About Vidu AI
What Is Vidu AI
Vidu AI is a video generation tool built by Shengshu Technology, a Beijing company spun out of Tsinghua University research. It takes a written prompt, a still image, or a set of reference materials and returns a short animated clip. The pitch is speed and control: the team has pushed generation times into seconds and made character consistency the centerpiece of the product.
Its signature feature is reference-to-video, which the company introduced before competitors like Sora shipped comparable cameo tools. Instead of describing a character in words and hoping the model keeps it stable, users upload a photo of a person, a product, or a mascot, and Vidu holds that subject steady across shots and scenes. For anyone making short dramas, ads, or animated shorts, that removes a chunk of the tedious re-generation work that older tools demanded.
The scope has limits. Clips are short by design, and length is tied to the plan, so long-form storytelling still leans on the video extension feature rather than a single pass. Quality varies with prompt detail, and the heaviest professional controls sit behind paid tiers. It's also a China-based platform, which matters for teams with data residency or procurement rules.
Getting Started
- Sign up at vidu.com with an email or third-party account, which lands a small bundle of free credits.
- Pick a mode: text to video, image to video, or reference to video.

Key features
Reference to video with multi-subject consistency
This is the feature Vidu built its name on. Users upload images of people, objects, or places, then describe what should happen, and the model keeps each subject recognizable as the camera moves. The company pushed the limit to several simultaneous references, which covers the cast, wardrobe, and set of a short scene. In practice it means a character who appears in shot one looks like the same character in shot five, a problem that older image-to-video tools handled poorly.
Text to video and image to video
For simpler jobs, Vidu works like most AI video generators. A text prompt alone can produce a clip, and a single image can be animated into motion. Output supports common aspect ratios and resolutions, so the same prompt can feed a vertical social clip or a wider shot.
Cinematic camera control
The model understands common camera language such as push, pull, pan, and tracking shots, so a prompt can ask for a specific move rather than leaving framing to chance. This is aimed at creators who think in shots and want the generator to follow their intent instead of improvising.
Video extension
Short clips are the norm for AI video, and Vidu counters that with an extension feature that stretches a generation toward longer runtimes. It keeps the subject and look consistent as the clip grows, which makes it possible to build a scene from a short seed rather than trying to force everything into one pass.
Fast generation and peak-hour mode
Speed is a stated part of the value: the team has pushed inference into the seconds. The platform also runs an off-peak mode where generation during quiet hours isn't counted against credits, which gives heavy users a way to keep working without burning through a plan.
Image generation and a creation-to-distribution app
Alongside video, Vidu offers text-to-image and reference-to-image, with high-resolution output. The companion app reframes the tool as a place to create and share, not just render, so finished clips can be posted and interacted with inside the same product.
Pros and cons
Pros
- Reference-to-video delivers character and product consistency, which is the hardest part of AI video to get right.
- Generation is fast, with inference times measured in seconds on lighter models.
- The free tier gives new users enough credits to test real prompts before paying.
- An open API lets developers embed video generation into their own products.
- Off-peak mode and a low per-second cost make high-volume work more affordable.
Cons
- Clip length is capped by plan, so long narratives depend on the extension feature.
- Professional controls like higher frame rates and resolution sit behind paid tiers.
- Output quality tracks prompt skill, and weak prompts produce weak clips.
- Watermarks and shorter expiry on free-tier output limit commercial use.
- It's a China-based service, which can complicate procurement for some organizations.
