In addition to being compatible with almost all devices, MP4 also has the ability to store multiple audio tracks. If you select the local language audio track when playing foreign video files, you can easily enjoy the video even if you don’t understand the foreign language. On the other hand, I think the auxiliary audio also needs to be removed from the MP4 audio track. For example, if you remove the auxiliary audio and keep only the local language, you can save yourself the trouble of selecting the audio each time you play it, and you can also reduce the file size of your video by removing unnecessary data.
In this article, we will show you how to remove sub audio from MP4 videos easily. The same method works if you want to remove auxiliary audio from videos like MKV and MOV, which can store multiple audio tracks just like MP4. Please use this method as a reference.
