Seedance 2.0 (720p)
ByteDance · AI videoSeedance 2.0 (720p) is ByteDance's next-generation video model running at high resolution: it generates video with synchronized audio from text, images, video clips, and audio in one pass, using a unified multimodal architecture. Provider details and examples: https://replicate.com/bytedance/seedance-2.0-fast
Compared with earlier Seedance releases, 2.0 emphasizes multimodal references (multiple images, videos, and audio in one job), stronger motion and physics, optional video editing and extension workflows, and flexible duration and aspect handling on the provider side. It is aimed at creators who want native audio–video sync, dialogue in prompts (quoted speech for lip sync), and more control over consistency across shots.
On VidMachine, Seedance 2.0 (720p) is integrated via Replicate for project scene generation. We use 720p output at 9:16 for high-quality short-form delivery. Credits are 30 per second of requested scene duration, reflecting the higher resolution and quality.
Key features and benefits
Multimodal inputs (provider)
On Replicate, Seedance 2.0 can combine multiple reference images, video clips, and audio; prompts can reference them as [Image1], [Video1], [Audio1], etc. VidMachine's automated pipeline uses text-to-video and image-to-video (start frame, optional last frame) like our other models—advanced multi-asset references are available on the provider for custom workflows.
Native synchronized audio
Audio and video are generated together, so dialogue, effects, and music stay aligned with picture. You can describe speech in double quotes in prompts for lip-synced delivery. The provider also supports turning audio off for silent video if needed.
Editing and extension (provider)
The model supports describing edits to an existing clip or continuing a reference video with consistent characters and style. These flows are documented on ByteDance and Replicate; VidMachine focuses on standard scene generation from screenplay and frames.
720p Resolution
We call the model at 720p for high-quality vertical shorts (720×1280 at 9:16 per ByteDance's published resolution table). This provides significantly more detail than the 480p variant while remaining optimized for mobile viewing.
