Introduction
Vidu 2.0, developed by Shengshu Technology (生数科技), has rapidly gained traction as one of the leading AI video generation platforms in 2026. Whether you are evaluating the platform for the first time or have just signed up, you likely have practical questions that the marketing pages do not fully answer.
This FAQ compiles the most common questions about Vidu 2.0, organized by topic. The answers are based on the platform’s current specifications as of March 2026 and reflect both official documentation and practical user experience.
Video Specifications
Q: What is the maximum video length Vidu 2.0 can generate?
A: Vidu 2.0 can generate videos up to 32 seconds in a single generation pass. This is the longest single-generation duration available on any mainstream AI video platform as of March 2026.
However, maximum duration varies by plan:
- Free plan: Up to 8 seconds
- Standard plan: Up to 16 seconds
- Pro plan: Up to 32 seconds
- Enterprise plan: Up to 32 seconds (same as Pro)
Note that longer generations consume proportionally more credits. A 32-second clip at Cinema quality uses approximately 55 credits, compared to 5 credits for a 4-second Standard quality clip.
Q: What resolutions does Vidu 2.0 support?
A: Vidu 2.0 supports the following output resolutions:
| Resolution | Aspect Ratio | Available On |
|---|---|---|
| 720p (1280×720) | 16:9 | All plans |
| 1080p (1920×1080) | 16:9 | Standard, Pro, Enterprise |
| 1080p (1080×1920) | 9:16 (vertical) | Standard, Pro, Enterprise |
| 1080p (1080×1080) | 1:1 (square) | Standard, Pro, Enterprise |
| Custom aspect ratios | Various | Pro, Enterprise |
The free plan is limited to 720p. All paid plans support 1080p in standard, vertical, and square formats. 4K output is not currently available but has been mentioned in Shengshu’s public roadmap.
Q: What frame rate does Vidu 2.0 generate?
A: The native generation frame rate is 24 fps (frames per second), which is the standard cinematic frame rate. Vidu offers frame interpolation to 48 fps on Pro and Enterprise plans, which produces smoother motion at the cost of some additional processing time and a slight softening of fine detail.
Q: What file formats can I export?
A: Vidu 2.0 exports in the following formats:
- MP4 (H.264): Default format, widely compatible
- MP4 (H.265/HEVC): Smaller file size, better quality at equivalent bitrate
- WebM (VP9): For web use
- ProRes 422: Available on Pro and Enterprise plans, for professional editing workflows
Q: Can I generate videos longer than 32 seconds?
A: Not in a single generation pass. To create longer content, you need to generate multiple clips and edit them together in external software. Vidu’s “storyboard mode” on Pro plans helps with this by allowing you to plan and generate a sequence of connected clips, though each individual clip is still limited to 32 seconds.
Shengshu has indicated that longer generation durations are on the roadmap, with 60+ seconds expected in a future release.
Generation Modes
Q: What is the difference between Standard, Enhanced, and Cinema quality?
A: The three quality tiers trade generation speed and credit cost for output quality:
| Quality Tier | Generation Time | Credit Multiplier | Best For |
|---|---|---|---|
| Standard | ~1 minute per 8s | 1.0x | Iteration, concepts, drafts |
| Enhanced | ~2 minutes per 8s | 1.5x | Social media, general use |
| Cinema | ~4 minutes per 8s | 2.4x | Professional production, final output |
Standard generates quickly but with lower detail, simpler lighting, and less refined motion. It is ideal for exploring concepts and iterating on prompts.
Enhanced is the quality level most users will find sufficient for published content. It balances detail, generation speed, and credit cost.
Cinema is the highest quality tier, available only on Pro plans. It produces the most detailed output with the best physics simulation, lighting, and temporal coherence. Use it for final production clips.
Q: What is the physics engine and how do I use it?
A: Vidu 2.0’s physics engine is a simulation layer that conditions the video generation process on physical calculations. It produces more realistic fluid dynamics, object interactions, and environmental effects.
The physics engine is automatically active on Cinema quality generations for Pro plan users. You do not need to enable it manually. On Standard and Enhanced quality, a lighter version of the physics conditioning is applied.
You can influence physics behavior through your prompts:
- Specifying materials (“glass vase,” “heavy stone,” “silk fabric”) helps the physics engine apply appropriate properties
- Describing environmental conditions (“strong wind,” “heavy rain,” “zero gravity”) activates relevant simulation modes
- Including interaction descriptions (“water splashing against rocks,” “ball bouncing off a marble floor”) triggers compound physics simulation
Commercial License
Q: Can I use Vidu-generated videos commercially?
A: Commercial usage rights depend on your plan:
| Plan | Commercial Use |
|---|---|
| Free | No — personal and educational use only |
| Standard | Limited — small-scale commercial use (individual creator content, small-business marketing, social media) |
| Pro | Full — unrestricted commercial use including broadcast, advertising, and client work |
| Enterprise | Full — with custom licensing terms and additional IP protections |
Q: Do I own the copyright to videos I generate?
A: Under Vidu’s current terms of service:
- You own the rights to your prompts and input materials (reference images, scripts)
- You receive a commercial license to use the generated output (on applicable plans)
- Copyright ownership of AI-generated content remains a legally evolving area in most jurisdictions. Vidu’s terms grant you rights to use the output but do not make definitive copyright ownership claims, as the legal frameworks in most countries have not fully addressed AI-generated content ownership
For professional use where copyright ownership matters (advertising, broadcast, client work), consult legal counsel regarding your jurisdiction’s current position on AI-generated content rights.
Q: Is there a watermark on generated videos?
A: Yes, on the Free plan — a visible “Vidu” watermark appears in the lower-right corner of all generated videos. On all paid plans (Standard, Pro, Enterprise), no visible watermark is applied.
All plans include invisible metadata identifying the content as AI-generated, in compliance with emerging AI content labeling regulations.
Q: Can I use Vidu-generated content on YouTube, TikTok, and Instagram?
A: Yes, on all paid plans. The Standard plan’s limited commercial license covers social media publication. The Free plan permits personal social media use but not monetized content.
Note that some social media platforms have their own policies regarding AI-generated content disclosure. YouTube, for example, requires creators to disclose when content is generated by AI. Compliance with platform-specific policies is the user’s responsibility.
Content Moderation
Q: What content restrictions does Vidu have?
A: Vidu operates under Chinese content moderation requirements, which differ from Western platforms. Key restrictions include:
Restricted content:
- Politically sensitive content related to Chinese government, leadership, and national security
- Content that violates PRC laws and regulations
- Explicit sexual content
- Extreme violence and gore
- Content promoting illegal activities
- Deepfakes of real individuals without consent
Generally permitted:
- Artistic nudity in non-explicit contexts (more permissive than some Western platforms)
- Creative violence in cinematic/narrative contexts (action scenes, etc.)
- Fantasy and science fiction content
- Commercial and advertising content
- Educational content
Q: Can I generate content featuring real people?
A: Vidu restricts the generation of content depicting identifiable real individuals, particularly public figures. You can upload reference images of yourself or individuals who have provided consent for image-to-video generation. Generating content depicting public figures (politicians, celebrities, etc.) without their consent is prohibited.
Prompt Engineering Tips
Q: How do I write effective prompts for Vidu 2.0?
A: Effective Vidu prompts follow a structured format. Include these elements in order of priority:
- Camera/framing: “Close-up,” “wide shot,” “aerial view,” “tracking shot”
- Subject: Who or what is in the scene
- Action: What is happening
- Environment: Where the scene takes place
- Lighting: “Golden hour,” “neon lights,” “overcast,” “studio lighting”
- Mood/atmosphere: “Melancholic,” “energetic,” “serene,” “tense”
- Style: “Cinematic,” “documentary,” “music video,” “commercial”
Example of a weak prompt:
“A woman walking in a city”
Example of an effective prompt:
“Medium tracking shot following a young woman in a red dress walking confidently through rain-slicked city streets at night, neon signs reflecting on wet pavement, shallow depth of field, cinematic color grading with teal and orange tones, urban noir atmosphere”
Q: What prompt length works best?
A: Optimal prompt length for Vidu 2.0 is 40–100 words. Shorter prompts give the model too much interpretive freedom, producing unpredictable results. Significantly longer prompts (200+ words) can cause the model to prioritize some elements while ignoring others.
The sweet spot is a detailed but focused description that covers the essential visual elements without overloading the model with contradictory or excessive detail.
Q: Does Vidu understand non-English prompts?
A: Vidu accepts prompts in English and Chinese (Mandarin). English prompts tend to produce more consistent results for Western-style content, while Chinese prompts may produce better results for content featuring East Asian subjects, architecture, and cultural contexts.
Other languages are not officially supported and may produce unpredictable results. If you work in a non-supported language, translating your prompts to English generally produces better outcomes.
Q: How do I maintain style consistency across multiple generations?
A: Three approaches:
- Style reference images: Upload a reference image that defines your visual style. Vidu will attempt to match the color palette, lighting, and aesthetic.
- Consistent prompt language: Use the same style descriptors across all prompts for a project (“cinematic, teal and orange color grading, shallow depth of field, 35mm film grain”).
- Style locking (Pro plan): The style lock feature allows you to designate a generation as a style anchor, and subsequent generations will match its visual characteristics more closely.
API and Technical
Q: Does Vidu have an API?
A: Yes. API access is available on Standard (basic, rate-limited), Pro (full), and Enterprise (dedicated) plans. The API supports:
- Text-to-video generation
- Image-to-video generation
- Video-to-video transformation
- Generation status polling
- Result retrieval and download
API documentation is available at https://www.vidu.com (developer section).
Q: What are the API rate limits?
A:
| Plan | Concurrent Requests | Requests per Minute | Requests per Day |
|---|---|---|---|
| Standard | 1 | 5 | 100 |
| Pro | 5 | 20 | 500 |
| Enterprise | Negotiated | Negotiated | Negotiated |
Q: Can I fine-tune or customize the Vidu model?
A: Custom model fine-tuning is available only on Enterprise plans. This allows organizations to train the model on proprietary visual data (brand assets, product imagery, etc.) to produce output that aligns with specific brand guidelines.
Standard and Pro users can influence output through prompts, style references, and style locking but cannot modify the underlying model.
Account and Billing
Q: Can I switch between plans?
A: Yes, you can upgrade or downgrade at any time. Upgrades take effect immediately, with the price difference prorated for the current billing cycle. Downgrades take effect at the next billing cycle.
Q: Is there a free trial of the Pro plan?
A: Shengshu periodically offers free trial periods for the Pro plan (typically 3–7 days). Check the website for current offers. The Free plan itself serves as an indefinite trial of the platform’s core capabilities.
Q: Do unused credits roll over?
A: Partially:
- Free: No rollover
- Standard: Up to 200 credits roll over to the next month
- Pro: Up to 1,000 credits roll over to the next month
- Purchased credit packs: No expiration
Q: Can I get a refund?
A: Unused credit packs purchased separately can be refunded within 14 days. Monthly subscription fees are not refundable for the current billing period, but you can cancel to prevent future charges.
Getting Started
Q: How do I sign up?
A: Visit vidu.com and create an account with email or Google/Apple authentication. The Free plan is activated immediately — no credit card required. Paid plans can be activated from the account settings.
Q: What is the best first project for a new user?
A: Start with something you can visually evaluate: a short (4–8 second) clip of a subject you know well. This allows you to assess Vidu’s output quality against your own visual knowledge. Good first projects include:
- A landscape or cityscape at a specific time of day
- A simple character action (walking, sitting down, turning to look at something)
- A product shot (an object on a surface with specific lighting)
- An atmospheric scene (rain, fog, sunrise)
Generate 3–5 variations of the same prompt to understand how the model interprets your descriptions and how much variation exists between generations.
Q: Where can I find example prompts and community work?
A: Vidu maintains a community gallery on the platform showing featured generations with their prompts. Additionally, the Vidu Discord server and Reddit community (r/vidu) share prompts, tips, and workflows. These communities are valuable resources for learning effective prompt engineering.
