Vidu Q4 Preview hands-on: flagship video model from ¥0.09/second
Shengshu Technology has opened preview access to Vidu Q4 Preview, a next-generation video generation model it positions as a "high-expressiveness flagship" focused on character acting, camera work and complex VFX, starting at ¥0.09 per second. In a hands-on test, ifanr found the model strong on camera direction, subject stability and effects that interact with the scene, with support for up to 15 reference images, three reference audio clips and optional 2K/4K output, but weaker on pacing during sharp emotional turns, style control and the hallucination issues common to AI video. The company says the preview is meant to gather real-world feedback before a full release.
Video model competition is shifting from raw image quality toward acting and narrative camera work, while low per-second pricing makes repeated takes affordable for creators.
