Burned-in subtitles · OCR + translation

Translate hardcoded subtitles from Chinese, Korean and Japanese videos

Auto-caption tools listen to the audio, so they cannot help when the subtitles are part of the picture. SubtitleVideo reads the burned-in text frame by frame, gives it back as a timed SRT file and translates it to English or 80+ other languages.

How to translate burned-in subtitles

Three steps, no software to install.

1

Upload the video

MP4, MKV, MOV, WebM and other formats. Long episodes and full movies are fine.

2

Pick the two languages

The language of the burned-in text (for example Chinese) and the language you want (for example English). Keep “Subtitles only” to skip logos and watermarks.

3

Download the subtitles

Get the original and the translated subtitles as SRT or VTT, with the original timing. Fix lines in the Subtitle Studio if you want.

Tips for the best result

Use the best copy you have

OCR reads pixels. A 720p or 1080p file gives clearly better text than a small re-compressed copy, especially for Chinese and Japanese characters with many strokes.

Two lines of subtitles in two languages?

Choose the language you want to read as the source language. If the video already shows English under the Chinese line, you can extract the English line directly instead of translating.

Check names and slang

Machine translation is good at everyday dialogue, less so at names, puns and slang. Open the result in the Subtitle Studio to fix a few lines before you publish, or ask us for a human-checked translation.

Questions about translating burned-in subtitles

Which languages can it read in the picture?

Chinese (simplified and traditional), Japanese, Korean, English, Vietnamese, Thai, Arabic, Russian, Spanish and most other written languages. Choose the language of the burned-in text when you upload: it helps the text recognition.

Which languages can it translate to?

English and 80+ other languages. Pick the translation language in the same form. You can also translate the SRT file later, for free, with the Subtitle Translator.

Do I get the original subtitles too?

Yes. You get the subtitles in the original language with their timing, and the translated version, both as SRT or VTT.

Can I remove the old Chinese subtitles from the picture?

Yes, with the Subtitle Remover: draw a box over the subtitle area and download a clean video, then add your translated subtitles on top.

How accurate is it?

On clear subtitles in a 720p or better video, most lines come out right. Blurry, very small or stylised text, and text over busy backgrounds, gives more mistakes. Try a short clip with the free minutes first.

How much does it cost?

Reading burned-in text uses 2 minutes of credit per minute of video, about $0.25 per video minute. You pay once for credit, there is no subscription.

I need a perfect translation for a release. Can a person check it?

Yes. Our human-reviewed service fixes the recognised text and the translation by hand. Request a quote with a sample clip.
