Key Capabilities
Up to 4K Resolution
Seedance 2.5 produces output at up to 4K — four times the pixel density of the 1080p VIP tier — for deliverables that hold up on large displays and professional screens.
Cinema-Grade Motion Control
Advanced motion coherence and temporal consistency across frames. Complex camera movements, multi-character scenes, and fast-action sequences render with production-ready fidelity.
Native Audio Synthesis
Like all Seedance 2 models, 2.5 natively generates audio alongside video — ambient soundscapes, foley, and phoneme-accurate lip-sync in 8+ languages without a separate pipeline.
Multi-Modal Reference
Condition generation on up to 9 reference images, 3 video clips, and 3 audio files to maintain consistent character identity and scene style across shots.
Text to Video
Generate 4K video directly from a text prompt. Rich scene descriptions, director-mode scripting, and aspect ratio controls are all supported.
Image to Video
Animate any still image to 4K video with precise motion control. The 2.5 model delivers the highest visual consistency between input image and output video in the Seedance family.
