Seedance 3 is an AI video generation platform designed to help creators produce cinematic video outputs from ideas, prompts, or reference assets. The tool supports multimodal inputs, allowing users to combine text prompts with image, video, and audio references in a single workflow. It offers a Creative Mode for refining concepts and can output video at 4K resolution. The platform is built around a streamlined public entry point called the Sunday frontend, which provides a lighter homepage focused on the core creation workflow rather than the full legacy generation workbench. Key capabilities include the ability to use multiple reference types simultaneously, compare membership tiers and one-time Star purchases, and access privacy, terms, help pages, and localized routes without entering the main application. New accounts start with free Stars for the first workflow, and users can earn additional Stars by completing their first successful AI video or by having community posts approved. Referral rewards and daily incentives are also available. The platform highlights these reward mechanics on public pages so visitors can understand the entry cost before signing up. Typical use cases involve creators moving from an initial idea, prompt, or reference asset toward a finished cinematic video. The workflow begins on the public homepage, which links to the core generator, memberships, community, help, and commercial guidance in a single crawlable route. Users can review product pages, compare memberships, learn reward mechanics, open the AI video workspace, and browse the community before deciding to sign in. The interactive app loads when JavaScript is available, while static HTML ensures that public routes remain understandable for crawlers, language-prefixed visits, and lightweight clients. Bots and users without JavaScript can still read route summaries and navigation.
