Tried the same fruit juice ad prompt on Kling 4.0, Seedance 2.0, and MiniMax H3. One generation each. Interesting how differently they handled the layout. H3 went with a bigger fruit arrangement, more prominent packaging, and a pretty clean balance between the "LUCKY" text and the products. Which one looks better to you?

Kling 4.0 can generate videos up to 30 seconds long, with dialogue, voice matching, lip sync, and sound effects. Here’s what you can do: Combine up to 15 references, including images, videos, saved characters, and voice recordings. Use Omni to bring those references together in one prompt. Use Keyframes to guide specific moments with up to 10 images along the timeline. Edit existing footage by replacing characters, changing backgrounds, or adding new elements. Create fast action scenes with complex camera movements. Every scene in this video was generated with Kling 4.0. How well did it do? 👀

Kling 4.0 is pushing AI filmmaking even further. From realistic motion to smooth camera work and advanced reference controls, @Kling_ai makes it easier to turn creative ideas into cinematic videos. More control, longer clips, and endless creative possibilities. #ad https://t.co/BpT8XMVaMY

Kling 4.0 is fully live for all users ✨ In the Kling Cards clips, the motion holds up well even during complex movement. Native 30s generation means scenes stay continuous instead of being stitched together, and Omni Reference adds real consistency control. To me, the practical upgrades matter more than the hype. #KlingAI #Kling4

Kling 4.0 is officially available to everyone! Fast-paced action is where AI video usually struggles, but the motion control here looks seriously impressive. Complex movements feel smoother, the action stays coherent, and the camera keeps up without losing that cinematic feel. AI filmmaking is moving fast with @Kling_ai #KlingAI #Kling4 #AIVideo

Same prompt. Same fox reference. 30 seconds, one generation each. Left: Seedance 2.5 Right: Kling 4.0 Kling kept the character locked in every shot: jacket, satchel, clay look. It also hit every beat in the prompt, the iron included. Seedance has the better cinematography: moodier light, more physical motion, better tail and cloth. But the fox slowly drifts toward a real fox. Which one would you pick for a series? (Seedance is the 480p draft, Kling is 720p.)

The support for up to 15 Omni Reference inputs and 10 keyframes also gives creators more flexibility to bring their ideas to life. AI video generation is moving fast, and @Kling_ai is giving creators even more ways to tell stories with greater creative control. 🔥 #KlingAI #Kling4

30 seconds is useful when the shot actually needs 30 seconds. Kling 4.0 can generate the sequence natively instead of building the story out of a stack of short clips. More room for the scene to develop without breaking the flow. https://t.co/wZIfs2Gcbp
