Translate an SRT or WebVTT subtitle file into another language
Translate an SRT or WebVTT subtitle file into another language. Only the cue text is translated; every cue number, timing line and header is copied exactly, and the output is checked to parse back to the same cues and timings, or it is refused unpaid. Body { subtitles, to, from }: up to 50 KB. Workers AI (Llama 3.1 8B) translates the text, so check it before publishing. Not live-checked: the owner tests it on the Worker after the merge.
