FAQ

Frequently asked questions

How long does dubbing take?

Most videos under 10 minutes are processed within 15-30 minutes. Longer videos or those requiring lip sync may take up to a few hours.

Is my video data private?

Yes. LinguaDub runs on private infrastructure — not shared cloud APIs. Your videos are processed on dedicated servers and deleted after delivery. We never use your content for training.

What about copyrighted content?

You must have rights to dub the content you upload. We do not process content that violates copyright. Personal-use dubbing of content you own (like family videos) is fine.

How is this cheaper than competitors?

We run our own GPU infrastructure instead of paying per-minute API costs to cloud providers like ElevenLabs or Google. Our marginal cost per dub is near zero, so we pass the savings to you.

What video formats are supported?

Any format FFmpeg can read: MP4, MKV, AVI, MOV, WebM, and more. Output is always MP4 with H.264 video and AAC audio.

Can I dub into multiple languages at once?

Yes. With Pro and Premium plans, you can dub a single video into multiple languages in one batch. Each language gets its own output file.
