However, its compatibility can be a hurdle, as many devices and media players don’t fully support EAC3.

For those who are comfortable with command-line tools, FFmpeg offers a powerful alternative for converting EAC-3 to AAC within your video file. Here’s how you can do it:
Download and install FFmpeg on your computer. Make sure to set up the environment variables correctly so you can use FFmpeg from any command prompt window.
Open a command prompt window and navigate to the directory where your video file is located.
Run the following command to convert the audio track from EAC-3 to AAC:
ffmpeg -i input_video.mkv -c:v copy -c:a aac output_video.mkv
Replace input_video.mkv with the name of your video file and output_video.mkv with the desired output file name. This command tells FFmpeg to copy the video stream without changes (-c:v copy) and convert the audio stream to AAC (-c:a aac).
Once the process is complete, check the output file to ensure the audio has been converted correctly.
