#Sub Levels

Sub levels is how nekoBT attempts to categorize the quality of a release's subtitles. The higher the sub level, the more extensive the work put into the subtitles.

The keywords "SHOULD" and "MUST" below are to be interpreted as described in RFC 2119.

  • "MUST" means it's a hard requirement.
  • "SHOULD" means it's not a requirement, but there are very few valid reasons not to have it.
    • Example: A valid reason for not having TS would be that there are no signs in the episode.

The sub levels are as follows:

  • Level 0 (L0): Official
    • These are official subtitles taken from a source.
      • Examples: Netflix, Crunchyroll, Blu-ray, etc.
    • The following modifications are considered minor, and still count as L0:
      • Changing the font style/size/color.
      • Shifting subtitle timing (this also includes removal of commercial breaks, etc).
  • Level 1 (L1): Slight Modifications
    • Any modified subtitles that goes further than the modifications stated above.
  • Level 2 (L2): Small-scale Fansubs
    • SHOULD have at least two of the following: ED, TS, and Song Translation
    • or MUST be an original translation (OTL).
  • Level 3 (L3): Full-scale Fansubs
    • SHOULD have all of the following: ED, TS, Song Translation, fixed timing issues.
    • MUST have QC.
  • Level 4 (L4): Full-scale Batch
    • For content with multiple episodes (e.g., TV series):
      • MUST meet L3 requirements for all episodes.
      • MUST contain all episodes in a season.
    • For movies or single-episode content:
      • MUST meet L3 requirements.
      • MUST be an improvement over other L3 releases of the same content.
    • SHOULD contain batch fixes, such as typos, missing typesetting, etc.

Here's a flow chart to help you categorize your release's sub level:

Yes

No

Yes

No to both

Yes

Are the subtitles untouched or only had a main style change from their official source?

Level 0

Have you done at least 2 of the following:
ED, TS, Song Translation? Or is it an OTL?

Did you do ED, TS, Song Translation,
fix timing issues, and done a QC pass?

Level 1

Is this a release for TV or a movie?

Level 2

Do all episodes have the same quality, and it contains all episodes in a season?

Level 4

Level 3

Does this release improve upon other L3 releases of the same content?

Level 4

Level 3

#Appendix

  • ED: Editing — making changes to the script to make it read well.
  • TS: Typesetting — turning foreign signs (text on screen) into your language.
  • QC: Quality Control — checking everyone's work for errors, typos, etc.
  • TLC: Translation Check — checking the translation for accuracy.
  • Song Translation: Adding translated lyrics for the songs (possibly with or without karaoke effects).
  • OTL: Original Translation — translation made from scratch for the project (rather than editing an existing one).
