Perfect Corp. announced on October 23, 2026, that it has integrated Kuaishou Technology's newly released Kling 4.0 API across its YouCam mobile and web lineup, making YouCam one of the first platforms to feature the advanced AI video model.
Storyboarding with 10 Keyframes
Designed for longer storytelling, Kling 4.0 moves beyond the traditional first-and-last-frame limitation by allowing users to configure up to 10 keyframes. Instead of describing an entire sequence in a single prompt, creators can define exact visual elements at precise points within the video timeline.
Thirty-Second Video with Dialogue and Sound
In addition, the integration delivers up to 30 seconds of continuous video in a single pass, complete with lip-synced dialogue and stereo sound. The model processes multiple reference assets simultaneously—including photos, multi-angle character sheets, storyboards, and motion or camera movement references—ensuring consistent character faces, outfits, and product details throughout the generated sequence.
The integration gives creators and brands a streamlined way to produce cinematic short-form content directly through mobile and web environments. Perfect Corp. noted that these advanced keyframe and duration limits apply specifically to the YouCam platform's Kling 4.0 integration environment rather than legacy models or third-party implementations.
