Video Volume Normalizer
1. About this app
This tool makes your video volumes consistent.
Creates a new file with _norm suffix
(example: video.mp4 → video_norm.mp4)
Original videos are not modified.
2. Files in this folder
Keep these files together:
VideoVolumeNormalizer.exe – the app
ffmpeg.exe – required engine for processing (same folder as the app)
install_ffmpeg_for_vvn.cmd – helper to set up ffmpeg.exe
README.txt – this guide
When sharing, send this whole folder as ZIP.
3. How to install FFmpeg (required)
Option A – Auto (recommended)
Right-click install_ffmpeg_for_vvn.cmd
Choose Run as administrator
If it says "FFmpeg is ready", you’re done.
Option B – Manual
If the script fails:
Download any Windows FFmpeg build.
From the downloaded package, get ffmpeg.exe.
Place ffmpeg.exe in the same folder as VideoVolumeNormalizer.exe.
4. How to use the app
Double-click VideoVolumeNormalizer.exe.
Click Add Files or Add Folder to select your videos.
(Optional) Set Output Folder:
Empty = save _norm files beside the original videos.
Set Target Loudness (LUFS):
Default -16 is good for most use cases.
Click Start Normalizing:
Watch the progress bar and percentage.
The border glow shows it’s working.
Look for the new files ending in _norm when it’s done.
5. If something doesn’t work
If you see an FFmpeg error:
Make sure ffmpeg.exe is in the same folder as VideoVolumeNormalizer.exe,
or run install_ffmpeg_for_vvn.cmd again as administrator.
If no files are processed:
Check that you added valid video files.
