Seedance 2.5's 30-second native + 50 multimodal references — H2 2026 video-AI duration + multimodal leadership shifts to Chinese-vendor stack

Seedance 2.5 (early July 2026 launch) at 30-second native clips + 50 multimodal references + local re-draw editing represents three-dimension capability leap. Combined with HappyHorse 1.0 leading AA without-audio leaderboard, the H2 2026 video-AI category leadership concentrates at Chinese-vendor stack across multiple capability dimensions.

ByteDance Seedance 2.5's three-dimension capability leap (duration + multimodal references + local editing) reshapes video-AI procurement-evaluation matrix.

The Chinese-vendor cross-leaderboard leadership

HappyHorse 1.0 from Alibaba ATH at AA without-audio rank 1 + Seedance 2.0 at AA with-audio rank 1 together establish Chinese-vendor leadership pattern across multiple video-AI capability dimensions. The cross-leaderboard concentration represents structurally different competitive landscape than H2 2025 baseline.

The jurisdictional-evaluation procurement implication

H2 2026 to 2027 video-AI procurement should weight jurisdictional-evaluation explicitly alongside capability + cost dimensions. Chinese-vendor leadership requires structured evaluation framework that Western-vendor procurement traditionally hasn't needed. Combined with Veo 3.1 enterprise-procurement stability positioning, H2 2026 video-AI procurement architecture substantively complexifies.
