These four aren't interchangeable — each has a different output character and cost-to-quality tradeoff, and picking wrong means worse ads and wasted credits. The one-line map: Seedance 2.0 = product-focused volume testing (~$2.44 per 8-second clip); Kling 3.0 = motion and material fidelity plus image-to-video and motion copy; Veo 3.1 = photorealistic lifestyle scenes for scaled winners; Wan 2.7 = stylized motion and modular segments. On paid social the first second decides everything, so your model choice for the hook frame carries more weight than any other part of the ad. In v4v all four run in one workspace on one credit balance — switching is a dropdown.
