How To Add an Additional Audio Track to Your Video

Ubuntu 15

In today’s digital era, videos have become a primary source of information and entertainment. Whether you’re a content creator, a marketer, or just someone who likes to experiment with videos, there may come a time when you need to add an additional audio track to your video. This could be for adding commentary, background music, or any other audio element that enhances your video content.

In this article, we’ll guide you through the process of adding an additional audio track to your video using various methods, depending on the file format. We’ll cover how to do this for MP4 files using MP4Box, for MKV files using mkvmerge GUI, and a universal method using avconv (or ffmpeg) command-line tool.

Quick Answer

To add an additional audio track to your video, you can use tools like MP4Box, mkvmerge GUI, or avconv (or ffmpeg) depending on the file format. With MP4Box, you can use a command-line tool to add a new audio track to an MP4 file. For MKV files, you can use the mkvmerge GUI to select and merge the video and audio files. If you’re working with both MP4 and MKV files, you can use the avconv (or ffmpeg) command-line tool.

Adding Audio to MP4 files using MP4Box

MP4Box is a command-line tool that you can use to manipulate MP4 files. To install the gpac package, which includes MP4Box, run the following command:

sudo apt-get install gpac

Once installed, you can add a new audio track to your video using the following command:

MP4Box -new -add OriginalMovie.mp4 -add Track2.mp3#audio:delay=300 Output.mp4

In this command:

  • OriginalMovie.mp4 should be replaced with the name of your original video file.
  • Track2.mp3 should be replaced with the name of your new audio file.
  • #audio:delay=300 specifies a delay of 300 milliseconds for the new audio track.
  • Output.mp4 is the name of the output file.

The resulting video file will contain both the original and new audio tracks.

Adding Audio to MKV files using mkvmerge GUI

For MKV files, you can use the mkvmerge GUI, which is part of the mkvtoolnix-gui package. To add an additional audio track:

  1. Open the mkvmerge GUI.
  2. Click “add” to select the video and audio files you want to merge.
  3. In the “Tracks, chapters and tags” box, select the new audio track and set its language and delay.
  4. Set the output filename.
  5. Click “Start muxing” to save the video file.

The resulting video file will contain both the original and new audio tracks.

Adding Audio using avconv (or ffmpeg)

If you’re working with both MP4 and MKV files, you can use the avconv (or ffmpeg) command-line tool. This tool is versatile and can handle multiple file formats. Here’s the command to add a new audio track:

avconv -i FIRST_INPUT_FILE -i SECOND_INPUT_FILE -c copy -map 0:v:1 -map 1:a:12 OUTPUT_FILE

In this command:

  • Replace FIRST_INPUT_FILE with the name of your original video file.
  • Replace SECOND_INPUT_FILE with the name of your new audio file.
  • Replace OUTPUT_FILE with the desired output filename.
  • The -map option specifies which tracks to copy from each input file.

The resulting video file will contain both the original and new audio tracks.

Conclusion

Adding an additional audio track to your video doesn’t have to be a complex process. With the right tools and commands, you can easily enhance your videos with extra audio elements. Whether you’re using MP4Box, mkvmerge GUI, or avconv (or ffmpeg), you can maintain the same video quality while adding a new audio track.

Remember, practice makes perfect. Don’t be afraid to experiment with different audio tracks and delays to find the perfect combination for your video. Happy editing!
