Remove Audio From Video
Sometimes I want to display live motion without the audio, since the audio is either bad quality or it's just extra load, which is especially important on mobile.

The better solution may be to remove the audio from a video:
./ffmpeg -i MusicVideo.webm -vcodec copy -an MusicVideoNoAudio.webm
The -an option removes the the audio from the input file, producing a video without any audio. The sample file below went from 5.4MB to 4.1MB and now you don't hear the annoying wind in the background.
