Terms of Use | Vidu Q4

Effective October 13, 2026. These terms form an agreement between you and Vidu Q4. By using the service, you agree to them.
You must be able to form a binding contract and provide accurate account information. You are responsible for activity in your account and must notify support@viduq4.org of suspected unauthorized use.
ViduQ4.org is an independent site, not affiliated with or endorsed by ShengShu Technology or Vidu. Vidu is a trademark of its owner. This studio uses only silent reference-to-video requests with reviewed nonhuman presets and fixed motion instructions. Scene previews are still images; generated results require human review before delivery.
Each request uses the credits shown before you submit it. The amount reflects the selected model, settings and other billable inputs. Prices are in USD unless stated otherwise; tax may be added. Paid subscriptions renew automatically at the displayed interval until cancelled through your account under Waffo subscriptions. Cancellation stops future renewals; the plan stays active until the end of the paid period. Cryptocurrency payments are one-time and never renew. Purchased credits roll over and remain available while the account stays active. Credit grants, promotional credits and plan features may change prospectively.
When you choose Waffo at checkout, Waffo Pancake acts as the merchant of record for your purchase and handles payment collection, applicable sales taxes and its own buyer refund review. You authorize recurring charges at the displayed amount and interval when you choose a subscription. Cancel future Waffo renewals in your account under Waffo subscriptions; cancellation preserves the paid period and unused purchased credits.
Waffo Pancake or NOWPayments (cryptocurrency) processes payments, depending on the method you choose at checkout. You authorize that provider to charge the selected payment method. Credits are returned to your balance for requests that definitely did not start or provider-confirmed terminal failures; uncertain provider outcomes remain held for reconciliation. Purchases are final and non-refundable except as described in our refund policy.
If you are in the European Economic Area, United Kingdom and Switzerland, you will be asked at checkout to agree that supply starts immediately and to acknowledge that you lose your right of withdrawal once it does.
Do not use the service for unlawful, deceptive, abusive, sexually exploitative, privacy-invasive, or rights-infringing material; to impersonate people deceptively; to bypass safety controls or rate limits; to reverse engineer protected systems; or to interfere with the service. We may suspend access when reasonably necessary to protect users or the service.
Content policy effective October 9, 2026.
This studio accepts only reviewed nonhuman presets with fixed motion instructions and audio disabled. Personal uploads, arbitrary references, custom prompts, real-person generation, voices and lip-sync are unavailable. This policy applies to generated results and use of the service. Do not submit, generate, or distribute:
Before a generation starts, we screen the fixed motion instructions using a local child-safety rule and Waffo’s automated prompt screening. A blocked or uncertain result does not proceed. If screening is unavailable, the request stops and may be retried later. These pre-generation stops do not charge credits.
Every new silent video is held in private storage and withheld from its owner until an authorized human reviewer has watched the entire clip. Results containing real people, human likenesses, lip-sync or other prohibited content are rejected before delivery, and reserved credits are returned. Only approved results become available to their account owner. Automated prompt and explicit-nudity checks supplement this review; they do not guarantee the absence of every violation.
Authorized administrators review screening records and reports, investigate the supplied information, and record their decisions and reasons. Depending on the evidence and seriousness, we may refuse a request or suspend generation access. A report alone does not automatically suspend another user. Accounts with a content restriction cannot submit new generation requests; billing, subscription cancellation, and appeals remain available. We may restore access after review of an appeal. This process does not automatically forfeit purchased credits or cancel recurring subscriptions; billing and refunds remain subject to the payment and refund terms.
Use Report content without signing in. Select a category and provide the affected link or request reference, what happened, and an optional contact email. Do not upload or reproduce illegal or graphic material. You receive a receipt number when the report is saved. To appeal, select “Appeal a moderation decision” and include the relevant receipt or account reference. We record reports and review outcomes in a restricted administrator queue.
We provide an initial human response within 3 business days when a contact email is supplied, including for photo or likeness misuse. Reports involving suspected CSAM, NCII, or imminent harm are prioritized. If an investigation needs longer, we explain the next steps and provide an update; this is a response commitment, not a guarantee that every investigation finishes within that period.
Effective October 9, 2026. This studio offers only reviewed nonhuman scene presets with fixed motion instructions and audio disabled. Custom prompts, image uploads, arbitrary references, real-person generation, voice input and lip-sync are unavailable. Generated clips remain private and pending until a human reviews the entire video before delivery. Do not submit, generate, or distribute:
Server controls restrict references and motion instructions to reviewed nonhuman presets and disable audio. Automated prompt screening and explicit-nudity checks supplement human review of generated clips. Automated ch
