How to use it
Seedance AI Video Generator is built on ByteDance's Seedance model series — designed specifically for production-grade video with capabilities that go beyond what general AI video tools offer. At the core is a combination of cinematic rendering quality, precise motion physics, and synchronized audio-visual generation.
Seedance 1.5 Pro is the foundation model for high-fidelity text-to-video and image-to-video workflows. It handles scene depth, natural camera movement, and coherent subject motion with strong visual consistency. Teams use it for product videos, brand content, creative prototypes, and social-first publishing.
Seedance 2.5 is the flagship choice when you need longer clips and richer reference control. It supports native 30-second generation, larger reference sets, and native synced audio in one pass—ideal for product demos, presenter videos, and reference-heavy ad variants.
The Seedance 2.0 Family pushes further into synchronized media. Seedance 2.0 delivers higher-quality multimodal generation with native audio and 1080p output, while Seedance 2.0 Fast trades some quality for speed. Both support reference images, reference videos, reference audios, adaptive framing, and lip-sync-oriented generation for talking-head clips, AI avatars, dubbed ads, and presenter-format content.
Consistent character animations are another defining capability. Unlike many AI video models that lose subject identity across frames or scenes, Seedance maintains stable facial features, body movement, and visual style throughout multi-scene sequences. This is essential for brand ambassadors, spokesperson videos, and serialized short-form content.
For text-to-video, structured prompts that specify scene composition, motion type, lighting, and emotional tone consistently improve output fidelity. Clear description of what moves, how it moves, and what stays still helps the model render scenes that match creative intent.
For image-to-video, start with a high-quality source image with a clear focal subject. Seedance builds motion and depth from the visual context in the image, so sharper source inputs produce smoother, more coherent animated outputs.
