Use cases
One upload. Very different videos.
A dub has to fit the video it is for. An ad needs lips that match; a cartoon needs its character voices; a course needs every term right. Pick what you make and see what to expect.
Hear one
The same character, in the language you pick.
What every example on these pages shows
Play the clip and switch the language under it. The picture never changes: the speech is replaced, and the music and background sound stay.
Every clip on this site is an AI-generated scene, dubbed with the model the app runs. None of them is a customer video.
What is said: Hi, I'm Pip the Fox. My stories began in one language. Now, children can hear them in their own.
What is said: Hola, soy Pip el Zorro. Mis historias comenzaron en un idioma. Ahora los niños pueden escucharlas en el suyo.
What is said: Oi, eu sou Pip, a raposa. Minhas histórias começaram em um idioma. Agora as crianças podem ouvi-las no seu próprio.
Demo clip: an AI-generated scene with a fictional character. Dubbed with VDub v2, the model DubSync runs; lip-synced tracks use VSync v2.
By kind of video
What are you translating?
Animation needs its character voices and its music. A film needs every speaker to stay recognisable. A course needs the terms right. Each page starts with a clip of that kind, dubbed, and then says plainly where a dub works and where to take care.
