Today I needed to remove sound from an a flash video that was playing in the website. I was hoping that I would not have to get the DVD out and re-encode it for the web as this took me quite some time to get it to the required level of quality/size.

After a bit of searching with google I came across FFMPEG which turned made the task really easy.

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

-i is the input fil
-an disables the audio which is really important here.
-vcodec copy ensures that the codec of the input file is used for the output file.

output.flv is the name of the output file.

Hope that you find this useful! I know it saved me some time!
