Seedance 2.5, online — 30 seconds, native 4K
ByteDance's newest video model breaks three world records: 30-second single shots, 50 multimodal references, and native 4K output. WaveVideo brings it to creators worldwide — no Chinese phone number, no clunky signup.
What's new in Seedance 2.5
- 30-second single-shot generation. Most competitors cap at 8–15 seconds per clip. Seedance 2.5 generates a continuous, coherent 30-second shot in one pass — no stitching, no drift.
- Native 4K output. Not upscaled — the model renders at 4K natively, with the detail to survive a big screen.
- 50 reference inputs. Feed it images, video clips and audio together (the most of any model globally) to control characters, scenes, lighting and motion style.
- Audio-video joint generation. Synchronized sound generated together with the visuals.
Seedance 2.5 was unveiled at the 2026 Volcano Engine FORCE conference and released in early July 2026. Official access currently requires a Chinese Dreamina/Jimeng account — WaveVideo removes that barrier.
