How to Combine Audio and Video in VLC in 2 Ways

By Cecilia Hwung | Last Update:

Being a multimedia framework written by the VideoLAN project, VLC acts as a free and open-source media player for multiplatform: Windows, macOS, Linux, BeOS and so on. It supports playing of diverse audio files (AAC, AC-3, DV Audio, FLAC, MP3, Speex, Vorbis, etc.), video files, and even DVD movies. What differs it from other players is that it is totally free.

Apart from these fundamental features as a media player, VLC can help users to perform somewhat editor-like task such as adding audio tracks to video. For example, if your source video file has no background sound, you can merge audio and video in vlc. Or if you are not happy about the original audio track, you can replace it with another audio file click on Play.

In the following paragraphs, we'll discuss how to add audio track in VLC as well as how to save the file afterward.

Part 1: How to Merge Video and Audio in VLC (No Permanent Save)

1. Go to Media > click Multiple Files, then a second window will pop up > click Add.

Drawbacks of This Method to Add Audio Track in VLC:

  • Problems such as no sound and subtitle errors also appear sometimes.
  • VLC can not help with the playback of M4V or M4A files on Mac computer.

Part 2: How to Add Audio Track in VLC (Saving as a New File)

If you want to save the video file with background music afterward, you need to disable the audio in the video, and then replace it with an external audio file. It is more complicated than the method above but works well. Now follow the instructions below and try to add a song to your video by using VLC.

1. Open Media > Convert/Save to add a video file to VLC. Click the Convert/Save button on the lower side to proceed.

Drawbacks of This Method to Merge Audio and Video in VLC:

  • It causes quality loss after re-encoding the video several times.
  • VLC lacks some crucial features like the adjustment of the audio codec, bit rate, sample rate, etc.
  • VLC cannot mix external audio with the original sound. It replaces the audio in a video.

Notes for the Methods Above

  • VLC is not primarily a video editing tool. It's possible to encounter synchronization or encoding issues when merging files, especially for critical projects.
  • The "Show more options" checkbox and "Play another media synchronously" option are crucial for adding the audio file.
  • The process might slightly vary depending on your VLC version.
  • Consider using dedicated video editing software like VideoProc Vlogger, which we will cover in the next part, if you need more control over quality and synchronization.

Conclusion

VLC Media Player offers basic functionalities to add or replace audio tracks in video files, but it has notable limitations. The "Open Multiple Files" method allows temporary playback with an added audio track but does not save the combined file. The "Convert/Save" method does enable saving the merged audio and video, but this process involves re-encoding, potentially leading to quality loss. Additionally, VLC lacks advanced audio editing features, making precise adjustments difficult.

For users seeking more refined audio editing capabilities, higher-quality output, and greater control over the final product, dedicated video editing software like VideoProc Vlogger can be a much better alternative. This tool provide advanced options for audio adjustments, effects, and export settings, ensuring a professional result without compromising quality. Therefore, while VLC can be a quick solution, professional video editors are recommended for serious audio-video editing tasks.
