Kling4

Kling4 is an independent AI video studio that aggregates 18 video generation models from seven brands, including Kuaishou’s Kling 4.0, into a single model picker.

• Kling 4.0 capabilities: generate videos up to 30 seconds at 4K resolution, with two‑channel stereo audio, accurate lip‑sync, and readable in‑video text.
• Control: steer generation with up to 10 keyframes and 15 reference assets (images, video clips, voice samples, subject elements).
• Multilingual sound: output speech in English, Spanish, Portuguese, French, German, Chinese, Japanese, Korean, Indonesian and more.
• Editing: edit across up to 5 input clips and extend videos (coming soon).

Target audience includes content creators, marketers, educators, and businesses needing fast, high‑quality video production without complex editing workflows.

Value proposition: a unified interface that lets users experiment with multiple AI video models, access free credits to try the studio, and upgrade to paid plans for higher resolutions, longer generations, and model access.
