Remove audio from video on Mac

Short answer

To remove audio from video on Mac, open the movie in QuickTime Player, choose Edit > Remove Audio, and save a separate copy. Yuzu Drag accepts MP4 and MOV files: drag the video, tap ⌘ for Tools, and drop on MUTE. It removes the audio track and keeps MOV inputs as MOV and MP4 inputs as MP4. Keep the source if you might need its sound later.

Shortcut note: These steps use the default drag shortcuts. While holding the files, briefly press and release ⌘ for Tools; tap it again for Actions. ⇧ opens Convert. If you changed the shortcuts in Yuzu, use your configured keys instead.

A silent copy can be useful for a visual demonstration, a background clip or footage with an unwanted conversation. Turning down the player's volume is not enough: another viewer can turn it back up. Remove the track from the delivered file, then verify that you attached that copy.

Start with QuickTime Player

Apple documents removing audio from a movie in QuickTime Player. Use this built-in option for an occasional clip you want to inspect as you work.

1. Duplicate the source in Finder if you need to protect your only original.
2. Open the working copy in QuickTime Player.
3. Choose Edit > Remove Audio.
4. Save the changed movie as a separate delivery file. If QuickTime asks for an export location or name, choose one you can identify later.
5. Close and reopen the saved copy.
6. Check its picture and confirm that sound has not been retained.

Be careful not to choose Remove Video, which is the opposite operation. If the command is unavailable, check whether the file is a movie that QuickTime can open and edit, and whether it actually contains an audio track. Renaming a file's extension does not make an unsupported movie editable.

QuickTime may save or export a different container from the input. Inspect the resulting file and the recipient's accepted formats instead of assuming a file called “silent” has the required extension. For a one-off job that plays correctly at the destination, this built-in workflow is enough.

Use Yuzu Drag for the Finder workflow

Yuzu's Mute tool accepts MP4 and MOV files and keeps the input container in the silent copy. The operation removes the audio track; it does not offer sound-by-sound editing.

1. Leave Yuzu Drag running and locate the source movie in Finder.
2. Begin dragging the movie.
3. Keep the drag active and tap ⌘ to show Tools.
4. Drop on Mute.
5. Wait for completion and locate the new silent movie.
6. Play the new file before sharing it.

Use ⌘ for Tools, not ⇧ for Convert. Changing the video container is a different task from removing the soundtrack. The Mute operation creates an output instead of changing your original clip, so identify the new file explicitly before attaching it to a message.

Check silence without relying on your speakers

First confirm that your player and Mac are not muted by playing a known audible file. Then open the exported silent copy. Otherwise, a system-wide mute could make the original seem silent and hide a mistake in the workflow.

QuickTime's Window > Show Movie Inspector can help you inspect the resulting media. Review the file's track information where available, along with playback. A different file name or smaller size is not proof that the audio was removed.

Check several points in the clip, including places that originally contained speech or music. Open the exact file you plan to send, not a previously exported test. If another app will publish it, review the uploaded version as well; an app may still be pointing to the original asset in its project.

Understand what this removes

Removing the soundtrack removes wanted and unwanted sounds together. If a clip contains a private conversation over useful music, this workflow does not preserve the music separately. Use an appropriate audio or video editor when you need selective sound editing.

A silent movie can still disclose information visually. Check visible names, documents, screens and captions before sharing. This tool does not alter those pixels. Do not treat a removed audio track as a complete review of sensitive content.

Keep the original outside the delivery selection until you are confident which version is which. For a client handoff, a distinct destination folder can be easier to review than several similarly named files together. Open the actual attachment from that folder as a final check.

A repeatable review example

Choose a short source clip with clearly audible speech at the beginning and another recognizable sound later. This is a suggested test case, not a measured result. Note where those sounds occur, create the silent copy, and inspect those same moments afterward.

Check duration, orientation and visible action as well as silence. Removing sound should not lead you to overlook an accidental wrong input or an incomplete delivery. No fixed file-size reduction is promised: the soundtrack's share of the original file varies.
