Kling 4 AI Video Maker

Kling 4 (official name Kling 4.0) is the AI video model from Kling AI, the AI video business of Kuaishou, available to everyone since October 15, 2026. One generation runs up to 30 seconds with stereo sound, takes up to 10 keyframes or 15 references, and edits videos you already have.

Sign-up on Seadanse is free and comes with 40 starter credits. You can check Seadanse pricing to see how Kling 4 runs on credits at 35 per second at 720p.

It costs 35 credits per second at 720p and 53 at 1080p. When you bring a video, its seconds count too, at 21 credits per second at 720p and 32 at 1080p, so editing a 7-second clip into an 8-second 720p video costs 336 credits. The estimate shows beside Generate before you submit, credits are charged only when the video is done, and a failed or timed-out generation refunds automatically. View details at Seadanse pricing.

Your video can be 3 to 30 seconds per generation, any whole second, in one continuous generation.

It supports 720p and 1080p resolutions. You can choose between 21:9, 16:9, 9:16, or 1:1 aspect ratios at 24 fps, all available for MP4 download.

Yes. It creates two-channel stereo audio with dialogue, sound effects, ambient sound, and music in the same pass as the picture, with lip sync. It supports Chinese, English, Japanese, Korean, Spanish, Portuguese, German, French, and Hindi, plus American, British, and Indian English accents.

You can use up to 15 references in one video (up to 10 images, 5 videos of 30 seconds in total and 3 audio clips of 5-30 seconds each). For keyframes, you can place up to 10 images on the timeline to control the first, middle, and last frames.

Kling 4 extends length from 15 to 30 seconds and introduces 10 keyframes and 21:9 ultrawide output. References grow to 15, audio upgrades to two-channel stereo, dialogue expands to 9+ languages, and video editing is now built-in.

Pick Kling 4 for a 30-second take you plan second by second with 10 keyframes, or for a dialogue-heavy scene. Since the Seedance 2.5 AI video maker is on Seadanse with the same credit balance, you can run one prompt on both models. You can also use our AI video cost calculator for Seedance 2.5 to compare your project costs.

Yes. Upload one clip of 3-30 seconds and change expressions, motion, a character or object, the background, the camera, the style, the weather, or the colors. To recreate a trend, add the trending video as a reference video and rebuild its pacing and shot structure around your own character or product.

Give each reference a role and call it by its tag, such as @Image1 or @Video1. Write the beats by the second, such as '0-8 seconds wide shot, 8-15 seconds slow push to close-up,' put each spoken line in quotes, and name the specific picture style you want.
