How to translate one video into multiple languages

Caption your video once, then translate the subtitles and export a separate localized cut for every market — same timing, same look, in whatever language your audience speaks. On your iPhone, three videos a day free.

The short version: caption your video once in Just Captions, then run AI Auto Translate to convert the finished subtitles into another language while keeping the original timing. Review the wording, export a burned-in MP4 for that language, then switch the target and export again. One shoot becomes a Spanish cut, a Portuguese cut, a French cut — as many markets as you post to.

Step by step

One video, a cut for every language

  1. Caption the videoAdd your clip and let Just Captions transcribe the speech on your device and time clean subtitles to every word in the original language.
  2. Run AI Auto TranslatePick a target language and the app translates the finished captions for you — re-using the original timing so every line still lands on the right moment.
  3. Review the translationSkim the translated lines, fix any name, brand or idiom, and check that longer phrases still read comfortably in one or two lines.
  4. Export & repeatExport a burned-in MP4 for that language, then change the target language and export again to build a localized cut for each market you post to.

Tip: post each localized cut natively in-market rather than stacking languages on one video — viewers get captions in their own language from the first second.

Caption once, translate the rest

  • One transcription powers every language
  • Timing is re-used, so cuts stay in sync
  • A native-language cut per market beats one mixed video
  • Same styling keeps your brand consistent

Re-doing each language by hand

  • Re-typing and re-timing subtitles every time
  • Easy for lines to drift out of sync
  • Copy-pasting into a separate translator
  • Hours of work for a handful of markets
FAQ

Translating captions, answered

How many languages can captions be translated into?
Just Captions works across supported languages listed in the app, so you can translate one video's subtitles into a range of target languages and export a separate localized cut for each.
Do I have to re-caption the video for each language?
No. You caption the video once, then translate the finished subtitles. AI Auto Translate keeps the original timing, so each language version stays in sync without redoing the transcription.
Will the translated captions stay in time with the speech?
Yes. Translation re-uses the timing from the original captions, so each line appears at the same moment — you only review the wording.
Is translating captions free and private?
AI translation sends caption text for online processing and needs internet. Optional cloud recognition separately sends audio; use on-device recognition to keep transcription local. Usage allowances are shown in the app.
