How to remove audio from a video on Mac instantly
Updated 2026-07-10 · Runs locally — nothing uploaded
Choose Remove audio; FFmix runs a stream-copy command that omits the sound track, so the picture is unchanged and the result is ready in seconds.

You do not need a timeline editor just to silence a clip. FFmix uses ffmpeg’s -an option to leave the audio stream out, while -c:v copy moves the video stream into the result without decoding and compressing it again. It is fast even for long recordings and does not soften the picture.
The result gets a -muted.mp4 suffix beside the source. That matters for privacy-sensitive dashcam, interview or screen recordings: the original remains intact, the derived copy contains no audio track, and neither file is uploaded.
Steps
- 1 Drop the video into FFmix and choose Remove audio.
- 2 Review the command: -an removes audio and -c:v copy preserves the video stream.
- 3 Confirm the operation.
- 4 Use the new -muted.mp4 file; the source keeps its original sound.
Advanced: canonical ffmpeg recipe
This is the canonical recipe. FFmix adapts encoder flags to the engine on your Mac, then shows the final command; the command shown is the command run.
ffmpeg -i "input.mp4" -an -c:v copy "input-muted.mp4"Drop a file and go — all local, nothing uploaded.
FAQ
Does removing audio reduce video quality?
No. FFmix copies the encoded video stream bit for bit and simply leaves the audio stream out of the new container.
Will the muted video be much smaller?
Usually only a little smaller because video uses most of the data. Use Compress video as a separate step if file size is the real goal.
Can I restore the audio later?
The new muted file has no audio track, but FFmix never changes the original, so keep the source if you may need the sound again.
