Capabilities

Tools 2

check_subtitles

Use this when the user asks whether an SRT or VTT subtitle file has problems, or wants a report before fixing it: overlapping cues, zero or negative durations, cues out of order, SRT numbering gaps, empty cues, cues too fast to read (characters per second above max_cps, default 20) and lines longer than max_line_chars (default 42). Takes one attached .srt or .vtt file or the subtitle text. Does not make a file and does not change the subtitles; fix_subtitles does that. Does not check spelling, translation or sync with the audio.

Discovered
fix_subtitles

Use this when the user wants to fix subtitle timing or convert subtitles: shift an SRT or VTT file earlier or later, convert it from one frame rate to another (23.976, 24, 25, 29.97, 30, 50, 59.94, 60), sync it on two cues, trim overlapping cues, give short cues a minimum duration, strip formatting tags, renumber, or convert SRT to WebVTT and back. Takes one attached .srt or .vtt file (or the subtitle text) and returns the fixed file and a CSV change log with old and new times per cue. Times are whole milliseconds, rounded half up. Does not listen to audio or find the right offset by itself, does not translate or edit the words, and does not read SSA/ASS files.
