VLC Media Player is a versatile, free tool that can do more than just play your favorite movies and songs. One of its lesser-known but incredibly useful features is the ability to merge audio and video files. Whether you’re creating a music video, adding a voiceover to your footage, or simply fixing audio issues in a video, VLC can help you accomplish these tasks without the need for expensive editing software.
In this guide, we’ll walk you through the process of merging audio and video in VLC, troubleshoot common issues, and discuss alternative options for more advanced editing needs.
Introduction to Merging Audio and Video with VLC
VLC Media Player, developed by the VideoLAN project, is an open-source multimedia player that supports a wide range of audio and video formats. Its popularity stems from its versatility, ease of use, and the fact that it’s completely free.
Benefits of using VLC for audio/video merging:
- No cost: VLC is free to download and use.
- No ads or spyware: Unlike some free software, VLC is clean and respects your privacy.
- Wide format support: VLC can handle almost any audio or video format you throw at it.
- Cross-platform compatibility: Available for Windows, macOS, Linux, and mobile devices.
- Simple interface: Easy to use, even for beginners.
Preparing Your Files
Before you start merging, it’s crucial to properly prepare your files:
Supported file formats:
VLC supports numerous formats, including:
- Video: MP4, AVI, MOV, MKV, FLV
- Audio: MP3, WAV, AAC, FLAC
Organizing your files:
- Create a dedicated folder for your project.
- Name your files clearly (e.g., “main_video.mp4”, “background_music.mp3”).
- Ensure your files are in a VLC-supported format.
Importance of file quality:
- Use high-quality source files for the best results.
- Be aware that merging may result in some quality loss due to re-encoding.
Method 1: Merging Audio and Video for Playback
This method allows you to play a video with a new audio track without creating a new file.
- Open VLC Media Player.
- Go to Media > Open Multiple Files.
- Click Add and select your video file.
- Check “Show more options” and “Play another media synchronously“.
- Click Browse next to “Play another media synchronously“.
- Select your audio file and click Select.
- Click Play.
- Go to Audio > Audio Track and select the new audio track (usually Track 2).
Tips for syncing audio and video:
- Use the “Track Synchronization” tool (Tools > Track Synchronization) to adjust timing.
- Enter positive values to delay audio or negative values to speed it up.

Method 2: Merging and Saving Audio and Video
This method creates a new file with the merged audio and video.
- Open VLC Media Player.
- Go to Media > Convert / Save.
- Add your video file and click Convert / Save.
- Click the wrench icon next to Profile.
- In the Audio codec tab, uncheck “Audio” to remove the original audio.
- Click Save, choose a destination, and click Start to create a video without audio.
- Repeat steps 2-4 with the new video file.
- Add your audio file as in Method 1.
- Instead of Play, choose Convert / Save from the dropdown.
- Enable audio in Profile settings.
- Choose a destination, add “.mp4” to the filename, and click Start.
Saving options and considerations:
- Choose an appropriate output format (MP4 is generally a safe choice).
- Be aware that this process may take some time, depending on file sizes.
- Ensure you have enough disk space for the new file.

Troubleshooting Common Issues
Audio syncing problems:
- Use the Track Synchronization tool to fine-tune timing.
- If sync issues persist, try re-encoding your audio to match the video’s frame rate.
Quality loss:
- Use high-quality source files.
- Minimize the number of times you re-encode the video.
- Experiment with different output settings to find the best balance of quality and file size.
File compatibility issues:
- Ensure both audio and video files are in VLC-supported formats.
- If issues persist, try converting files to more common formats (e.g., MP4 for video, MP3 for audio) before merging.
Audio quality issues:
If you’re experiencing issues with audio quality, such as reverb, you might need to remove reverb from audio before merging. This can be done using specialized audio editing software.
Limitations of Using VLC for Merging
While VLC is a great free option, it has some drawbacks:
- Limited editing features compared to dedicated video editors.
- Potential quality loss due to re-encoding.
- Cannot mix new audio with original audio; it replaces it entirely.
- May crash with very large files or complex merging tasks.
If you find VLC’s limitations too restrictive, you might want to explore VLC alternatives for more advanced audio and video editing capabilities.
