The below FFmpeg MKV to MP4 example shows you how to use FFmpeg to change video format without converting on Windows 10.

Step 3. In your Windows search bar, input “system environment variables” and open the best match result. Click “Environment Variables…” and select “Path” under the user variables section. Click “Edit…” and add the FFmpeg binary directory to the path, e.g.  C:\ffmpeg\bin. Then click “OK” to save the changes.

Step 4. Type “cmd” in your system search bar to bring up “Command Prompt.” Then input “ffmpeg -version” and press Enter to see if the configuration is done.

Step 5. Copy the path of the source video file. Then in the CMD, input “cd *the copied source path*” and press Enter to enter the file directory.

Step 6. Next, input “ffmpeg -i *example*.mkv -c copy *example*.mp4” and press Enter to start the single file remuxing.

Note: *example* means your file name.

for /R %f IN (*.mkv) DO ffmpeg -i "%f" -c copy "%~nf.mp4"

About Changing Video Container

A video container is a wrapper format used to store multimedia data, including video, audio streams, and sometimes subtitles. MP4, MKV, and AVI are the common video containers.

By saying changing video container, most people mean changing from one container format to another while keeping the data intact. This process is called remuxing or repackaging, and it is a lossless conversion. You’ll get the original video and audio quality after the process. And since the data won’t be re-encoded, the conversion will be done at the fastest speed (compared with the CPU-intensive transcoding). These are the reasons why many people prefer to change video container format only.

For changing video container without encoding, some requirements are to meet, including:

  • Make sure the parameters, including codecs, bitrate, resolution, aspect ratio, etc., remain the same;
  • No video editing before conversion.


We’ve just shown you how to change video container without encoding using two awesome programs. You can pick your preferred method based on your needs and start changing the format of a video right away. Hope you can find this article helpful. Thanks for reading. Have a good day!
