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. You could probably argue converting the video to GIF is more appropriate, but GIFs can be larger and more taxing on the device. You also cannot pause or control animated GIFs.
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.
