What is Kling 4.0?
Kling 4.0 is Kuaishou's latest AI video model, officially released on October 15, 2026. Compared with earlier versions, it is more stable in large motion and complex camera moves, natively generates up to 30 seconds, and accepts mixed image, video, and audio references.
Why use Kling 4.0 on a canvas instead of a single prompt box?
Longer videos are made of several scenes that need the same characters, products, and voices throughout. On a Pictell canvas, references and finished clips are nodes you can connect again, so each scene builds on the last instead of starting from zero.
Which Kling 4.0 modes are available on Pictell?
Four: Kling V4.0 for text-to-video, Kling V4.0 Image for image-to-video with a first frame, optional last frame and in-between keyframes, Kling V4.0 Reference, and Kling V4.0 Edit. The sample canvas uses Reference; you can switch models inside the video node.
Can I edit an existing video with Kling 4.0?
Yes. Kling V4.0 Edit rewrites a source video from a text instruction while keeping its motion. Add up to 10 reference images and refer to them as @Video1 and @Image1. Length follows the source clip, up to 30 seconds. Original sound is kept by default, or you can generate new synced audio. Use Kling V4.0 Reference when you want a new scene that only borrows the camera or performance.
How many reference files can I use?
Kling V4.0 Reference accepts up to 10 images, 5 videos, and 3 audio clips per generation. Refer to them in the prompt as @Image1, @Video1, and @Audio1.
How long are clips, and what quality is supported?
Each generation runs 3 to 30 seconds at 30 fps, in 720p or 1080p. Aspect ratios are 16:9, 9:16, 1:1, and 21:9, and Reference mode also supports auto.
Does Kling 4.0 generate audio?
Yes. Text-to-video and image-to-video always return synced stereo audio. Video edit keeps the original sound by default, or can generate new synced audio. In Reference mode, you can keep or mute the reference video's sound.
Does Pictell support Kling 4.0 keyframes or 4K?
Image-to-video accepts a first frame, an optional last frame, and up to 8 in-between keyframes, 10 images in total. Output is 720p or 1080p. 4K and 10-bit HDR are not available.
Do I need an account to generate?
You can preview the canvas on this page. Creating a project and generating video requires a Pictell account with available credits.
