Permanent FL subtitle FAQs

Which language pairs are supported?+

Any pair across the 99-language set — Chinese↔English, Japanese↔English, Korean↔English, Turkish↔Spanish, and many more.

Are translation captions style-consistent across speakers?+

Yes. Each speaker keeps an assigned colour, and the FL caption renders inherit it.

Is the burn truly permanent?+

Yes. The captions are part of the picture frame. No platform can strip them out.

Can I review the translation before injection?+

Yes. The translated transcript opens in the Studio for inline edits; injection happens on Export.
