has no speed setting you can save. In Screen Bolt, choose 1.5x or 2x from the speed menu in the timeline controls and export. That speeds up the whole video.
Before you speed anything up, check whether cutting would work better. A recording that feels slow usually has a few dead stretches: a page loading, a build running, you hunting for a menu. Deleting those often gives a better result than playing everything at 2x, especially when you're talking.
What QuickTime Player can and can't do
QuickTime Player comes with macOS and opens the .mov files you record with the Screenshot toolbar (⌘⇧5, Command-Shift-5). It has no speed setting that carries into a saved file.
It can trim the start and end:
- Open the recording in QuickTime Player.
- Choose Edit ▸ Trim (⌘T).
- Drag the yellow handles to the new start and end, then click Trim.
- Choose File ▸ Save to keep the change.
This removes a slow opening and ending. For cuts inside the recording, see how to trim a screen recording on Mac.
Using iMovie or another general video editor
If you want one section faster and the rest at normal speed in the exported file, you need an editor that can split a clip and change the speed of only one piece.
Apple's iMovie is a free general video editor for Mac. As of November 2026, the US Mac App Store listing requires macOS 26.6 or later, and the download is about 3.6 GB, so check your macOS version first. We don't document iMovie's controls on this page, so use Apple's own iMovie help for its current clip tools. It's a general video editor rather than a screen-recording tool. Anything specific to screen recordings is up to you.
Speed up the whole screen recording in Screen Bolt
We make Screen Bolt, a Mac screen recorder with a built-in timeline editor. Its speed setting applies to the entire video and is saved into the export.
- Open your recording in the Screen Bolt editor.
- In the timeline controls, click the speed menu. It shows the current speed, for example 1x.
- Under Playback Speed, choose 0.25x, 0.5x, 0.75x, 1x, 1.25x, 1.5x, 2x, 3x or 4x.
- Press Space to play the recording and check how it looks and sounds.
- Click Export in the toolbar. You can also change speed from the keyboard. L raises the speed by 0.25 (up to 4x) and plays. J lowers it by 0.25 (down to 0.25x) and plays. K pauses.
Watch out: this is not a preview-only control. Whatever the speed menu shows when you export is the speed of your exported file. If you used J or L to skim, set the menu back to 1x before exporting, unless you meant to speed the video up.
Screen Bolt can also open recordings made elsewhere, such as a QuickTime file, with File ▸ Create project from video.... Edits to an imported video are not saved as a project, so make your changes and export in one sitting. Imported videos also have no cursor data, so auto zoom and cursor effects only apply to recordings made in Screen Bolt.
Cut slow sections instead of speeding them up
Speeding up the whole video makes everything faster, including the parts that already had the right pace. Cutting removes only the waste, and in Screen Bolt it takes a few keystrokes.
Find the slow parts first
- Play the recording from the start.
- Press M each time you reach a slow stretch. This adds a marker at the playhead.
- Use [ and ] to jump to the previous and next marker.
Markers only help you find your place. They don't appear in the export.
Cut a range with In and Out points
- Move the playhead to the start of the dead time and press I to set the In point.
- Move to the end of it and press O to set the Out point.
- Click Cut I-O or press Delete (⌫).
You can also drag across a range on the timeline, then click the scissors button (Delete selected region). Other useful controls:
- S splits the clip at the playhead. You can then trim each half by dragging its edges, move it or delete it.
- ⌘Z undoes a cut. Undo history keeps 50 steps.
- Clear all cuts (the trash icon that appears once cuts exist) removes every cut you've made.
To avoid recording dead time in the first place, pause while something loads. The Pause button in Screen Bolt's recording bar removes the gap and keeps the screen, camera and cursor in sync. See how to pause a screen recording on Mac.
Speed ramps in Screen Bolt: current limits
Screen Bolt's editor also has speed ramps. Mark a range with I and O, open the Speed menu and choose a Slow Motion rate (0.25x, 0.5x, 0.75x) or a Fast Forward rate (1.5x, 2x, 3x, 4x). The ramp appears on the clip track and under Effects ▸ Speed Ramps, and it plays in the editor preview.
In version 1.11.5 (current as of November 2026), speed ramps are not included in the exported file. The ramped range plays at normal speed in the export. We'd rather you know that now than find out after rendering.
Until that changes, do one of these:
- Cut the slow range with In and Out points, as described above. For loading screens and waiting, cutting is usually the better edit anyway.
- Speed up the whole video with the speed menu, if every part works at the faster pace.
- Finish in another editor: do your cuts, zooms and styling in Screen Bolt, export at 1x, then change the speed of only that section in a general video editor.
To remove a ramp, right-click it on the clip track and choose Remove speed ramp.
Compare the methods
| Method | Whole video faster | Only part faster | Cost (as of November 2026) | Main limit |
|---|---|---|---|---|
| QuickTime Player | No | No | Free, built in | No saved speed change |
| Screen Bolt speed menu | Yes, 0.25x to 4x | No | Free version (watermark, 720p, 3-minute exports); Pro is $79 one-time | One speed for the whole export |
| Screen Bolt cuts | Shortens the video | Yes, by removing time | Same | Removes footage rather than speeding it up |
Keep narration usable when you speed up
Speeding up the video also speeds up your voice. These habits help:
- Listen before you export. Play the preview at the speed you plan to use. If you have to strain to follow your own voice, viewers will too.
- Cut silence and keep talking at 1x. Remove the stretches where nothing is said or shown, and leave narrated parts at normal speed.
- Try the smallest step first. For narrated videos, start at 1.25x and only go higher if the pacing still drags.
- Turn down system audio. Notification sounds and background audio get more distracting when sped up. In Screen Bolt's Audio panel, lower the System Audio volume, or right-click the system audio row on the timeline and choose Remove System Audio.
- Record the voice separately for fast visuals. If the screen needs to move quickly but the explanation doesn't, record without narration, speed up and export the screen video, then add your voiceover to that file. See how to add a voiceover to a screen recording.
Export your sped-up recording
Screen Bolt applies the speed and cuts when you export:
- Click Export in the editor toolbar.
- Under Format, choose MP4 (plays everywhere) or MOV (HEVC, smaller files).
- Under Quality, choose Original, 4K, 1080p or 720p. Presets larger than your recording are disabled.
- Check Save to (Desktop by default) and click Export, or press Return.
The summary line in the export sheet shows an estimated file size and the duration. At the same quality settings, a shorter video makes a smaller file. Finder shows the file when the export finishes. The export help page covers compression and frame rate.
Free version limits: exports are capped at 3 minutes and 720p, carry a "Made with Screen Bolt" watermark, and can't be GIFs. Recording length is unlimited, but the 3-minute check uses the full recording length, not the trimmed result. A 5-minute recording you've cut down to 2 minutes is still refused in the free version.
GIF (Pro only): a sped-up clip works well as a looping GIF. GIFs export at about 10 fps without sound. Clips over 60 seconds are refused, and for clips over 15 seconds you're asked to confirm.
If it doesn't work
- One section of the export plays at normal speed. That section has a speed ramp, which doesn't export in 1.11.5. Cut the range instead, or export at 1x and change that section's speed in another editor.
- The whole export is faster or slower than you wanted. You probably changed the speed with J or L while previewing. Set the speed menu to the speed you want and export again.
- "Recording Too Long for Free Export" after trimming. The free cap is measured against the full recording. Record shorter takes, or upgrade to Pro.
- Your edits to a QuickTime recording disappeared. Videos opened with Create project from video... or Open project... aren't saved as projects. Redo the edits and export before you close the editor.
- The narration is hard to follow. Use a lower speed, or keep 1x and cut the silent parts.
FAQ
Can QuickTime Player speed up a video? Not in a way you can save. QuickTime Player can trim and save, but it has no speed setting that changes the saved file.
Does speeding up a recording make the file smaller? Yes, at the same quality settings. A shorter video has fewer seconds of footage, so the file shrinks roughly in line with the new length.
Can I speed up just one part of a recording in Screen Bolt? Not in the exported file today. Speed ramps preview in the editor but don't export in 1.11.5. Cut that part, or export at 1x and speed up the section in another video editor.
How fast is too fast? If you're narrating, play it back at the target speed and judge whether your voice is still easy to follow. Silent footage, like a long install or a file copy, can usually go much faster or be cut entirely.
