Add normalization levels

FallingSnow opened this issue · comments

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

Level 5

This level may alter the video/audio/subtitles in undesirable ways, use caution.

loudnorm is currently not supported by ffmpeg stable.

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