KlingAI O1: The World's First Unified Multimodal Video Model - How to Use It in Artflo
The fragmentation of AI video creation is over.
On December 1, 2025, the KlingAI O1 model was officially released, marking a historic shift in the field of video generation. For the first time, a single unified model integrates text-to-video, image-to-video, video in-painting (adding/removing objects), style transfer, and shot extension.
No more jumping between multiple tools or mismatched workflows. With KlingAI O1, you can go from a spark of inspiration to a fully edited, polished video in one seamless stop.
What Are the Breakthroughs in KlingAI O1?
Multi-Modal Input: The "All-Seeing" Editor
Relying on deep semantic understanding, KlingAI O1 treats everything-images, videos, specific subjects, and text-as executable instructions. It shatters the boundaries between modalities. Whether you upload a photo, a video clip, or a character sheet, the model comprehensively understands your intent to generate precise video details.
Solving the "Consistency" Problem
KlingAI O1 rebuilds the very foundation of video consistency by reinforcing its deep understanding of input images, effectively acting like a human director to maintain continuity. When you upload a character reference or subject chart, the model anchors the identity, props, and clothing details, ensuring they remain stable across different shots. This means that no matter how the camera pans, zooms, or rotates, your protagonist remains instantly recognizable without the morphing issues of the past, finally delivering the industrial-grade consistency needed for professional storytelling.
Multi-Reference
Just like image models such as Nano Banana Pro and FLUX.2, KlingAI O1 brings multi-subject fusion to video. You can freely combine up to 7 different reference images-mixing characters, props, and styles. Even if the scene atmosphere changes drastically, KlingAI O1 ensures that every "protagonist" maintains their unique features across different shots.
Parallel Multi-Tasking
Why do one thing when you can do two? KlingAI O1 supports composite tasks.
- Example: "Add a new character to the video AND change the background style simultaneously."
- Example: "Generate a video from a reference image AND apply a claymation filter."
This significantly reduces the complexity and cost of the creative process.
Flexible 3-10s Narrative Generation
Every shot needs its own breathing room. Instead of fixed durations, KlingAI O1 supports free generation between 3 to 10 seconds. Whether you need a quick, punchy visual impact or a slow, atmospheric establishing shot, you control the pacing of your narrative.
KlingAI O1 Capabilities: A Deep Dive Test
Image & Subject Reference
The Capability: KlingAI O1 allows you to upload 1 to 7 reference images simultaneously.
The Workflow: Define interactions between characters, props, costumes, and scenes using text. Watch as static elements from your photos come alive, interacting naturally within the generated video.
Video In-Painting: Add Content
The Capability: Insert new objects into an existing video seamlessly.
The Workflow: Simply mask an area in your video and type a prompt like "Add a vintage car driving by" or "Place a vase of flowers on the table." The model calculates lighting and perspective to ensure the new object fits perfectly into the original scene.
Video In-Painting: Remove Content
The Capability: The ultimate "Magic Eraser" for video.
The Workflow: Remove unwanted passersby, watermarks, or clutter from a shot. KlingAI O1 intelligently fills the void with background textures that match the surrounding environment in motion, leaving no trace behind.
Switch Perspective & Camera Angles
The Capability: "Re-shoot" a scene without a camera.
The Workflow: Take an existing flat shot and transform it. Use prompts to change the camera angle (e.g., "Switch to a low-angle view" or "Zoom out to a drone shot"). The model reconstructs the 3D geometry of the scene to generate the new perspective while keeping the subject consistent.
Video Modification
KlingAI O1 offers granular control over every element of your video:
Modify Subject: Change a person's clothes or swap a dog for a cat while keeping the motion.
Modify Background: Transport your subject from a bedroom to a cyber-punk city.
Modify Style: Turn a realistic video into an anime, oil painting, or claymation style.
Modify Color: Change a red sports car to neon blue.
Modify Weather: Turn a sunny day into a thunderstorm.
Green Screen: Automatically remove backgrounds for VFX workflows.
VFX Play: Add flames to a sword, freeze the environment, add facial tattoos, or apply a "red-eye" horror effect.
Context Generation (Prequel & Sequel)
The Capability: Extend your story in both directions.
The Workflow: Upload a 3-10s video clip. You can ask the model to generate what happened before (Prequel) or what happens after (Sequel). By combining this with text or image prompts, you can build a coherent timeline shot by shot.
Camera Movement & Motion Reference
The Capability: Steal the "move," not just the look.
The Workflow: Upload a reference video that has a specific camera movement (e.g., a complex dolly zoom or a whip pan). KlingAI O1 extracts only the camera trajectory and motion dynamics, applying them to your new subject and scene. This allows you to replicate professional cinematic techniques instantly.
