How to Mute a Video on Mac

The fastest way to mute a video on Mac is to open it in QuickTime Player and choose Edit > Remove Audio. Here's what that actually does to the file, how it differs from turning the volume down, and when it's the wrong move.

Mute a video on Mac with QuickTime Player

Open the clip and choose Edit > Remove Audio. Apple's description of the result is refreshingly literal: your file is now video only. There's a matching command in the other direction , Edit > Remove Video , which strips the picture and leaves an audio-only file, occasionally useful when you recorded a conversation and only wanted the conversation.

Note that this applies to the whole movie, not a selection. If you want one section silent, split the movie either side of that section first and work on the piece in between.

Muted is not the same as silenced

This distinction sounds pedantic until it costs you.

Turning the volume down , in a player, in a preview, on the machine , changes what you hear. The audio track is still in the file, unchanged, and it plays for whoever you send it to. People discover this by sending a clip they were certain was muted.

Remove Audio changes the file. The track isn't quiet, it isn't there. That's what makes it the correct choice when the reason for muting is that the sound must not reach anyone, and it's also what makes it worth being careful about. There's no reverse command inside a file that no longer has a track, so save a copy rather than overwriting the original whenever there's a chance you'll want the sound back.

Deleting the track to get rid of one sound is an expensive fix

A good share of muting isn't really about the sound at all. It's about something in the sound , a hum, a conversation in the next room, wind that ruined an otherwise fine take , and removing the whole track is the fastest way to make that go away.

It's also the most expensive. Deleting the audio deletes the voice with it, and a talking video with no voice needs everything the voice was carrying to be replaced by something else. If that's your situation, it's worth trying to clean the recording up before deciding it's unsalvageable.

When the sound has to go, the words don't have to

If the audio genuinely has to come out, the meaning still needs somewhere to live. Montaj transcribes the speech on your device and burns word-by-word captions into the picture, so a clip can lose its sound entirely and still say what it was saying, which is also how most short-form video gets watched regardless of whether you muted it.

Because the captions are part of the image rather than a separate track, they don't depend on a player or on anyone switching them on. Everything runs on your machine, with nothing uploaded. Mute a video on Mac in QuickTime Player when it needs to be silent; this is what stops silent meaning empty.
