How to translate video captions and subtitles.

Transcribe the original speech, translate the text, then review timing, line breaks, and terminology before you publish the new language.

Translating subtitles to another language used to be a freelancer-only workflow. AI translation has closed the gap on simple, conversational content — but it still fails on idioms, technical jargon, and culturally-specific references. The 2026 best practice is a hybrid: AI for the first pass, human review for everything that ships to a real audience.

Step by step

  1. 01
    Export your source SRT
    From SoCaptions, export the SRT in your original language. SRT is the most-supported format for translation tools and human translators.
  2. 02
    AI translation for first pass
    Use a translation tool for the first pass, then review names, idioms, technical terms, and culturally specific references before publishing.
  3. 03
    Human review for anything public
    Hire a native speaker to review the AI output, especially for proper nouns, idioms, and culturally-specific references. Cost: $0.50–$2.00 per minute of video runtime.
  4. 04
    Upload the translated SRT separately
    Don't replace your original SRT. Add the translated SRT as a separate language track. YouTube, Vimeo, and most platforms support multiple language tracks per video.
Pros
  • AI can produce a fast first pass
  • Translated SRTs feed each language's search index independently
  • Multiple language tracks expand reach when audience demand is validated
  • First-pass cost is near-zero for AI translation
Cons
  • AI fails on idioms, jargon, and culturally-specific references
  • Mistranslations damage brand more than missing translations
  • Some languages (e.g., low-resource African languages) have weak AI quality
  • Right-to-left languages (Arabic, Hebrew) need direction-aware rendering

FAQ

What's the best AI for translating SRT files?+

DeepL is best for European languages. Google Translate is broadest. Claude / GPT-4 are best for nuanced content. Always human-review before publishing.

Should I auto-translate my YouTube SRT into 10 languages?+

Probably not. Pick your top 1–3 audience markets, translate well, and ship. Bad translations to 10 markets hurts your brand more than no translations.

How long does subtitle translation take?+

AI: 30 seconds per SRT. Human review: 30–90 minutes per 10 minutes of video. Full human translation: 4–8 hours per hour of video.

Can I burn translated subtitles into the same video as the original?+

Technically yes, but it crowds the frame. Better: render separate MP4s (one per language) or use soft captions with multiple language tracks.

Can I translate a VTT file?+

Yes. Keep the WEBVTT header, cue timestamps, and cue settings intact while translating only the caption text. Review line length and timing in the target language before publishing.

How to hardcode subtitles into a video

Hardcoding subtitles is the same as burning them in — captions become part of the video pixels permanently. Same trade-offs, same techniques. 'Open captions' is the broadcast term for the same thing.

Sync subtitles with video

Out-of-sync subtitles come from one of three causes: a fixed offset, a frame-rate mismatch, or progressive drift. Each has a different 5-minute fix.
