Part 1. How to Make FFmpeg Increase Volume on Windows?

FFmpeg offers a volume filter option, enabling you to change the volume of a video file or audio file easily. However, depending on your needs, the running commands have some differences. Let’s take a look at some examples.

Use FFmpeg to increase MP4 video volume

Step 1. Locate the media file that you want to change volume in File Explorer.

Step 2. Select the file path and type “cmd” in the address bar. Then press Enter on your keyboard to bring up Command Prompt.

Step 3. Then execute this command to increase the video volume:

ffmpeg -i Input_Filename.mp4 -filter:a "volume=2" Output_Filename.mp4

Important Note:

Input_Filename.mp4: Remember to change the “Input_Filename”, “Output_Filename”, and “.mp4” to your filename and video extension.
-filter:a "volume=2" : Use a value greater than 1 to increase the volume. For instance, volume=2 doubles the volume. If you want to decrease the file volume, use a value between 0 and 1. For example, volume=0.5 halves the volume.

Besides, you can also increase the volume by specifying it in decibels. For example, to increase your video volume by 3dB, use this command: (Bear in mind that sounds over 85dB can lead to hearing damage.)

ffmpeg -i Input_Filename.mp4 -filter:a "volume=3dB" Output_Filename.mp4

FFmpeg increase volume without re-encoding

If you want to change the volume of your file without re-encoding it, you can try this command:

ffmpeg -i Input_Filename.mp4 -filter:a "volume=2" -c:v copy Output_Filename.mp4
