Kling 4.0: plan a product reveal with keyframes

Kling 4.0 has a web creation workspace and documented API access for your product, tool, or agent. It supports text, image, and reference-based video generation, with whole-second durations of 3–30 seconds and 720p or 1080p output. For a gift box opening to reveal a watch, set the opening and closing images, then add ordered middle frames only where needed.

Closed, partly open, and fully open gift box. AI-generated storyboard concept, not a tested Kling 4.0 output.

Keep in mind: middle frames guide the sequence without individual timestamps; image mode follows the first frame’s aspect ratio. For input preparation, frame limits, and result checks, read the Kling 4.0 product-video keyframe guide.
