How can a batch of videos in MP4 and other formats quickly remove the original audio and keep only the picture to meet our silent playback, secondary dubbing and other scenes? When dealing with teaching demonstrations, product demonstrations or public video playback, the background sound or unnecessary sound in the original video often needs to be removed to keep only the clear picture. Usually we need to put one video at a time into the editing software to cancel the sound manually. The operation will not only take a lot of time repeatedly, but also the efficiency will be very low when there are many video materials to be processed. Is there a stable and efficient way to delete the sound in MP4 video in batch and keep the original picture intact?

Why remove sound from MP4 video?
Removevideo noise
many videos may record all kinds of noisy sounds when shooting. These background noises may interfere with the audience's attention and make the video look unprofessional. After deleting the original sound, we can re-match it with a clean audio track or appropriate Background music, so that the viewer's experience will be much better.
Avoid copyright trouble.
if we accidentally record songs on TV or other people's copyrighted audio in our videos, we may be convicted of infringement after uploading them to the platform. Removing the sound in advance can avoid these copyright minefields, especially platforms such as YouTube, Bilibili or Tiktok, which can save a lot of energy.
Focus on video screen
some videos themselves do not need sound to modify, such as product display, operation demonstration or short video with subtitles, leaving a lot of original sound instead. After removing the sound, the video volume will become smaller, transmission and storage will be more convenient, and the viewer can concentrate on watching the details of the picture without being disturbed by sound.
