PHYSIX OBSERVATION

Kling pushes single-generation length to 30 seconds and layers on 4K HDR, aiming squarely at professional editing workflows—AI video is shifting from toy to productivity tool. Multimodal references and continuation features lower the barrier to long-form creation, but with Flash leading and the official release not due until October, compute cost remains the real bottleneck to scaled deployment.
