1. First, we turn on Niwowo's all-around video converter and add a video that needs to be muted.

2. Click the Inverted Triangle button behind the preset scheme to select the format, and click the Tools button to enter advanced settings for detailed parameter setting.

3. Click the Advanced Settings button to enter the Advanced Settings window, and you can see that there are two options, video and audio, corresponding to the detailed parameter settings below. We just need to remove the check box behind the audio, so that the output video is a video with only video images and no sound.
