How do I remove sound from a video file?

Hi.
How do I remove sound from a video file? I dont want the audio, I just want the video file with no sound.
Thanks.

Download Cinelerra.
When you import the video file into the editor, the audio tracks will be
separated out. You will be able to delete the audio tracks and render the video out to an .mpg file.

Open Movie Editor should also work.

It worked perfectly. Thank you Prospero2006.

Hi,

It can also be done with FFmpeg by using the -vn option:

-vn Disable video recording.

Hi Andrew. How would the code go?

Hi Andrew. How would the code go?

First determine the audio format:

ffmpeg -i input.flv

FFmpeg will give a full output, but here's the important part:

Stream #0.1: Audio: mp3, 44100 Hz, stereo, s16, 80 kb/s

Now that I know it is mp3, I can give the correct output file extension:

ffmpeg -i input.flv -acodec copy output.mp3

Using "acodec copy" will just copy the audio stream and not re-encode it. This preserves the quality. Sometimes you will need to use "-vn" as Andrew mentioned because some containers, mp4 and ogg for example, can take both audio and video.

Vidiot. I just now read that you want the video instead of the audio:

ffmpeg -i input.flv -an -vcodec copy output.flv

The "an" option tells FFmpeg to ignore the audio. Like my previous example, this just copies the video stream and doesn't re-encode.
