Each level carries on to the next. This means level 3 includes all normalizations from level 1 to 3.
Level 0
- No normalization of any kind is applied
Level 1
- Videos are auto cropped
Level 2
- Subtitle Title normalization for subtitles streams already without a title
- Audio Title normalization for audio streams already without a title
- Language normalization detected from title if already exists. Search title for language and apply it to language tag in metadata.
Level 3
- Audio Normalization - “simple” audio RMS-based normalization to -2.0 dBFS
- Deinterlace videos.
Level 4
- Audio Normalization - loudnorm audio normalization
Level 5
This level may alter the video/audio/subtitles in undesirable ways, use caution.
- Audio Normalization - dynaudnorm audio normalization

loudnorm is currently not supported by ffmpeg stable.

These systems have been reworked with the 0.5.2 update and is no longer relevant.
