“For a cooking course that runs several hours, subtitles aren't enough. Our standard is that every viewer gets the same experience, no matter which language they learn in. That's exactly what Dubly.AI makes possible for us, without cutting any corners on quality.”

Less production time per course
Whether a translation feels real is decided in the moments where things usually slip: a hand in front of the mouth, a turn of the head, two people in frame. That is exactly where we work — so your audience watches the video, not the technology behind it.
Most models break the moment a hand, a microphone or a phone covers the face. Ours doesn't: it reads what is hidden and carries the lip movement on behind it — no jumps, no artefacts. This is where the world's leading model separates itself from the rest.

Lip sync refers to the adjustment of a speaker's mouth movements to match the translated language.
Thanks to advanced AI technology, the video looks as if the speaker actually delivered the translated version themselves.
Facial expressions and natural movements are preserved from the original, ensuring a highly authentic result.
For the best lip sync results, make sure the speaker's face, especially the mouth, is clearly visible and well-lit. Avoid shadows, backlighting, or anything covering the face like hands, microphones, or subtitles. The speaker should talk at a natural pace and ideally face the camera. Background noise or poor audio quality can also negatively impact the sync.
Lip sync costs 2 credits per minute instead of 1, so 100 credits cover 50 minutes with lip sync enabled. It stays optional — you enable it per video after the first step (standard translation).
No. None of the data you upload, whether video or audio, is used to train AI models.

Yes, Dubly.AI supports videos with music and background noise.
The platform's advanced technology can distinguish between the primary speech track and other audio elements like music or ambient sounds, enabling accurate speech synthesis and translation of spoken content.
For best results, we recommend using videos where the spoken voice is clearly distinguishable from background noise.
