How can I strip the audio track out of a video file with FFmpeg?


You remove audio by using the -an flag.


ffmpeg -i $input_file -c copy -an $output_file

    I'm a bash and ffmpeg newbie but I put this answer together with some other pieces to create function ffsilent { ffmpeg -i $1 -c copy -an "$1-nosound.${1#*.}" } which you can use in your profile to quickly create a silent version of any video file. – Aaron Dec 16 '19 at 15:18

    @Aaron nice, but should be function ffsilent { ffmpeg -i "$1" -c copy -an "${1%.*}-nosound.${1#*.}" } or you'll end up with "file.mp4-nosound.mp4" when using it on "file.mp4". – Alexander Revo Jul 7 '20 at 8:52

You probably don't want to reencode the video (a slow and lossy process), so try:


ffmpeg -i $input_file -vcodec copy -an $output_file

(n.b. some Linux distributions now come with the avconv fork of ffmpeg)

    This didn't make any difference to me compared to the accepted solution. – nidi Dec 29 '17 at 0:49

    vcodec is an alias for -c:v, so specifically it'd copy the video stream only. The only data you're preventing with this would be subtitles, metadata, etc from what I can see. – Rogue Mar 8 '18 at 15:48
  • In other words, this solution can conceivably lose more information than the accepted solution. – Alex Feb 25 '20 at 15:12
avconv -i [input_file] -vcodec copy -an [output_file]

If you cannot install ffmpeg because of existing of avconv try that .


I put together a short code snippet that automates the process of removing audio from videos files for a whole directory that contains video files:

for input_file in $FILES
  file_name=$(basename $input_file)
  ffmpeg -i $input_file -c copy -an $output_file

I hope this one helps!
