Best Ways to Remove Audio from MP4 in 2020

0 58

Video files are normally made up of two tracks: video and audio. Sometimes you might need to add a second video track for layering purposes, but this is less common than adding a second audio track. If you want to add background music or voiceover commentary, another audio track is exactly what you need. In other situations, it could be the other way around, and you’ll want to remove audio from MP4.

By removing an MP4 audio track, there are a lot of possibilities. Perhaps the existing audio has background noise, or you want to record commentary again without recording the video too. How do you go about doing this? We’ll explain the best ways to remove audio tracks from an MP4 file in this post.

2. Remove Audio from MP4 Online

If you want to avoid installing another piece of software on the computer, there’re plenty of online tools. AudioRemover is one of those tools, and as you can guess from the name, it’s specifically for removing audio. It’s not just for MP4 files, and it also works with AVI, MOV, and most other video formats.

As well as not requiring a download, you won’t have to sign up either. Head over to the website and follow our guide below.

  • Step #1 – Open an internet browser and go to the AudioRemover website.
  • Step #2 – Click the “Browse…” button and choose the MP4 file to remove audio from.
  • Step #3 – Press “Upload Video,” and as soon as the upload is done, it’ll begin removing the audio.

  • Step #4 – After AudioRemover processes your video, a checkmark will appear, and you can click “Download File” to retrieve the new MP4 without audio.

There are pros and cons when you remove audio from MP4 with an online tool. On the one hand, you can use it anywhere without redownloading software; on the other hand, there are upload limits. It’s rare that users will need to upload a file more than 500Mb, but it’s still a limitation.


3. Using VLC to Remove MP4 Audio

VLC Media Player is mostly known as a versatile and handy media player. It can play many more file types than Windows’ default media player can, and it’s also a media server. Use VLC to remove audio from a video by following these instructions:

  • Step #1 – Download and launch VLC Media Player.
  • Step #2 – At the top of the window, click the “Media” dropdown menu and then “Convert / Save…“.

  • Step #3 – On the new window, select the “File” tab and press “Add…“.

  • Step #4 – Locate and select the MP4 video, then click “Convert / Save” again.
  • Step #5 – Select an MP4 profile from the dropdown list.

  • Step #6 – Click the tools icon next to the profile.

  • Step #7 – In the “Encapsulation” menu, choose MP4/MOV as the video container.
  • Step #8 – Go to the “Video Codec” tab and tick “Keep original video track.”
  • Step #9 – Go to the “Audio Codec” tab and untick “Audio.”

  • Step #10 – Finally, click on “Save” and choose a save location for the new file.

This method is more complex and looks difficult, but it’s not as hard as it seems. VLC is a great media player and is a suitable way to remove audio tracks.


4. Using Shotcut to Remove MP4 Audio

Another video editing program that can also remove audio from MP4 is Shotcut. It’s free and available on Windows, Mac, and Linux computers.

  • Step #1 – Download and install Shotcut, then launch it.
  • Step #2 – Press the “Open File” button and select the MP4 file.

  • Step #3 – Shotcut will autoplay the video, so pause it before proceeding to click “Export.”

  • Step #4 – The export windows will appear. Next to “Format” choose MP4 and under the “Audio” tab check “Disable audio.”

  • Step #5 – At the bottom of the menu, click “Export File” and choose somewhere to save the file.

This process is relatively similar to using VLC, but a little bit easier. You could also convert the MP4 file to a different format during these steps.


5. Using Lightworks to Remove MP4 Audio

Lightworks is the next program we’ll be focusing on. Most users take Lightworks as a free video editor, and with the help of its built-in features, we can remove audio from MP4 flawlessly.

  • Step #1 – After installing Lightworks on your PC, run the program to begin.
  • Step #2 – Click “Create a new project” and type a suitable name for the video project.
  • Step #3 – Choose “Auto” as the video’s framerate setting and press “Create.”
  • Step #4 – Navigate to the “Local Files” tab and click “Places” to choose an MP4 file.

  • Step #5 – After the video is on Lightworks, click it and then click “Import.”

  • Step #6 – From the top menu, click “Edit” and drag the MP4 video down to the timeline.

  • Step #7 – All of the file’s tracks will appear. Track V1 is the video, and track A1 (and maybe A2) is the audio; some videos will also have A3 and A4.
  • Step #8 – Select A1 and A2, right-click on them, and click “Delete.” Similarly, if the video has A3 and A4 tracks, delete those too.

  • Step #9 – Now that there is only a video track, right-click the timeline and select “Export > H.264/MP4“.

  • Step #10 – Select a destination folder and give the video file a name, then press “Start.”

Again, it looks as though Lightworks has a difficult audio removal process, but in reality, it’s simple. If you follow these steps, then removing MP4 audio will be quick and easy.


6. Using MKVToolNix to Remove MKV Audio

For this final method, we’ve got MKVToolNix. This tool isn’t meant to remove audio from MP4 but is actually for removing MKV audio. MKVToolNix is a toolkit for handling MKV video files, which includes chapter management and various other basic useful tools.
