Portuguese → French
To translate Portuguese subtitles to French, upload your .srt or .vtt file to SubLingo, set the target language to French, and download the file with every timecode preserved. French and Portuguese land at similar line lengths (within a few percent), so existing line breaks usually still fit. French elides words with apostrophes (l', d', qu') and uses accents (é è ê ç) plus guillemets « » for quotes. Keep each line under 42 characters and a reading speed below 17 characters per second — the limit Netflix sets for French subtitles — and save the file as UTF-8 so every character survives the round trip.

Translating from Portuguese into French: French and Portuguese land at similar line lengths (within a few percent), so existing line breaks usually still fit. French elides words with apostrophes (l', d', qu') and uses accents (é è ê ç) plus guillemets « » for quotes. Because SubLingo rewrites only the text inside each cue, every timecode from the original Portuguese file carries over to the French version unchanged.
