Reaching a global audience used to require a budget for professional translators. With Capllio's Subtitle Translator, you can transcribe and translate your video subtitles into any of 99 languages in a single step — completely free.
How the translator works
When you upload your video to the Subtitle Translator, it first transcribes your audio, then passes the timestamped segments to a language model for translation. The output is a fully-translated SRT file with original timestamps preserved — ready to upload anywhere.
Which languages are supported?
99 languages are available for transcription. Translation supports any language the model understands — including Spanish, French, German, Portuguese, Hindi, Arabic, Japanese, Chinese, Korean, Italian, Dutch, Polish, Russian, Turkish, and many more.
Step-by-step: Translate your video subtitles
- Go to Capllio's Subtitle Translator
- Select your source language (or use Auto-detect)
- Select your target language from the "To:" dropdown
- Upload your video file (MP4, MOV, AVI, MKV, WEBM — no size or length limits)
- Wait 30–90 seconds for transcription + translation
- Click "Download SRT" to get your translated subtitle file
Tips for best translation quality
Select your source language manually rather than relying on Auto-detect when you know the language — it improves transcription accuracy which in turn improves translation quality. Clear audio is essential: background noise and overlapping speech reduce accuracy significantly. Review technical terms in the translated SRT before uploading — proper nouns, brand names, and technical vocabulary occasionally need manual correction.
For creators producing educational content, product demos, or tutorials, translated subtitles can multiply your addressable audience without any additional production cost.
