About this utility
How to use Subtitle Quality Auditor
Audit SRT or WebVTT cues for overlap, reading speed, long lines, excessive line count, and invalid durations.
What to provide
Paste subtitle cues. Timing and visible text are parsed locally; markup is never rendered.
- Paste, type, or drag and drop a supported text file into the input area.
- Review the input and the clearly labeled output behavior.
- Select “Run tool” or press Ctrl/Command + Enter, then copy, download, or move the result back into the first input for another pass.
What the result means
A cue timeline with duration, characters per second, preview text, and editorial issue flags.
Privacy and safety
This utility is loaded as browser code and processes your input only in this tab. OmniCastConverter has no upload endpoint and never stores your content, filenames, tokens, or secrets. Generated markup and code are shown as inert text and are never executed.
Limitations
- All input and output remains in this browser tab and is never uploaded or saved. Reading-speed and line-length thresholds are guidance and vary by language, audience, platform, and editorial standard.
