A few things
worth knowing.
What does the SRT cleaner repair?
Output is sequentially renumbered. You can remove empty cues, remove exact duplicates with identical timing and text, and reflow caption lines to a preferred length.
How precise is the diagnostic report?
Each issue names its source file, original 1-based cue ordinal and source line, with an issue code, severity and explanation. File-wide warnings use a blank cue number.
Are overlapping subtitles deleted?
No. Overlaps can be intentional, so the cleaner reports them and preserves timing. Fix individual overlaps in your subtitle editor when necessary.
