Sometimes you may need to edit the volume of videos on iPhone. For example if the volume of video is too low, you need to increase volume of the video; on the other end, if the volume of iPhone video is too loud or if you want to add extra audio file or background music to it, you may need to lower the volume or perhaps mute the recorded audio or video. All you need is just a video editor which is capable of audio & volume editing, like iMovie, the stock movie editor for iPhone iPad and iPod touch. Other than this, many third party media editors can also do this job. Among these many video editors, Videoshop and FilmoraGo stand out for their ease of use and rich features. In this article, we will use them to demonstrate how to edit sound tracks and change volume of iPhone videos in different ways below.
