Vidu Q4: ShengShu's 4K AI video model, explained

Vidu Q4 is the next flagship video model from ShengShu Technology, the company behind Vidu AI. The Preview went live on 7 October 2026 with 4K output, native sound and a heavy focus on believable acting: expressions, emotion and voice that move together. It only does image-to-video and reference-to-video for now. Here is what that means for a TikTok, Reels and Shorts calendar.

What Vidu Q4 is

Vidu Q4 is ShengShu Technology's next-generation flagship AI video model, released as Vidu Q4 Preview on 7 October 2026: it turns one image, or up to 15 reference images plus up to 3 voice clips, into a clip of up to 16 seconds with synchronized speech and sound effects, at up to 4K with 10-bit color, from $0.014 per second at launch pricing. It is available in Vidu's web product and API.

For marketers the point is performance: Q4 is built to keep a character's face, emotion, body movement and voice in sync, which is what makes AI UGC style clips read as human.

What changed in Vidu Q4

Vidu Q3 Pro, announced on 30 January 2026, was the first Vidu model to generate up to 16 seconds of 1080p video with native dialogue, sound effects and music in one pass. Q4 Preview keeps the 16 second ceiling and native audio, and adds 4K and 2K output, 10-bit color, up to 15 image references and 3 voice references, and a stronger focus on acting: facial expression, emotion, body movement and voice in sync.

How to get Vidu Q4

The Vidu web app and the Vidu API platform. Launch pricing starts at $0.014 per second; the Preview label means specs and pricing may change before the full Q4 release.

What Vidu Q4 means for short-form marketers

Most AI video models are judged on cinematic shots. Short-form is judged on faces: a creator talking to camera, a reaction, a product held up with a line delivered over it. Q4 is explicitly tuned for that, coordinating expression, emotion, movement and voice, and the 3 voice references mean you can keep the same voice across a whole series rather than rolling a new one each time.

The missing text-to-video mode is less of a limit than it sounds for brands. You almost always start from a real product shot or an approved character image anyway, and reference-to-video with up to 15 images is exactly how you keep packaging, logos and a recurring character consistent across a week of posts.

Treat 4K as a nice-to-have: TikTok, Reels and Shorts compress hard, and 1080p is plenty for vertical feeds. The real decision is cost per usable clip, so test at 720p or 1080p before budgeting at 4K.

Where Vidu Q4 still needs care

  • Preview release: specs and pricing may change before the full Q4 launch
  • No text-to-video; every generation needs at least one image
  • Up to 16 seconds per generation, so full ads still need stitching and captions
  • The $0.014 per second launch price applies at the lowest resolution; higher resolutions cost more
  • Plan to disclose AI-generated content on TikTok and Instagram as usual
