Kling 4.0 AI Video Generator

Kuaishou’s Kling 4 and Kling 4.0 Omni in the Renoise Canvas: 3–30 second shots with native audio, 720p up to 4K, and 21:9 framing.

What Kling 4.0 does in Renoise

3–30 seconds per shot

Pick any whole second from 3 to 30. A 30-second take comes out of one generation, no stitching.

720p up to 4K

Render at 720p or 1080p, or choose the 2K and 4K tiers, which are upscaled output.

Native audio, always on

Dialogue, effects and ambience come with every clip. Kuaishou says the audio is two-channel stereo with tighter lip sync.

21:9 ultrawide

Frame shots in 21:9, 16:9, 9:16 or 1:1 for film, YouTube, Reels and feeds.

First and last frames

Start from your own first frame, or set both ends and let Kling 4.0 animate the move between them.

Readable on-screen text

Kuaishou says signs, titles and logos stay legible in English, Chinese, Japanese, Korean and more.

Kling 4.0 vs Kling 4.0 Omni

Renoise lists two Kling 4 models at the same price and with the same caps: 3–30 seconds, 720p to 4K, four aspect ratios and native audio. The only difference is how you steer the shot.

Use Kling 4.0 for pure text-to-video, or when you already have the exact first frame (and, optionally, the last). Use Kling 4.0 Omni when a person, product or place from your images has to appear in the video: it takes up to 10 reference images. One task uses either frames or reference images, not both.

Kling 4.0

Text, first frame, first + last frame

Best when the opening image is fixed or you only have a prompt.

Kling 4.0 Omni

Up to 10 reference images

Best for keeping a character, product or set consistent across the shot.

Try Kling 4.0 in Renoise

A whole dogfight in one take. Canyon run, ice tunnel, missile hit and HUD overlay, all in one 15-second generation.

Claymation with a story. A hand-sculpted look, consistent characters and a full gag across 15 seconds.

Talking to camera. A selfie-style vlog intro with spoken English lines generated together with the picture.

Signs you can read. English and Japanese neon text stays sharp while the camera pushes in through the rain.

Fast action in the rain. A bride on horseback racing through city traffic, with rain, spray and motion blur.

A 30-second ride. One 30-second generation that follows a rider from old-town lanes to a coastal sunrise.

FAQ

1.What is Kling 4.0?

Kling 4.0 is the fourth-generation video model from Kuaishou’s Kling AI. It makes 3–30 second clips with native audio from a prompt, a first frame, first and last frames, or reference images. In Renoise it comes as two entries, Kling 4.0 and Kling 4.0 Omni.

3.What is the difference between Kling 4.0 and Kling 4.0 Omni?

They share the same price, durations, resolutions and ratios. Kling 4.0 works from text, a first frame, or first and last frames. Kling 4.0 Omni also accepts up to 10 reference images to keep a character, product or scene consistent. A single task uses frames or reference images, not both.

4.How long can a Kling 4.0 video be?

Any whole number of seconds from 3 to 30 in one generation. Kuaishou has announced extending a video up to 2 minutes as coming soon; that is not available in Renoise.

5.Does Kling 4.0 support 4K?

Yes. Renoise offers 720p, 1080p, 2K and 4K for Kling 4.0, where 2K and 4K are upscaled output. Kuaishou’s 10-bit HDR output is listed as coming soon and is not available in Renoise.

6.Does Kling 4.0 generate sound?

7.How much does Kling 4.0 cost?

In Renoise, Kling 4.0 and Kling 4.0 Omni cost 26 credits per second at 720p, 38 at 1080p, 46 at 2K and 76 at 4K. A 5-second 720p clip is 130 credits; a 10-second 1080p clip is 380 credits. See pricing for plans.

8.Can I use Kling 4.0 through an API?
