Kling AI
High-quality AI video generation by Kuaishou — clips up to 2 minutes with motion brush & lip sync
Kling AI is the AI video generation platform from Kuaishou Technology, one of China’s dominant short-video companies with hundreds of millions of users on its core app. Launched internationally in 2024, Kling AI immediately distinguished itself with a 2-minute native clip generation capability that no Western competitor matched. Beyond clip length, Kling offers motion brush for localized animation control, AI lip sync for portrait videos, cinematic camera path prompting, and a rapidly growing creative community hub. It is a full-featured platform aimed at serious video creators.
Visit Kling AIWhat is Kling AI?
Kling AI is the generative video product from Kuaishou Technology, the Beijing-based company that operates one of China’s two major short-video platforms alongside ByteDance’s Douyin. Kuaishou has invested heavily in AI infrastructure for its core consumer video product, and Kling AI represents the international commercialization of that research. The platform launched globally in mid-2024 and quickly attracted attention from filmmakers, animators, and content creators due to its ability to generate coherent video clips far longer than what competing tools offered at the time.
The defining technical achievement of Kling AI is its long-form generation capability. While most AI video tools cap native generation at 5 to 10 seconds, Kling can generate continuous clips up to 2 minutes (120 seconds) in a single pass. This is not simply a stitching operation — the model maintains temporal and visual consistency across the full clip length, which is technically demanding and rare. For creators building music videos, short film sequences, or extended product demos, this capability eliminates the manual work of seamlessly joining many short clips together.
Kling AI supports both text-to-video and image-to-video workflows. The image-to-video mode accepts a still image and a motion prompt, and the model animates the image while preserving subject identity and visual style. Motion brush adds a layer of creative control not found in most competitors: you paint directly on regions of the image to specify which elements should move and in what direction, giving you localized animation control that complements the broader text prompt. This is especially powerful for nature scenes, product shots with moving elements, and portrait animation.
The AI lip sync feature allows creators to synchronize a portrait video or image with an audio track, making it useful for dubbing, animated avatar content, and multilingual video localization. Combined with Kling’s cinematic camera path controls — where you describe panning, tilting, zooming, and orbital camera movements in plain language — the platform offers a comprehensive toolkit for creators who need more than basic generation. The Kling Creative Hub provides a community gallery of user-generated videos and associated prompts, making it a valuable resource for learning effective prompting techniques.
Key Features
2-Minute Native Generation
Generate coherent video clips up to 120 seconds long in a single pass. Maintain consistent characters, lighting, and visual style across the full sequence — rare in AI video tools.
Motion Brush
Paint directly on image regions to define localized motion direction and intensity. Animate specific elements like hair, water, or smoke while keeping other areas static.
AI Lip Sync
Synchronize any portrait image or video to an audio track. Useful for dubbing, avatar creation, and producing multilingual video content from a single base recording.
Cinematic Camera Control
Describe camera movements in natural language — dolly shots, orbital paths, tilt-ups, and zoom-ins — and Kling executes them with cinematic smoothness and compositional accuracy.
Image-to-Video
Animate any still image with a text motion prompt. Strong subject identity preservation means characters and objects remain recognizable throughout the animated sequence.
Creative Hub Community
Browse a growing gallery of community-generated videos with shared prompts. Learn effective prompting strategies from real examples and discover creative use cases.
Pricing
Kling AI uses a credit-based system. Free users receive daily credits that reset every 24 hours. Paid plans provide monthly credit pools at a significantly lower per-generation cost, with higher-tier plans unlocking the longest clip lengths and fastest queue access.
| Plan | Price | Credits/Month | Max Clip Length |
|---|---|---|---|
| Free | $0 | Daily credits (~66/day) | 5 seconds (standard quality) |
| Standard | $9.99 / mo | 660 credits | 10 seconds (high quality) |
| Pro | $29.99 / mo | 3,000 credits | 2 minutes (high quality) |
| Premier | $99.99 / mo | 8,000 credits | 2 minutes (priority queue) |
Credit costs vary by generation mode and quality setting. See klingai.com for the latest pricing and credit schedules.

Runway ML
Gen-3 Alpha generation with motion brush, inpainting, and a full creative editing suite. The professional standard for studios that need generation and editing in one platform.
Luma Dream Machine
Ray 2 model with excellent physics simulation and camera motion. 30 free generations per month and strong image-to-video support, though clips cap at 9 seconds.
Vidu
Shengshu Technology’s video generator with strong character consistency and 16-second HD clips. A solid alternative if you prioritize subject identity preservation.

Frequently Asked Questions
What is Kling AI?
Kling AI is an AI video generation platform developed by Kuaishou Technology, a major Chinese short-video company. It generates high-quality video clips from text prompts and images, with a maximum clip length of 2 minutes — the longest native generation available among mainstream AI video tools. Additional features include motion brush, AI lip sync, cinematic camera control, and a community creative hub.
Is Kling AI free?
Yes. Kling AI provides free daily credits that reset every 24 hours, allowing users to generate standard-quality videos without a paid subscription. Free clips are limited to 5 seconds and standard resolution. Paid plans starting at $9.99 per month provide monthly credit pools, longer clip lengths (up to 2 minutes on Pro and Premier), higher quality settings, and faster processing queue access.
How long can Kling AI videos be?
Kling AI supports native video generation up to 2 minutes (120 seconds) long. This is available on the Pro and Premier paid plans. Standard plan users can generate up to 10-second clips. Free users are limited to 5-second standard-quality clips. This 2-minute capability is Kling’s most distinctive feature — no other widely available AI video generator matches it for single-pass generation length.
What is motion brush in Kling AI?
Motion brush is a creative control tool that lets you paint over specific regions of an image to define where and how motion should occur in the generated video. For example, you can brush over a river to animate water flow while leaving the surrounding landscape static, or paint over a subject’s hair to create a wind effect. It provides localized animation control that goes well beyond what text prompts alone can specify.
Does Kling AI support lip sync?
Yes. Kling AI includes an AI lip sync feature that accepts a portrait image or video and an audio track, then generates a video where the subject’s lips are synchronized to the audio. This is useful for creating dubbed video content, AI avatar videos, and multilingual versions of video material without re-recording. The quality is competitive with dedicated lip sync tools for portrait-only use cases.
What are the best alternatives to Kling AI?
The best alternatives depend on what you need. Runway ML is the top choice if you need an integrated editing suite alongside generation. Luma Dream Machine produces some of the best physics and camera motion quality, though clips are limited to 9 seconds. Pika is faster and optimized for social media content. Vidu focuses on character identity consistency for portrait and character-driven videos. Kling remains the best option specifically when clip length is your primary requirement.
