Each video model uses a different image input field: - kling-o1-pro/std: first_frame (not image) - kling-elements-pro/std: images (array) - minimax-hailuo: image, duration fixed at "6" Also: - kling-elements requires slug aspect ratios (square_1_1, etc.) - Remove wan-2.5 and runway-gen4 which return 404 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
