Quick answer
Vidu, from Shengshu Technology, is one of several Chinese AI video generators — alongside Kling, Hailuo, and Seedance — closing the quality gap with Western leaders like Sora and Veo.
When Kling from Kuaishou first turned heads with realistic AI video, it looked like an outlier. It wasn't. Vidu, Hailuo, Seedance, and a handful of other Chinese video models have kept shipping fast, and the gap with OpenAI's Sora and Google's Veo has kept shrinking.
What is Vidu, specifically?
Vidu comes from Shengshu Technology, working with researchers connected to Tsinghua University, and has iterated through multiple versions since its initial release. Like its competitors, it turns text or image prompts into short video clips, with each new version pushing longer duration, better physical consistency, and more controllable camera motion.
- Text-to-video and image-to-video generation with increasingly coherent motion between frames.
- Reference-image features letting users keep a consistent character or subject across multiple generated clips.
- Rapid version cycles — Chinese video labs have generally shipped updates faster than their Western counterparts.
How does the Chinese AI video field compare to Sora and Veo?
Direct, apples-to-apples comparisons are hard because every lab benchmarks against its own cherry-picked demos. That said, a few honest patterns hold up.
- Chinese models have closed much of the visual-quality gap that existed even a year earlier, and in some narrow categories — like anime-adjacent or stylized content — some arguably lead.
- Sora and Veo still tend to have an edge on physical realism and following complex, multi-step prompts precisely, though the margin keeps narrowing with each release cycle.
- Pricing and iteration speed favor the Chinese labs, who tend to ship cheaper consumer apps and update them more frequently.
Why is China moving so fast in this specific category?
Several forces compound here: a huge domestic short-video culture already trained users and investors to want this exact product, intense competition among ByteDance, Kuaishou, Alibaba, and others pushing rapid iteration, and a willingness to ship fast and improve in public rather than wait for a fully polished release.
Global reach is where things diverge from raw model quality. Distribution for these apps outside China is uneven — app store availability, payment processing, and geopolitical scrutiny all complicate how easily an average user outside China can actually try them, regardless of how good the underlying model is.
Does content moderation differ between Chinese and Western video models?
Yes, in both directions. Chinese platforms typically have stricter controls around domestic political content and censorship-sensitive topics, while some have historically been comparatively looser on certain likeness or stylistic content that Western platforms restrict more tightly for legal and reputational reasons. Neither side is "unmoderated" — the restrictions just point at different things.

Bottom line
Vidu isn't a one-off — it's another data point in a real trend: the Chinese AI video field is no longer playing catch-up on quality alone, it's competing on speed and price too. The Sora-versus-Veo framing misses half the actual race.
