I have a playlist of several music videos, but the videos have different loudness.
I want to play the playlist so that the loudness of each video would be the same, without the need to manually readjust the volume control for each video.
I do not want to modify the original video files to avoid any quality loss.
I know that VLC and WinAmp media players have a ReplayGain option that can read loudness information from file tags and readjust accordingly playback volume for each audio file, but it does not seem to work for video files.
Is it possible to accomplish such "per video file" volume normalization "on the fly" during playback of a playlist without modifying the original video files?
