- What is Kling 4.0 and how is it different from Kling 3.0?
- Kling 4.0 extends single generations to 30 seconds, up from Kling 3.0's shorter clips, adds native 4K output with 10-bit HDR, and generates dual-channel stereo audio in the same pass as the video instead of requiring a separate audio step.
- Is Kling 4.0 available now, or only Kling 4.0 Flash?
- Right now, Kling 4.0 Flash is live, generating up to 20-second clips at up to 720p in 8-bit SDR. The full Kling 4.0 experience, with 30-second 4K HDR generations, is rolling out this month, check your plan for current availability.
- How much does Kling 4.0 cost on ImagineArt?
- Your first video is free, no card required. Beyond that, generations draw from your ImagineArt credits or subscription plan.
- How does Kling 4.0 compare to Runway Gen-4.5, Veo 3 and Sora 2?
- Independent benchmark rankings for Kling 4.0 specifically haven't been published yet since the full version is still rolling out. What's confirmed from Kuaishou's own release notes is longer native generations (30 seconds, versus most competitors' 5 to 10) and built-in multilingual audio; we'll update this comparison once third-party benchmarks land.
- Does Kling 4.0 generate native audio, and in which languages?
- Yes. Kling 4.0 generates dual-channel stereo audio in the same pass as the video, with multilingual dialogue support across nine languages.
- How long can a Kling 4.0 video be, and can clips be extended or edited afterward?
- A single generation runs up to 30 seconds, extendable to two minutes total, with selective re-editing of expressions, camera angles, backgrounds and dialogue without a full regeneration.
