Kling AI — Video Generator with Kling 4.0, 3.0 & Motion Control

What Is Kling AI?

Kling AI is a family of AI video generation models developed by Kuaishou. It can transform written prompts into videos, animate still photographs and generate scenes involving characters, objects and camera movement. The tools can be used for short films, social media content, product videos and visual storytelling.

Neuromia provides access to several Kling generations, including Kling 4.0, 3.0, 2.6, 2.5 Turbo and 2.1. Dedicated Motion Control and Avatar tools are available as well. Each model serves different production needs, and all use Neuromia's shared credit balance.

Kling 4.0: What's New

Kling 4.0 introduces video generation lasting 3 to 30 seconds in a single pass, with output at 720p or 1080p. Native audio accompanies the generated video, and lip synchronization supports spoken scenes.

According to the developer's language list, dialogue generation supports Chinese, English, Japanese, Korean, Spanish, Portuguese, German, French and additional languages. Russian is not explicitly listed there, so support for Russian dialogue should not be treated as confirmed.

Two features expand creative control: advanced references and keyframes. They allow users to specify source materials and the visual progression of a scene instead of depending entirely on a general text description.

Available aspect ratios include 16:9, 9:16, 1:1 and 21:9. The format can also be selected automatically based on input materials.

References: Combine Images, Video and Voices

Kling 4.0's References mode lets creators combine different types of source materials within one generation.

• Up to 10 uploaded images.
• Up to 5 videos, each 2–30 seconds long, with a combined duration of up to 30 seconds.
• Up to 7 characters or elements. Each character can be defined using 2–4 photos or one 3–8-second video.
• Up to 3 voices.
• A maximum of 15 total materials across the workflow.

Prompts refer to attached assets using @image_1, @video_1, @name and @voice_1.

For example, upload a product photograph and a reference video showing the intended camera movement. The prompt can request the product from the photograph while following the reference video's pacing and composition.

The same approach works for replacing a character or background while borrowing motion from an existing clip. There is also an option to preserve the original audio from reference video.

References are useful when a project needs specific visual assets, recurring characters or a particular camera style.

Keyframes: Plan How the Scene Develops

Keyframes mode lets you provide the first frame, the last frame and up to eight intermediate frames. Kling generates the transitions between those visual states.

Consider a product reveal. The opening frame shows a closed package. An intermediate frame shows it opening, another reveals the product, and the final frame presents a close-up.

Instead of asking for the entire sequence in one sentence, you define its important stages. References determine which source assets appear, while keyframes help describe how a scene progresses over time.

Kling Motion Control, Image Animation and Avatar

Kling can animate a photo using a written motion description. You might request a slight head turn, movement in the background or a slow camera push-in.

For movement taken from an existing clip, Kling 3.0 Motion Control and 2.6 Motion Control transfer motion from video onto a photo. Pricing starts at 12.1 credits per second.

Kling 4.0 extends reference-video workflows by supporting camera movement, pacing and composition transfer with changes to the subject, product or background.

For talking portraits, Kling Avatar Standard and Pro take an image and audio as inputs and create an animated speaking photo.

Kling 4.0 vs. Kling 3.0: Which Model Should You Choose?

Kling 4.0 is designed for projects needing up to 30 seconds, native audio, reference-based generation or keyframe control.

Kling 3.0 supports up to 4K resolution, multi-shot generation with as many as five scenes and named elements using @name. It remains relevant when 4K output or a multi-scene structure matters.

Kling 2.6 provides video options with and without audio. Kling 2.5 Turbo Pro and 2.1 offer lower-cost options for shorter generations.

Choose Motion Control when transferring existing movement, or Avatar when animating a speaking portrait from supplied audio.

Kling AI Pricing on Neuromia

Generation costs depend on the model, video length, output resolution and source materials.

A 10-second Kling 4.0 video at 720p without input video costs 313.5 credits.

Input-video pricing works differently. The billable duration includes the generated video's length plus the applicable input-video duration, which is counted as at least the length of the generated clip. A lower per-second rate therefore does not automatically mean a lower total cost.

How to Generate Your First Kling AI Video

1. Open Neuromia and create an account.
2. Receive your free starter credits.
3. Choose Kling 4.0 or another available model.
4. Enter a prompt and upload any required images or references.
5. Select the available settings and check the credit cost.
6. Start the generation and review the completed video.

Rendering usually takes several minutes, with longer clips requiring more time. Starter credits can help you explore the platform, although they may not cover every selected configuration. Further usage is paid through the shared credit balance without a separate Kling subscription.

Kling AI is more than one video generator. The model family offers text-to-video, image animation, motion transfer, talking portraits and structured scene generation. Start with the creative task, then select the version that matches your preferred workflow and credit budget.
