Kling 4.0 vs Seedance 2.5. I ran three tests through both models on Higgsfield (15 seconds, 720p, 16:9, no reference images) and compared animation, realism, sound, famous IP and price. Both models got the same prompt, except the Star Wars test, where Seedance's IP protection meant it got an IP-safe rewrite. The totals for all three test videos: Seedance 2.5 came to $15.75, Kling 4.0 came to $5.10.
