Kling O1 Video Generator
Kling O1 is the industry's first unified multimodal video model launched by Kuaishou Kling AI in December 2025. Unlike traditional text-to-video models, Kling O1 adopts a revolutionary MVL (Multimodal Visual Language) architecture, breaking the boundaries between video generation and editing, allowing users to directly modify elements, lighting, or actions in existing videos through natural language conversation, without complex masks or post-production software. It not only generates high-quality videos but also solves the two major pain points of AI video: "character consistency" and "precise editing".

Kling O1 Core Features
Natural Language Video Editing (Video Inpainting & Editing)
This is Kling O1's most revolutionary feature. You don't need to use professional video editing software for frame-by-frame rotoscoping. Simply input text instructions, and the model can understand video content, precisely remove objects, replace backgrounds, or change the color of specific elements while perfectly preserving the video's original motion trajectories and lighting relationships.
Start & End Frame Control
Allows users to upload both a start image and an end image, and Kling O1 will automatically generate natural, smooth transition animations between these two frames. This is crucial for creating seamless scene transitions, object morphing, or connecting two different shots, greatly enhancing narrative coherence.
Multi-Subject Consistency
Solves the problem of "characters changing between shots" in AI videos. Kling O1 has a "director's memory" capability, understanding and remembering character or object features (such as faces, clothing, props) uploaded by users, maintaining highly consistent appearance across different shots and camera movements. Perfect for creating continuous short dramas or advertisements.
Video Style Repainting
While keeping the original video's structure, composition, and motion completely unchanged, render the entire video into a new artistic style through text prompts. Whether converting live-action footage to anime, or changing daytime scenes to cyberpunk nightscapes, it can be done with one click.
Motion Transfer
Extract motion patterns (such as camera movements or character actions) from a reference video and apply them to entirely new subjects or scenes. This means you can use a simple phone recording as "motion capture" material and have AI-generated high-quality characters perform exactly the same movements.

Frequently Asked Questions
Kling O1 is Kuaishou's first "unified multimodal" model. Unlike the 1.5/2.5 versions that focus on "generation from scratch", O1's core advantages are "editing" and "control". It can not only generate videos but also understand instructions to modify existing videos and maintain high character consistency across multiple shots.
Currently, Kling O1 supports generating 5-second or 10-second high-quality clips. Through the start & end frame control feature, you can seamlessly connect multiple clips to create longer content.
Yes. Kling O1 has powerful semantic understanding capabilities. You just need to say "replace that cat with a dog", and the model will automatically identify the cat's area and perform the replacement without manual frame-by-frame masking.
WeryAI provides daily free generation credits for registered users, allowing you to experience Kling O1's basic features for free. For watermark-free downloads, faster generation speeds, or commercial licenses, we recommend upgrading to Pro membership.
It's perfect for professional creations requiring fine control, such as: changing outfits for models in videos (e-commerce), fixing backgrounds with shooting errors (film post-production), creating serial short films with fixed character images (self-media), and creating smooth transition effects.
Yes. In "Video Editing" mode, you can upload MP4 or MOV video clips (recommended under 10 seconds), then use text instructions to repaint or partially modify them.
