Generates translated subtitles from any video URL in one call
Generates translated subtitles from any video URL in one call. Composite: one call runs video-to-subtitles + translate. SRT subtitles are generated via Whisper v3, then the subtitle text is translated into the target language (100+ languages, structure preserved). Returns original subtitles, translated subtitles, and per-component telemetry. Use it for localized video captions, an SRT generator plus translation, or subtitle localization.
