Example & formatting notes
Incorrect: 00:00:04,000 --> 00:00:03,000
Fix: Make the end timestamp later than the start timestamp.
A validator cannot infer the correct spoken words or audio timings. Review the original audio before changing any problematic cue.
Questions & answers
Does the subtitle file get uploaded? +
No. It is read locally by your browser and not sent to our servers.
Will this translate captions? +
No. It checks SRT formatting and time intervals; it does not translate or transcribe audio.
Can overlapping captions be valid? +
Some workflows intentionally overlap captions. This checker reports overlaps as warnings, not blocking errors.
