PHYSIX OBSERVATION
With 30-second single-pass generation plus 2-minute extensions, Kling pushes AI video from short clips toward continuous narrative, striking directly at professional production pipelines in advertising and short dramas. Integrating MCP/CLI and teasing an API shows Kuaishou is turning Kling from a creation tool into embeddable workflow infrastructure, staking out position in the enterprise market. For creators, multi-asset combinations and keyframe control lower the cost of repeated trial and error, but the real barrier has shifted from generation capability to directorial thinking.
