Steps to convert H.264 Files to MP4 using FFmpeg:

Step 1: Obtain the FFmpeg executables. On your web browser, navigate to https://www.ffmpeg.org/download.html and download the packages or executables for your platform. Since I am on Windows I will therefore download the Windows-specific files.


Step 2: Locate the FFmpeg executable. Although the milestone may vary, you must have downloaded a compressed file containing the FFmpeg files. All you need to do is extract the contents and then open the folder containing the executables.


Step 3: Open a command-line window or command prompt in the folder containing the executables. On Windows 11, simply right-click inside the folder (other versions of Windows may require you to hold down the “Shift” key on the keyboard), and select the “Open in Windows Terminal” option (the option name also varies depending on the version of Windows). Once you do so, you should see a terminal window pop up.


Step 4: Add the H.264 file in the folder containing the FFmpeg executables. Simply copy and paste the source file in the indicated folder. In our case here, we will be using an MKV file that utilizes the H.264 codec.


Step 5: Convert the H.264 file into MP4. Using the earlier opened command-line window, type the command below. Remember to substitute the “inputfilename” with the source filename of your H.264 file and the “outputfilename” with the name you want for the target MP4 file.

./ffmpeg.exe -i inputfilename.mkv outputfilename.mp4

For instance, mine will be as below. I am keeping the same filename for the output too.

./ffmpeg.exe -i sample.mkv sample.mp4

Once you have the command ready, hit the “Enter” key on your keyboard.


Once the conversion process is done, you should be able to find the converted MP4 file in the same directory as the source file.
