How can I incorporate an audio track into an MKV video file using available tools on Ubuntu?

I’m trying to edit a video file and really need some help. I have this MKV video that I absolutely love, but I want to make it even better by adding an audio track to it. The thing is, I’m using Ubuntu, and I’m not sure what’s the best way to go about this. I’ve heard there are plenty of tools out there that could help, but I’m kind of lost when it comes to figuring out which one to use.

Like, do I need to dive into the command line for this? I’ve tried that before, but it felt a bit overwhelming. I guess I’m looking for something a bit more user-friendly – maybe a GUI tool that doesn’t make me feel like I need a degree in computer science.

Also, I’ve seen references to tools like FFmpeg, which I know most tech-savvy people swear by, but I am not quite sure how to use it for adding audio to video. Is it really as complicated as it sounds, or are there some simple commands that I can follow? I mean, what’s the basic step-by-step process if I do decide to go that route?

If there are other applications, like Avidemux or something similar, I’d love to hear about those too. I want to make sure the audio syncs properly with the video, so any tips on how to avoid those awkward delays or overlaps would really be appreciated.

I know this might seem like a straightforward task for those who have done it before, but for someone still trying to get the hang of video editing, it feels a bit daunting. If you’ve done this kind of thing before on Ubuntu, or if you have any tips or recommendations on how to get it done smoothly, I would be super grateful for your advice! Thanks a bunch in advance!

    1. Video Editing Help on Ubuntu

      Adding an Audio Track to MKV on Ubuntu

      If you’re looking to add an audio track to your MKV video on Ubuntu, you’re in luck! There are several tools that can help you with this, including both GUI options and command-line tools. Let’s break it down.

      Recommended GUI Tools:

      • Avidemux: This is a user-friendly application for simple video editing tasks. You can easily add an audio track without getting too complex. Just load your video, go to the “Audio” menu, and select “Add Audio Track.” Then you can save the output with your desired format.
      • Shotcut: Another great choice! It’s a free, open-source video editor that supports a wide range of formats. Just drag and drop your MKV file, add the audio track, and export the video. Its interface is quite intuitive, so you shouldn’t feel overwhelmed.

      Using FFmpeg (if you dare!):

      Okay, so if you want to try FFmpeg, it sounds scary but it’s actually not too bad. Here’s a simple step-by-step to add audio:

      1. First, install FFmpeg if you don’t have it yet. You can do this using the terminal:
        2. sudo apt update && sudo apt install ffmpeg
      2. Once it’s installed, open the terminal and navigate to the folder where your video and audio files are located.
      3. Then, use this basic command (replacing `` and `` with your file names):
        4. ffmpeg -i input.mkv -i audio.mp3 -c:v copy -c:a aac -strict experimental output.mkv
      4. This command combines the video and audio into a new file called `output.mkv`. The `-c:v copy` part just copies the video without re-encoding it, which is quick and keeps the quality. The rest deals with the audio codec.

      Tips for Syncing Audio:

      To avoid any awkward delays or overlaps, make sure:

      • Your audio file isn’t longer than the video file. Cut it down if necessary using a tool like Audacity.
      • Check the sample rates of your audio and video. You might need to adjust them to match, which can usually be done in the settings of your audio editing tool.

      So, that’s a quick guide to get you started! You can definitely do this without needing a tech degree. Just pick a tool you’re comfortable with and dive in. Good luck, and have fun editing!



    2. To add an audio track to your MKV video file on Ubuntu, you have a couple of user-friendly options. If you prefer a graphical user interface (GUI), Avidemux is a great choice. It’s a straightforward tool that allows you to easily load your MKV file, then navigate to the “Audio” menu where you can select “Add Audio” to include your desired audio track. Once you’ve added the audio, remember to adjust the sync if necessary by using the provided timeline tools. Avidemux makes it relatively simple to export your final video, ensuring that the audio syncs properly with the video without any command line complexity.

      If you decide to explore FFmpeg, while it might seem daunting at first, it’s quite powerful and can achieve your goal using simple commands. Firstly, install FFmpeg through your terminal with `sudo apt install ffmpeg`. Once installed, you can use a command like `ffmpeg -i input.mkv -i audio.mp3 -c:v copy -c:a aac -strict experimental output.mkv` to combine your video and audio tracks. This command specifies the input files (the MKV video and the audio file), tells FFmpeg to copy the video stream without re-encoding it, and encodes the audio to AAC format. By using these tools, you’ll be able to edit your video seamlessly, avoiding common sync issues and making the process less daunting.
