Length and layout
English is about 15–25% shorter than the Spanish original. Both languages are written left to right, so the layout does not change — only the wording and line length do.

Translate Spanish video into English subtitles
Upload a video in Spanish. SubFlow transcribes the speech, translates every caption into English, and keeps both languages on the same timeline so you can review them side by side — then export subtitles, a subtitled video, or a English dub.

Getting English right
English subtitles read fastest when a line breaks after a clause, not mid-phrase — the editor lets you move the break without touching the timing.
Workflow
From Spanish to English in three steps.
Upload the Spanish video
Add a video or audio file. SubFlow transcribes the Spanish speech into timed captions.
Translate into English
Pick English as the target. Every caption is translated with the surrounding lines as context, then shown beside the original.
Review and export
Fix names and terms, split any caption that runs long, then export English or bilingual subtitles, a subtitled video, or a English dub.
Common questions
Spanish to English, answered.
Can SubFlow recognise Spanish speech automatically?
Yes. Leave the source on automatic detection or pick Spanish yourself. Latin American and European Spanish are both transcribed accurately; the spelling follows what was said.
Will the English subtitles fit on screen?
English reads comfortably at 15–17 characters per second with about 42 characters per line. English is about 15–25% shorter than the Spanish original. Review the longest captions and split any that crowd two lines.
Can I dub a Spanish video into English?
Yes, on the Pro plan. The English dub uses a en-US voice and is spoken from the translated subtitles, so correcting a line in the editor changes what the voice says.
Can I export Spanish and English together?
Yes. Export the English subtitles alone, the original Spanish, or a bilingual SRT with both on each caption — or burn either into the video.
