Translate Spanish Video to English: Subtitles or a Voice
Upload a Spanish video or paste a link, and BlaBlaScribe transcribes the Spanish, translates it into English and gives you English subtitles or an English dub with a voice for each speaker. English text is about 16% shorter than Spanish, so dubbed lines fit their slots and are slowed slightly rather than rushed.

Spanish to English vs English to Spanish
The same translation runs the other way round when the source is Spanish, and that changes what the dub has to do with each line.
| Spanish → English | English → Spanish | |
|---|---|---|
| Text length | About 16% shorter | About 19% longer |
| Time to say it | About 9% less | About 10% more |
| What the dub does | Lines usually fit; a line under 85% of its slot is slowed, never below 0.85× | Long lines are sped up by at most 1.2× and may take up to 1.5 seconds of the next pause |
| Lines you review | Few: mostly names and terms | More: flagged lines to shorten |
| Subtitles | Shorter English lines are easier to read at the original timing | Longer Spanish lines may need two lines on screen |

Getting a Clean English Version
Spanish to English is the easier direction for timing; the work moves to meaning.
Names
Fix names and places in the Spanish first
Recognition writes what it hears. Correct people, brands and places in the Spanish transcript, and the English repeats them correctly.
Idioms
Read the idioms
Expressions like echar una mano or ponerse las pilas need a meaning, not a word-for-word translation. Scan the English for lines that sound literal.
Speakers
Turn on speaker recognition
Interviews and panels need it: each speaker then gets a voice of their own and the subtitles can show who is talking.
Pace
Listen to the slow lines
English lines that come out much shorter are slowed slightly. If one sounds sleepy, add a word or two to the voice-over text.
