Frequently asked questions

What changes when SRT is converted to VTT?

The converter adds the WEBVTT header and changes timestamp milliseconds from a comma to a period while preserving cue timing and text.

Does SceneDub upload my SRT file?

No. This converter reads and transforms the subtitle text locally in your browser.

Can I download the converted VTT file?

Yes. You can copy the generated WebVTT text or download it as a .vtt file.

Will subtitle styling be preserved?

Basic cue text is preserved. Format-specific positioning, comments, regions, and advanced styling should be reviewed after conversion.
