AI video localization — subtitles, dubbing, and captions.
Translate subtitles and captions with AI, validate timing, generate dubbing scripts, and export render-ready deliverables for every market — all in one connected workflow.
Every video localization workflow covered.
AI translates subtitle tracks into every target language while preserving the original SRT / VTT structure.
Generate accessibility-ready captions (SDH) for each locale, transcribed and translated from the original audio.
Automated checks flag subtitle segments where the translated text exceeds the display window — before it reaches post-production.
Generate lip-sync-adapted dubbing scripts for each language, ready to hand off to voice talent or TTS systems.
Route translated subtitles and scripts through native-speaker reviewers with inline editing and approval gates.
Export SRT, VTT, or burned-in subtitle deliverables. Download per locale or push to storage automatically.
Built for production video pipelines.
Frequently asked questions.
- What is video localization?
- Video localization is the process of adapting video content for different language markets. It includes subtitle translation, caption creation, dubbing script generation, timing QA, and producing render-ready deliverables per locale.
- What is the difference between subtitles, captions, and dubbing?
- Subtitles translate spoken dialogue into text for viewers who speak another language. Captions (SDH) transcribe spoken audio including sound effects for viewers who are deaf or hard of hearing. Dubbing replaces the original audio track with a recorded voice performance in the target language.
- How does AI dubbing work?
- AI dubbing starts with transcribing the source video, translating the transcript for each target language, adapting the script to match speaking pace and lip-sync timing, and then producing a script ready for voice talent or TTS synthesis.
- What subtitle formats does Humlens export?
- Humlens exports SRT (SubRip Text) and VTT (WebVTT) subtitle files — the two most widely supported formats across video platforms, streaming services, and social media.
- Can I localize videos in batch for multiple languages at once?
- Yes. Humlens can translate a subtitle track into multiple target languages simultaneously. You configure your target languages, run the translation, and export per-language subtitle files in one workflow.
- How do I localize a video for social media (Instagram, TikTok, LinkedIn)?
- Upload your video to Humlens, translate the subtitle track for each target market, export SRT or VTT files, and burn them into the video or upload as a separate track depending on what each platform supports.
