Seedance 2.5 drops with 4K, 30s video

ByteDance is positioning Seedance 2.5 directly against Runway Gen-3 and Kling by addressing the two biggest pain points in AI video: duration limits and character consistency.

• –Generating 30 seconds natively without stitching reduces temporal distortion, a major hurdle for narrative filmmaking.
• –Expanding reference capacity to 50 assets allows creators to inject detailed style guides and multi-angle character sheets, solving the 'identity drift' issue.
• –The inclusion of localized scene editing tools suggests a shift from pure prompt-to-video generation to interactive, production-ready canvas tools.
• –Keeping the model in enterprise beta first highlights ByteDance's strategy to monetize professional workflows before opening access to the public.
