AI video generator

Describe a scene in one sentence and get a video of it. Attach a portrait of a person, and that same face stays on screen from the first frame to the last.

Made with this tool, from a portrait the AI image tool drew.

From a sentence to a clip

Write what should happen: who is in the shot, what they do and where. You can write in Vietnamese or English; a Vietnamese description is translated before the video is made, and the one you typed is what your library shows.

Keep one face from start to end

The hard part of AI video is that people drift: a few seconds in, the face is someone else's. Attach a portrait and the clip is held to that face the whole way through.

No portrait yet? Make one with the AI portrait generator, then press "Make a video from this image" under the result. It opens AI video with that portrait already attached.

Length and price

Choose anything from 5 to 60 seconds. Clips are made in 5-second steps, and you pay for the length you get, at 6 credits a second:

ClipCredits
5 seconds30
10 seconds60
30 seconds180
60 seconds360

The exact price is on the button before you create. If a render fails, the credits go back to your account automatically. AI video needs a free account; new accounts start with 10 free credits, and more are a one-time purchase by Vietnamese bank transfer or crypto that never expires.

While it renders

A clip takes about 10 to 25 minutes to make. You do not have to wait on the page: close it, and the finished video will be in your library. It stays there for 12 hours, so download the one you want to keep.

Only put a person in a video if you have the right to use their face — your own, or someone who agreed. Impersonating people is not allowed, and accounts used that way are closed.

How much does it cost?

6 credits a second: 30 credits for 5 seconds, 360 for a full minute. If a render fails, the credits come back automatically.

Yes. Attach a portrait and that face stays from the first frame to the last. No portrait yet? Make one with the AI image tool and press "Make a video from this image".

How long does it take?

About 10 to 25 minutes. You do not have to wait on the page: the finished clip lands in your library, where it stays for 12 hours.
