Vidu
AI video generation with character-consistent output — up to 16 seconds at 1080p HD
Vidu is an AI video generation platform by Shengshu Technology, a Beijing-based AI startup backed by major Chinese investors. It generates video clips from text prompts and reference images with a specific focus on character consistency — maintaining a subject’s visual identity reliably across frames. Clips run up to 16 seconds at 1080p resolution, and the reference-subject workflow makes Vidu particularly strong for portrait-driven and character-centric video content that requires the same person or character to appear throughout a generated sequence.
Visit ViduWhat is Vidu?
Vidu is an AI video generation platform developed by Shengshu Technology, a Chinese AI startup founded in 2023 with academic ties to Tsinghua University’s AI research community. The platform was built around a specific technical hypothesis: that the biggest unsolved problem in AI video generation was not clip length or visual quality per se, but the consistent rendering of specific characters and subjects across multiple frames. Vidu’s model was trained to address this directly, making it one of the most reliable tools available for generating videos featuring recognizable people or fictional characters.
The reference-subject workflow is the heart of Vidu’s product. You upload a reference photo of a person, character, or even a product, and then write a text prompt describing the action and setting you want to generate. Vidu generates a video in which the reference subject performs the described action while maintaining their visual appearance — face structure, skin tone, hair, and clothing — throughout the clip. This is meaningfully different from standard image-to-video generation, where the subject often drifts in appearance between frames. For creators who need consistent character representation, Vidu’s approach is a significant practical advantage.
Technically, Vidu supports video generation at 1080p resolution with clips up to 16 seconds long on paid plans — longer than Luma Dream Machine’s 9-second cap but shorter than Kling AI’s 2-minute maximum. The platform offers both quick generation modes (4 and 8 seconds) and extended generation for longer sequences. Multiple aspect ratios are supported, including 16:9 for cinematic landscape output, 9:16 for vertical social media content, and 1:1 for square format.
New users receive 80 free credits on account creation, which is enough to generate a handful of clips and genuinely evaluate the platform before committing to a subscription. This is a notably honest onboarding approach — most AI video tools give far fewer free credits. Paid plans start at approximately $12.99 per month for the Starter tier and scale up through Advanced and Pro tiers for higher credit volumes and priority queue access. The platform is accessible via web browser without any software installation.
Key Features
Character Consistency
Maintains subject appearance reliably across video frames. Upload a reference photo and generate videos where that person or character looks the same throughout the entire clip.
Reference-Subject Workflow
Combine a reference image with a text action prompt to generate video. Stronger subject identity preservation than standard image-to-video generation modes in competing tools.
1080p HD Output
Generate videos at full HD 1080p resolution with up to 16 seconds of runtime. Higher resolution than many competitors at the same price point, suitable for professional use.
Multi-Aspect Ratio Support
Generate in 16:9 (cinematic), 9:16 (vertical/social), and 1:1 (square) aspect ratios from the same prompt. No re-cropping or reformatting needed for different platforms.
80 Free Credits on Signup
New accounts receive 80 credits at registration — enough for multiple generations. Test the platform substantively before committing to a paid plan.
Multiple Generation Modes
Choose between 4-second, 8-second, and 16-second generation modes. Quick modes for fast iteration; extended mode for longer, more complex video sequences.
Pricing
Vidu uses a credit-based pricing model. Credit consumption varies by generation length and quality settings. The 80-credit free signup bonus allows meaningful evaluation before purchase.
| Plan | Price | Credits | Best For |
|---|---|---|---|
| Free (Signup Bonus) | $0 | 80 one-time credits | Evaluation, first-time users |
| Starter | ~$12.99 / mo | Monthly credit pool | Hobbyists, social media creators |

Alternatives to Vidu
If you need longer clips, integrated editing tools, or different motion characteristics, these alternatives are worth evaluating alongside Vidu.
Kling AI
Kuaishou’s video generator supports clips up to 2 minutes with motion brush and lip sync. The top choice when clip length is the primary requirement.
Runway ML
Gen-3 Alpha with motion brush, inpainting, and a full creative editing suite. The professional standard for studios needing generation and post-production in one platform.
Luma Dream Machine
Excellent physics simulation and cinematic camera motion via the Ray 2 model. Strong image-to-video support with 30 free generations per month.
Pika
Fast generation with strong style controls and a quick iteration cycle. Best for short-form social media content where turnaround speed matters most.
Frequently Asked Questions
What is Vidu?
Vidu is an AI video generation platform by Shengshu Technology, a Chinese AI startup with research ties to Tsinghua University. It generates video clips from text prompts and reference images, with a particular strength in character consistency — maintaining a specific person or character’s visual appearance reliably across video frames. Clips run up to 16 seconds at 1080p resolution, and the platform is accessible via web browser without any installation.
Is Vidu free?
New users receive 80 free credits on account creation, which is enough to generate multiple video clips and evaluate the platform’s output quality before purchasing a subscription. After those credits are used, a paid plan is required. Starter plans begin at approximately $12.99 per month. Unlike some competitors that offer recurring weekly or monthly free credits, Vidu’s free credits are a one-time signup bonus.
How long are Vidu videos?
Vidu generates clips in three lengths: 4 seconds, 8 seconds, and 16 seconds. The 16-second extended mode is available on paid plans and produces 1080p HD output. For longer productions, creators combine multiple Vidu clips in a video editor. The 16-second maximum puts Vidu between Luma Dream Machine (9 seconds) and Kling AI (2 minutes) in terms of native generation length.
What makes Vidu different from other AI video generators?
Vidu’s defining feature is its character consistency model and the associated reference-subject workflow. While most AI video tools allow you to animate a face from a photo, they often introduce visual drift — the subject’s appearance changes noticeably between frames. Vidu specifically trained its model to prevent this, making it the most reliable tool for generating multi-frame videos where a specific person or character needs to look the same throughout the entire clip.
Who made Vidu?
Vidu is developed by Shengshu Technology (生数科技), a Beijing-based AI startup founded in 2023. The company was co-founded by researchers with ties to Tsinghua University’s AI department and has raised significant venture capital from major Chinese technology investors. Shengshu Technology focuses exclusively on video generation and has positioned Vidu as a research-led product that competes technically with tools from larger companies like Kuaishou (Kling) and ByteDance.
What are the best alternatives to Vidu?
The best alternatives depend on your needs. Kling AI is the best choice when clip length is critical — it generates up to 2 minutes natively with motion brush and lip sync. Runway ML is the professional standard with integrated editing tools alongside generation. Luma Dream Machine produces excellent physics and camera motion quality with a generous free tier. Pika is best for rapid iteration on social media content. Vidu is uniquely strong when character identity consistency across frames is the priority — no other mainstream tool matches it on that specific capability.
