Captions + speaker ID FAQs

Are speaker tags written to the caption file?+

Yes. SRT uses [Speaker A] prefixes, VTT uses <v Speaker A>, ASS uses the Name field. No post-processing needed.

Can I rename speakers before export?+

Yes. Rename once and the new label flows into every caption line.

Will captions work for talk-show panels?+

Yes. Up to ten speakers is the supported range, plenty for typical panels and round-tables.

What if two speakers overlap?+

Overlap is detected and the dominant speaker per slice is tagged. Heavy crosstalk degrades like any system, but typical interviews stay clean.
