[Feature Request] Volume Normalization for Music Video

[Rowan-Underwood]

I know we already have Volume normalization for music in Plex; however, for music videos there doesn’t seem to be any option out there short of pulling out all the audio tracks, using a regular audio normalizer, then putting the audio back into the video.

To be clear, I am talking about volume normalization (normalizing separate files across an Entire Library so you don’t end up with a really loud/or quiet one at random) NOT volume leveling within a single track. This is absolutely essential for playing a collection that covers a large time period as I guarantee there will be a ton of different volumes in there. I really don’t understand how this doesn’t drive more people insane than just me. Makes a collection almost completely unusable.

More than a decade ago, I used aacgain on M4A, as well as the occasional MP4 video w/ an AAC audio track.

GitHub - dgilman/aacgain: Adjust gain (volume) of aac or mp3 files without reencoding them

I just discovered that this exists:

GitHub - kevinlekiller/mkvrg: Apply replaygain tags to matroska files without remuxing (gain is calculated using ffmpeg and tags are applied using mkvpropedit).

Even if you can encode replaygain-style values, will your playback devices observe those tags? I think mpv-based players might?

I think it’s worth checking if foobar2000 can calculate & save replaygain values in video files.
