- All info is user submitted, so quality varies (much like online subtitle sites).
- Given the amount of different DVD/Blu-ray releases based region, various cuts, etc, even if the info is accurate, it may not match your media.
- As @OttoKerner mentions, the database has been read-only for for some time, so info for new releases will not be available (The original chapterdb.org went offline in 2019. There have been no updates since.).
However, I can usually find a decent match.
- The text format download can be imported into the Chapter Editor in MKVToolNix (Load movie into Chapter Editor, choose Append Chapters from Chapter Editor menu).
- If the timing is off by a consistent amount, it is easy to adjust using Chapter Editor (load movie into Chapter Editor, right click on
Edition Entry, choose Additional Modifications then Shift Start/End timestamps). - If all else fails, you can sometimes find the chapter names and just edit them in manually (if your movie has existing chapter markers but not names). I have not found a way to import just chapter names and keep existing timings.
