Turn Japanese video or audio into Chinese subtitles, exported as SRT, VTT or plain text with the original timings intact. Japanese is written without spaces, so word boundaries are decided during recognition and carry into the translation.
Where Japanese words begin and end
Japanese is written without spaces between words, so deciding where one word stops is part of recognition rather than something applied to the transcript afterwards. That matters more here than it would for a same-language transcript: the translation into Chinese runs on those segments, and a boundary in the wrong place changes what gets translated.
It is also why subtitle timings on Japanese audio are worth spot-checking at the start and end of each line, where segmentation decisions land.
How Japanese audio becomes Chinese subtitles
Audio in Japanese (日本語) is transcribed first, then translated into Chinese (中文). Because the translation runs on the transcript rather than on the audio, the Chinese subtitle file keeps the timings of the original Japanese speech — each line appears at the moment it was actually said.
From kanji and kana to Chinese characters
Japanese is written in a mix of kanji, hiragana and katakana and Chinese in Chinese characters, so the exported file uses a different writing system from the audio that produced it. The subtitle formats handle that — SRT and VTT are plain text and carry any script — but the font in whatever plays the file has to cover it.
This is the most common reason a Chinese subtitle track looks correct in an editor and shows boxes or blanks on a device. Test on the target platform before you publish a batch.
Why translate Japanese video into Chinese
Japanese is spoken principally in Japan; Chinese in mainland China, Taiwan, Singapore and Chinese-speaking communities worldwide. A Chinese subtitle track is what lets one recording reach both audiences without re-recording, re-editing or dubbing it.
Because subtitles are a separate file rather than part of the picture, you can attach several language tracks to the same video and let viewers pick.
About the Japanese audio
Japanese is written without spaces between words, so segmentation is part of recognition rather than something that happens afterwards — this is why word-level timings matter more here than in a space-separated language. Output mixes kanji, hiragana and katakana as normal written Japanese does.
About the Chinese subtitles
Like Japanese, Chinese is written without spaces, so word boundaries are inferred during recognition. Mandarin is what is transcribed; Cantonese is a separate option and choosing the wrong one produces fluent-looking output that does not match the audio.
What a Japanese to Chinese subtitle file looks like
Four lines of Japanese speech, transcribed and translated, as they come out of the exported SRT. The timings are the Japanese speaker's — translation does not move them, which is why the file drops onto the original video unchanged.
Almost always, but it depends on the font rather than the file — SRT and VTT are plain text and carry Chinese characters without difficulty. If you see empty boxes, the player is missing a font for the script, not reading the subtitles wrongly.
How do I add Chinese subtitles to a Japanese video?
Upload the video, set the spoken language to Japanese and the subtitle language to Chinese, then export the result as SRT and upload it alongside your video. Nothing is burned into the picture, so the subtitles stay switchable.
Does the Chinese subtitle file stay in sync?
Yes. Translation happens on the transcript, so every Chinese line inherits the timing of the Japanese words it came from. The file will sync with the same video without adjustment.
Can I get the Japanese transcript as well?
Yes. Transcribing Japanese into Japanese subtitles is a separate job on the same recording, and gives you the original-language track alongside the Chinese one.
