Questions

Frequently asked questions

Does this translate subtitles into Hindi?

No. It only cleans and normalizes Hindi text that already exists.

Can it recover characters already shown as boxes?

Not reliably. Boxes can come from a missing font or permanently damaged source bytes.

Will timestamps be preserved?

Yes. The normalization operates on the full pasted subtitle text and does not rewrite valid timestamps.
