The first public release of ByteDance's AI video generation model. Seedance 1.0 introduced text-to-video generation at 480P resolution with basic motion capabilities. It demonstrated promising video quality but was limited to single-modal text input and short clip generation.
A significant quality improvement over 1.0. Seedance 1.5 introduced image-to-video generation, allowing users to animate static images. Motion consistency was notably improved, with smoother transitions and more natural character movement. Video quality and prompt adherence were both enhanced.
The professional-grade variant of 1.5 with enhanced character consistency and commercial-quality output. Seedance 1.5 Pro bumped resolution to 720P and supported longer video durations up to 10 seconds. It also introduced limited video extension capabilities, making it suitable for professional content creation.
Seedance 2.0 supports multimodal references, synchronized audio, editing, and extension, with clips up to 15 seconds. Seedance 2.5 builds on these capabilities.
Seedance 2.5 is ByteDance's audio-video generation model for longer stories, multimodal references, and precise editing. Create clips up to 30 seconds, extend a sequence, or refine selected moments while generating synchronized sound.
