Welcome to the libass wiki!

If you want to know more about using libass and what to consider when authoring subtitles, see the “Informational Pages” section on the right.

If you’re doing libass development, the section of the same name documents some procedures and future plans.

Finally, you might be interested in the proposed ASSv5, but note that work on it is currently stalled. All related pages are grouped into the “ASSv5 (stale)” section on the right and the features list or specification draft are probably good entry points.
