Workflow notes
How this page helps video creators
Useful for copied captions
This is especially helpful when captions come from exports, web pages, or editor copy-paste workflows.
How it works
A simple subtitle repair workflow
Paste your subtitle file
Drop in SRT or simple WebVTT text. Use the sample button if you want to test the controls first.
Run the focused action
Convert formats, shift timing, clean blocks, or create a translation prompt without leaving the page.
Review and export
Check caption count, duration, timeline density, then copy or download the result for your editor.
Format support
Built for common creator subtitle files
Privacy model
The current MVP processes pasted text in the browser. There is no server upload or account flow.
Supported input
Works best with SRT and simple WebVTT cues that contain standard timestamp lines.
Human review
Always check names, line length, timing, and cultural wording before publishing translated captions.
Known limits
Advanced VTT styling, positioning metadata, and badly corrupted timing may still need manual repair.
FAQ
Subtitle Cleaner questions
What subtitle problems can this cleaner fix?
It helps with extra blank lines, trailing spaces, invisible characters, and simple SRT/VTT normalization.
Can it repair every broken subtitle file?
No. Severe timing corruption or missing timestamps still needs manual review.
Should I clean subtitles before AI translation?
Yes. Cleaner structure makes it easier for AI tools to preserve timestamps and return valid subtitle files.
