When editing a video QuickTime MOV file, sometimes you may need to remove audio tracks bundled with it so that you can add a different audio track. Although a range of video editing programs can help you achieve this, I think Wondershare Filmora (originally Wondershare Video Editor) is worth trying. This program is cross-platform so that it can help you remove audio completely from the original MOV files with ease in both Windows and Mac.
Below is a detailed tutorial on how to remove audio from QuickTime MOV files in Windows (Widnows XP/Vista/7/8 included). If you're running a Mac, you can adopt Filmroa for Mac(Originally Wondershare Video Editor for Mac) to achieve the same. Before getting started, please download and install the right version for your operating system.
1 Import the source video files
After download and initiating this audio remover, choose between 16:9 and 4:3 ration rates. Then click the "Import" button to add the source video files to the program. You can also directly drag and drop your MOV video files to the user's album.
2 Remove audio from QuickTime MOV files
After importing the source video files, place them to the video timeline. Double click the target file to highlight it. Then right click and select "Audio Detach" option. The program will automatically separate the existing audio track from the original video file. You will find the separated audio track will appear in the Audio Timeline. To remove it, right click the audio track and choose "Delete".
Tip: This video editing tool also enables you to easily add your own sound track. To do this, just import the audio file as step 1 and then drag and drop it to the audio timeline. If the audio needs editing, double click it to adjust the volume, speed, pitch or add fade in/out effect in the pop up window.
3 Export or save the new files
Click the "Play" button in the right preview window to see the result. If you're satisfied, hit "Create" and you'll go to the export window. As you see, this program offers four output ways. In the "Format" tab, you can save the new work in all popular formats such as AVI, MP4, MOV, FLV and much more. You can also convert your video to a YouTube compatible format for online sharing in the "YouTube" tab and immediately upload it. Or burn a DVD disk in minutes to watch it on your home cinema.
