First video free, no card

Vidu Q4 free online: the box above runs Vidu Q4 in your browser, and a new account's 180 free credits cover a 5-second Vidu Q4 clip at 720p, with or without sound, with no card and no watermark. Add 1 to 10 photos of a product, a person or a pet, write what happens and press Generate.

A saved subject in RefVid: three photos of AERO 1, an invented running shoe, and a clip made from them in RefVid on Kling 3.0 Omni (the shoe rotates on a white plinth). The same saved photos go to Vidu Q4 when you start from the box above.

How to use Vidu Q4 free

  • Sign in with Google or an email code; no card is asked for. The account gets 180 free credits, and a 5-second Vidu Q4 clip at 720p costs less than that, with sound at the same price, so your first Vidu Q4 clip is free. In some regions new accounts get a free clip on Vidu Q2 instead.
  • The studio shows what a clip costs before anything runs. A longer clip or 1080p costs more than the free credits; the box says so and offers what fits. RefVid never adds a watermark.

Make a Vidu Q4 video online in 3 steps

  • 1. Add 1 to 10 photos of your product or character in the box at the top of this page. It is already set to Vidu Q4, and the photos are saved as one subject for the next clip.
  • 2. Write what should happen in a sentence or two. Settings changes the length (3 to 16 seconds), the shape (16:9, 9:16 or 1:1), 1080p and sound.
  • 3. Press Generate. If you are not signed in, you sign in first and the clip starts right after. A clip usually takes 2 to 10 minutes, and we email you when it is ready.

What Vidu Q4 is

  • Vidu Q4 is the newest video model from Vidu, listed on Vidu's API as Vidu Q4 Preview on October 7, 2026. Vidu's API takes up to 15 reference images and fal.ai's endpoint up to 12; it makes 3 to 16 seconds and can generate sound with the clip.
  • RefVid runs it through fal.ai as a reference-to-video model: you add up to 10 photos of one subject, and the next clip starts from the same photos.

After the free clip

  • Every clip is priced in credits per second. A single video costs from $2.99, a one-time credit pack from $9.90 and a monthly plan from $10; credits never expire, and a failed clip gives its credits back automatically.
