SRT matrix FAQs

What variants does the matrix include?+

Master, per-speaker tracks, and translated variants for any of the 99 supported languages.

Are variants delivered as separate SRT files?+

Yes. The export bundles them as a zip with a manifest describing each track.

Can I add a translation variant after the fact?+

Yes — translations are generated on demand from the master transcript.

Will speaker IDs be consistent across variants?+

Yes. Renaming a speaker updates them across every variant in the matrix.
