Plask.ai - AI-powered motion capture that transforms any video into professional 3D animation

What is Plask.ai

If you've ever tried creating professional 3D animation, you know the frustration: traditional motion capture requires expensive equipment, specialized studios, and technical expertise that puts it out of reach for most creators. That's exactly the problem Plask.ai was built to solve.

Plask.ai is an AI-powered web-based motion capture platform that transforms any video into professional-grade 3D animation—right in your browser. No downloads, no installations, no expensive hardware. Just upload your video, and Plask's AI algorithms analyze the movement and generate accurate 3D skeletal animations that you can export directly to your preferred 3D software.

What makes Plask.ai stand out is its accessibility without compromising quality. The platform supports full body and hand capture, multi-person tracking, and exports to industry-standard formats including FBX, GLB, BVH, and VMD. Whether you're working with Unreal Engine, Blender, Unity, After Effects, Metahuman, VRoid, or Ready Player Me, Plask.ai integrates seamlessly with your existing workflow.

The platform has earned trust from major industry players. Companies like Nexon (one of Korea's largest game publishers), Square Enix (creators of the Final Fantasy series), Activision (Call of Duty), and Warner Bros have used Plask.ai for their projects. Academic institutions including the University of Tokyo have also adopted the technology for motion analysis research.

Core Features of Plask.ai

Plask.ai offers a comprehensive suite of tools designed to make professional motion capture accessible to everyone. Here's what you can accomplish with the platform:

AI Motion Capture is the heart of Plask.ai. Upload any video—cell phone footage, screen recordings, or professional shots—and the AI analyzes human poses frame by frame, converting 2D movement into precise 3D skeletal animations. This opens up possibilities that were previously reserved for studios with massive budgets.

Full Body & Hand Capture goes beyond basic body tracking. Plask.ai separately models body and hand movements, giving you accurate finger animations that are essential for gestures, sign language, musical performances, and other detailed work. Many motion capture solutions skip hand tracking entirely, but Plask delivers the nuance you need.

Multi-person Capture handles complex scenes with multiple actors. Whether you're capturing a dance routine, martial arts sequence, or game cutscene with several characters, Plask.ai tracks and separates each individual, assigning the correct skeletal animation to each character.

When it's time to bring your animations into your production pipeline, Multi-format Export has you covered. Export to FBX for Unreal Engine and Unity, GLB for web and AR applications, BVH for legacy software and motion analysis, or VMD for MikuMikuDance and Japanese animation workflows.

Real-time Collaboration lets team members work on the same scene simultaneously. Powered by WebSocket technology, changes sync instantly across all connected clients—essential for distributed teams and agency workflows.

Video Rendering & Scene Sharing provides built-in rendering tools and shareable scene URLs. Quickly preview your animations or send a link to clients for approval without them needing to install any software.

Auto Camera & Lighting uses AI-assisted scene setup to automatically configure camera angles and lighting. This gets you to a usable 3D environment faster, though you can always fine-tune manually.

Customizable Effects allows you to add visual overlays and adjust post-processing parameters to match your project's branding or artistic direction.

Who Is Using Plask.ai

Plask.ai serves a diverse range of creators, from solo indie developers to major studios. Here's how different users leverage the platform:

Game Developers traditionally face a significant bottleneck: professional motion capture costs thousands of dollars per minute and requires booking studio time. With Plask.ai, developers upload their reference videos and generate character animations in minutes. This dramatically reduces both cost and production time, enabling smaller studios to compete with larger teams on animation quality.

Indie Developers and Hobbyists often lack both the budget for professional motion capture and the expertise to animate manually. Plask.ai democratizes 3D animation—anyone can create professional-quality movements without years of training or expensive equipment. This is transformative for solo game developers, modders, and creators just starting their 3D journey.

3D Artists and Animation Studios use Plask.ai to streamline specific workflows. Japanese creators particularly appreciate the VMD export for MikuMikuDance (MMD) productions—a traditionally complex process now simplified to just uploading a dance video. Studios report that Plask.ai accelerates pre-visualization and helps them iterate on animation concepts faster.

Short Video and TikTok Creators have discovered a unique advantage: Plask offers 24-hour custom animation services, enabling content creators to produce viral 3D content at scale. The speed-to-market advantage is significant in fast-paced social media environments.

Academic Researchers benefit from accessible motion analysis. The University of Tokyo and other research institutions use Plask.ai to analyze human movement from video footage—no specialized motion capture hardware required. This opens up motion study possibilities for researchers without access to lab-grade equipment.

Pricing Plans

Plask.ai offers three tiers designed to match different user needs—from casual experimentation to professional production workflows.

Free Plan — $0/month

Perfect for exploring the platform and trying out basic motion capture projects. Includes 15 seconds of capture per day, 1GB of storage, and access to all core features: full body and hand capture, multi-person tracking, FBX/GLB/BVH export, video rendering, scene sharing, and real-time collaboration.

Standard Plan — $18/month

Ideal for regular users and indie developers with consistent motion capture needs. Provides 10 minutes of capture per month (compared to the free tier's ~7.5 minutes weekly), 3GB of storage, and faster processing speeds. The increased storage means you can keep more projects organized without cleanup.

Pro Plan — $50/month

Designed for studios and professional teams with high-volume requirements. Offers 1 hour of capture per month, 10GB of storage, the fastest processing speeds, early access to new features, and team organization tools. This plan also includes priority support for faster issue resolution.

All paid plans include faster processing than the free tier—a meaningful advantage when you're iterating on animations and need quick turnaround times.

Getting Started

One of Plask.ai's biggest advantages is how quickly you can begin using it. There's nothing to download or install—everything happens in your browser.

Step 1: Access the Platform

Visit https://plask.ai in your web browser. Plask.ai works best in Chrome for the optimal experience, though it also supports Edge, Firefox, and Safari.

Step 2: Create Your Account

Sign up using your email address or connect through your social media accounts. The registration process takes less than a minute.

Step 3: Upload Your Video

Click the upload button and select your video file. For the best results, use footage where the subject is clearly visible, the background is uncluttered, and lighting is adequate. The subject should be fully in frame with no major obstructions.

Step 4: AI Processing

Once uploaded, Plask.ai's algorithms analyze the video and generate the 3D animation automatically. Processing time depends on video length and complexity—typically a few minutes for short clips.

Step 5: Review and Export

Preview the generated animation. If needed, you can adjust parameters or review specific frames. When satisfied, export to your preferred format and integrate it into your project.
