Kling 4.0 Brings Native Audio, Keyframes to fal

Kling’s biggest leap may be production control rather than visual quality alone, pushing AI video closer to repeatable storytelling workflows. Developers should remain cautious until fal publishes endpoints, pricing, and performance benchmarks.

• –Native 30-second generation and up to 10 keyframes could reduce tedious clip stitching.
• –Up to 15 multimodal references should improve character, object, and scene continuity.
• –Stereo audio, multilingual speech, and better lip sync expand use cases beyond silent visual prototyping.
• –4K and 10-bit HDR output raise the ceiling for commercial and cinematic work.
• –fal already hosts a broad Kling lineup, so API availability could make Kling 4.0 immediately useful in production pipelines.
