Edit Video on Mac with QuickTime: What You Can Do

Updated 9 November 2026 · Standard formula, shown below

Yes. QuickTime Player on a Mac can make simple edits to a video, including trimming its beginning or end, splitting it into clips, rearranging or deleting sections, and rotating or flipping the picture. It is useful for quick changes, but it is not a full video editor: it does not provide a multitrack timeline, titles, transitions, or detailed color and audio controls.

What QuickTime can edit

QuickTime Player is included with macOS and can handle a few common, straightforward changes without requiring a separate editing app. The controls are designed for simple clip-level work rather than building a complex project.

Trim: Keep a selected portion of a video and remove material before or after it.
Split and rearrange: Divide a movie into sections, remove unwanted sections, and move the remaining sections into a different order.
Rotate or flip: Correct a sideways or upside-down picture, or reverse its orientation.
Export: Save an edited movie as a new file or use Save to preserve the change, depending on the command and macOS version.

QuickTime is a good fit for shortening a recording, cutting out a pause, or correcting a camera orientation. For joining separate source files, adding captions, mixing music, or making a polished video with multiple layers, use an editor designed for those jobs.

Trim the beginning or end

Open the movie in QuickTime Player. If another app opens it, Control-click the file, choose Open With, then select QuickTime Player.
Choose Edit > Trim. A yellow trimming bar appears along the bottom of the playback window.
Drag the left and right handles to mark the portion you want to keep. Play the selection to check that the cut starts and ends where you intend.
Click Trim to remove the material outside the selection.
Choose File > Save or File > Export As, if available, to save the result. If you want to retain the untouched original, make a copy of the file in Finder before editing.

Trimming works well when the unwanted footage is at the start or finish. It is not the same as removing a middle section: for that, split the movie around the unwanted material and delete that section.

Split a movie and remove a middle section

QuickTime’s split controls let you divide a movie into clips. The exact controls can vary somewhat with the macOS version, but the general workflow is to position the playhead, split, and then remove or rearrange clips.

Open the movie and choose View > Show Clips if the clip strip is not visible. In some versions, the editing controls are presented through a different menu arrangement.
Move the playhead to the point where the section you want to remove begins, then choose Edit > Split Clip.
Move to the end of the unwanted section and choose Edit > Split Clip again. You should now have a separate clip between the two splits.
Select that middle clip and use the available delete command. Review the remaining clips and their order before saving.

For example, if a recording contains a long pause in the middle, split it once before the pause and once after it, then delete the isolated pause. Play across the cut: a cut made too close to speech can remove a word or make the audio sound abrupt.

Rotate, flip, or adjust the picture

To correct orientation, open the movie and use the appropriate command in the Edit menu, such as Rotate Left, Rotate Right, Flip Horizontal, or Flip Vertical when those options are available. Check the result in the playback window before saving. A rotation fixes the displayed orientation; it does not crop the picture or improve the original recording’s quality.

QuickTime’s basic editing tools should not be confused with image adjustments such as exposure, color grading, or stabilization. If the picture needs those changes, or if you need precise framing, use a video-editing app with those controls.

Save the edited video and protect the original

Saving and exporting are different. Save stores the current movie changes, while Export As, when offered, creates an output file using an available size or format option. Menu choices depend on the file and macOS version. Before relying on an edited copy, reopen it and check the beginning, end, and any cuts.

Make a Finder copy of valuable source footage before editing, especially if you are unsure whether a particular operation can be undone after closing the file.
Choose a practical export size for the intended use. A smaller output can be easier to share, but may have less image detail.
Keep enough free storage for the source and exported file. Exporting can create another copy rather than simply changing the original in place.
Do not assume that changing the file name or extension converts a video. Use an export option if you need a different output format.

Common problems and limitations

The edit command is unavailable: Confirm that a movie is open in QuickTime Player, rather than just selected in Finder. Some formats or protected media may not support the expected editing operations. Try opening a copy of the file, or use another editor that supports its format.

The cut is not exact: QuickTime is intended for basic edits, and the visible controls may not offer frame-accurate precision for every video. Zooming or seeking near the intended point and reviewing the cut can help, but a dedicated editor is preferable when exact frame timing matters.

The saved file is too large or looks different: Export settings can affect resolution and file size. Compare the exported result with the source, and avoid selecting a smaller size if preserving detail is important. A lower-resolution export cannot be made sharper simply by reopening it in QuickTime.

There is no timeline for multiple layers: QuickTime does not provide the kind of multitrack editing used to combine video, voice-over, music, titles, and effects. You can make simple changes to a movie, but that is not the same as assembling a full production.

When to use another editor

Choose QuickTime for a quick trim, a simple split, or an orientation correction. Use a more capable video editor if you need to combine unrelated recordings, add titles or subtitles, place music under dialogue, adjust color, apply transitions, or control individual frames and audio tracks.

For a basic project on a Mac, iMovie is a familiar option with a timeline and tools for combining clips and adding titles, transitions, and sound. Other editing apps offer different levels of control. Before choosing one, consider the file formats you use, how much editing precision you need, and whether you want a simple interface or advanced controls. QuickTime remains useful even if you move to another editor: it can still play many common video files and make quick, limited changes.

Frequently Asked Questions

Can I edit a video in QuickTime on a Mac?
Yes. QuickTime Player supports basic edits such as trimming, splitting clips, rearranging or deleting sections, and rotating or flipping a movie. Its tools are limited compared with a full video editor.

How do I cut out the middle of a video in QuickTime?
Split the movie at the start and end of the unwanted part, select the separate middle clip, and delete it. Play the edit to check the transition before saving.

Can QuickTime join two videos?
QuickTime can work with clips in a movie, but it is not a full project editor for combining and arranging separate source videos with layers and transitions. For a more reliable joined video, use a timeline-based editor.

Does trimming in QuickTime delete the original video?
It changes the movie you are editing, and saving can preserve that change. Make a Finder copy first if you need to keep an untouched original.

Why can’t I edit my video in QuickTime?
The file may be in a format or state that does not support the available operation, or it may not be open in QuickTime Player. Try a copy, check the app’s Edit menu, and consider an editor compatible with the file.
