Affordable Seedance 2.0 API

Access ByteDance Seed's Seedance 2.0 on Velokey — native multi-modal audio-video joint generation from text, image, audio, and video, with strong real-world motion and synchronized binaural sound, all through a unified endpoint and below-list pricing.

Meet Seedance 2.0 and its API access

Seedance 2.0 is ByteDance Seed's new native multi-modal audio-video generation model, officially released in China in early February 2026 as the successor to Seedance 1.0 and 1.5 Pro. Built on a unified, efficient, large-scale architecture for multi-modal audio-video joint generation, it accepts four input modalities — text, image, audio, and video — and supports comprehensive reference and editing: subject control, motion manipulation, style transfer, special effects, creative content generation, and video extension, used standalone or combined. Velokey provides an affordable, easy-to-integrate Seedance 2.0 API: a unified video generation endpoint, one API key, and below-list pricing for production creative pipelines, marketing teams, and automation tools.

Real-world complexity and natural motion

Big gains in human motion modeling deliver naturalness, temporal coherence, and physical plausibility — high-fidelity complex interaction scenes obey real-world motion laws, with realistic close-up details, strong multi-subject interaction, and a usability rate clearly higher than recent commercial models.

Multi-modal control, editing, and continuation

Combine text, image, video, and audio references to control frame composition, cinematography, motion rhythm, and acoustics. Strong instruction-following keeps subject identity consistent across complex scripts, with autonomous shot sequencing, plus new video editing of specific clips, characters, actions, or plot, and video continuation.
