01 — How it works
How to use Vidu Q4
One photo, one prompt
01
Upload a photo
Your photo becomes the first frame. The video keeps its aspect ratio, so portraits stay portrait and landscapes stay wide.
02
Describe the motion
Say what happens and how the camera moves — "she turns, smiles and tucks her hair behind her ear, slow push in".
03
Pick resolution, length and audio
540p, 720p, 1080p, 2K or 4K; any length from 3 to 16 seconds; audio on or off at the same price.
04
Generate and download
Your MP4 is saved to your library as soon as it is ready.
02 — Features
Vidu Q4 features
Five resolutions up to 4K
Test ideas at 540p for 18 credits a second, then render the keeper in 1080p, 2K or 4K.
Native audio
Dialogue, ambience and sound effects are generated together with the picture. Switch audio off for a silent clip — the price is the same.
3 to 16 seconds
Choose any whole-second length, so short tests stay cheap and longer shots need no stitching.

Vidu Q4 FAQ
How much does Vidu Q4 cost?
18 credits per second at 540p, 38 at 720p, 48 at 1080p, 76 at 2K and 156 at 4K, with or without audio. A 5-second 720p clip costs 190 credits. Every account gets 20 free credits a month, and credit packs start at $9.90 for 600 credits.
Can Vidu Q4 make a video from text only?
No. Vidu Q4 always starts from a photo, which becomes the first frame. For prompt-only videos, try Seedance 2.5 or Wan 3.0.
What aspect ratio do I get?
The video follows your photo's aspect ratio — upload a vertical photo for 9:16 or a wide one for 16:9.
Can I upload a video or a voice sample as a reference?
No. Viberot only accepts a photo and a prompt for Vidu Q4 — uploading your own video or voice recordings is not supported, to prevent face swapping and voice cloning of real people.
What if the generation fails?
Failed generations are refunded automatically, so you only pay for videos you receive.
Who can see my videos?
Your uploads are only used for your generation. Free-account videos appear in the public gallery; subscribers can keep them private.
