Seedance 1.5 Pro

Seedance15.ai is a web-based AI generation platform built around the “Seedance 1.5” model, focused on creating professional-looking videos with synchronized audio in a single generation flow. It supports text-to-video and image-to-video creation with options like resolution, aspect ratio, and duration, and highlights features such as precise lip-sync alignment, multilingual voice synthesis (including dialect/accents), cinematic camera movement control, and contextual ambient sound effects. Alongside video generation, the site also offers text-to-image generation and an AI image editor. The service uses paid plans with usage limits/credits, and also sells one-time credit packs; subscription credits reset monthly, while one-time credit packs are described as non-expiring. The Terms state users retain rights to their inputs and own the generated videos (including for commercial use), and the platform positions itself as independent (not affiliated with third parties).
