Webinar translation & subtitles
Webinar translation with the speed of AI and a translator's eyes and ears.

Double screening
AI transcribes. A translator checks twice, by eye and by ear.
AI transcription is fast, but it leaves errors in technical terms, names and who said what. We treat AI output as a draft only, and a translator checks it in two passes.
STEP 1 · AI
AI transcribes the audio
AI turns the webinar audio into text and splits it by speaker — quickly, even for long recordings.
STEP 2 · Translator's eyes
Read-through check
The translator reads every line of the transcript and translation against your slides and handouts, fixing speaker names, company and product names, terms and numbers.
STEP 3 · Translator's ears
Listening check
The translator listens from start to finish to fix mishearings, mixed-up speakers and errors caused by hesitations — and checks subtitle timing along the way.
STEP 4 · Delivery
Subtitle files delivered
You receive SRT/VTT subtitle files. We can also export a version with burned-in subtitles.
Neither AI alone nor manual work alone. AI handles the speed of transcription; a translator guarantees accuracy with both eyes and ears. Even long webinars come back fast, affordable and right.
Why webinars are hard
Where automatic webinar translation goes wrong
Webinars combine everything that trips up AI transcription and machine translation. Our double screening focuses on four areas.
Technical terms and product names
AI tends to replace industry jargon and product names with common words. The translator checks them against your materials.
Multiple speakers and Q&A
Panels and Q&A sessions switch speakers constantly. Attributing a line to the wrong person changes its meaning.
Numbers and names
A misheard revenue figure, date, percentage or name becomes a credibility problem. The listening check verifies each one.
Audio quality and spoken language
Poor microphones, hesitations and restarts are where AI transcripts break down. A person listens and restores the intended meaning.
What you can do
Turn recorded webinars into content for a new audience

Export a subtitled video
For platforms without caption support and social clips, we export a version with burned-in subtitles, including vertical formats.
Add dubbed audio
Add a dubbed audio track built from the approved subtitle translation, so terms match between subtitles and voice.

FAQ
Webinar translation FAQ
Isn't AI transcription or machine translation enough?
For webinars, often not. Errors in technical terms, product names, speaker names and numbers — and mixed-up speakers in Q&A — tend to remain. We use the AI transcript as a draft, and a translator fixes errors through a double check by eye and by ear before delivery.
What exactly does the double screening check?
In the read-through, the translator reads every line of the transcript and translation against your slides and materials to verify names, terms and numbers. In the listening check, they listen from start to finish to catch mishearings, mixed-up speakers and subtitle timing.
Should I share the slides or handouts?
It is not required, but it improves accuracy, because we can confirm speaker names, product names and technical terms against them. Please also send preferred spellings of your company name and titles, or any existing glossary.
How much does it cost and how long does it take?
Subtitles are JPY 1,200 per video minute, so a 60-minute webinar is JPY 72,000 (excluding tax), delivered in 2–4 business days. Dubbing is JPY 2,800 per video minute and the bundle is JPY 3,500 (excluding tax).
Can you handle a webinar series?
Yes. We build a glossary on the first session and carry it over, so terms become more consistent with every episode. Single videos, orders of 10+ and monthly retainers are all welcome.
How do I send the recording?
Either a video file or a link is fine. Enter a YouTube, Vimeo or Google Drive link in the form, or if you would rather send the file, we will reply with how to share it.
