Japanese → Chinese (Simplified)
To translate Japanese subtitles to Chinese (Simplified), upload your .srt or .vtt file to SubLingo, set the target language to Chinese (Simplified), and download the file with every timecode preserved. Chinese (Simplified) collapses to far fewer characters than Japanese (roughly 10% shorter on a character basis) but each glyph is full-width, so lines stay capped at 16 characters. Simplified Chinese uses full-width characters with no inter-word spaces, so Netflix caps lines at 16 characters and 9 cps. Keep each line under 16 characters and a reading speed below 9 characters per second — the limit Netflix sets for Chinese (Simplified) subtitles — and save the file as UTF-8 so every character survives the round trip.

Translating from Japanese into Chinese (Simplified): Chinese (Simplified) collapses to far fewer characters than Japanese (roughly 10% shorter on a character basis) but each glyph is full-width, so lines stay capped at 16 characters. Simplified Chinese uses full-width characters with no inter-word spaces, so Netflix caps lines at 16 characters and 9 cps. Because SubLingo rewrites only the text inside each cue, every timecode from the original Japanese file carries over to the Chinese (Simplified) version unchanged.
