Kling 4.0

Kling 4.0 supports both text-to-video and image-to-video input. You can upload a first frame and, optionally, a last frame to direct the destination of a shot. Duration is selectable from 5 to 30 seconds, and resolution options include 720p, 1080p, and 4K. Audio can be enabled when a scene needs dialogue or atmosphere. The workspace displays credit estimates before generation, and 4K output requires an existing annual plan. Generated clips can be previewed, downloaded, and revisited in My Creations alongside useful prompt versions.

Kling 4.0 is presented for several practical scenarios. For product concepts, you can start with a clear product image, describe the surroundings, and verify labels, proportions, and branding in the result. For story development, you can explore a scene from your script and compare framing and pacing before deciding which idea deserves more production time. For social content, you can develop an opening moment, match the composition to your publishing format, and keep the main action readable on a small screen. Other suggested uses include scene studies and campaign concepts.

The page states that Kling 4.0 generations use credits. A generation example shows 160 credits, and larger output resolutions use more credits. The workspace displays a credit estimate before you start generating. The page also notes that the existing annual-plan requirement applies to 4K output. No other pricing details are provided on the page.
