Subtitle quality workflow
Check subtitle drift, gaps, and truncation in SRT or VTT files
A structural review workflow for spotting suspicious timing gaps, overlap, repetition, long cues, and likely truncation before publication.
Target outcome
A review list of suspicious regions with enough context to inspect the audio or source transcript efficiently.
Work through the evidence
before the final claim.
- 01
Parse the timeline structure
Confirm cue ordering, start and end times, non-positive durations, overlap, large gaps, missing sequence, and malformed timestamps.
- 02
Look for text-shape anomalies
Flag repeated phrases, unusually long or short cues, sentence fragments, abrupt endings, and empty text without assuming every anomaly is an error.
- 03
Compare runs when available
Align the same source across transcription runs to find regions where timing, omissions, or repeated output changed materially.
- 04
Review the source at flagged regions
Use the structural findings to jump to likely problems, then make the editorial decision with audio, video, or authoritative source context.
Example input
A concrete first pass
A 42-minute interview SRT with a 19-second gap, three repeated cues, and the final sentence ending mid-word.
Reviewable output
A compact drift report identifying the timestamps, anomaly types, neighboring cues, and review priority.
The editor reviews a handful of suspicious regions instead of rereading the entire transcript blindly.
Important boundaries
What this workflow does not prove
- Structural checks cannot determine the intended spoken words.
- Music, silence, speaker changes, and editing choices can create legitimate anomalies.
- Human or authoritative source review remains necessary before publication.
