How to Use Move AI

Move AI has revolutionized motion capture technology with its markerless solutions, making high-quality 3D motion data accessible to creators of all levels. This guide will walk you through the process of using Move AI’s primary products: Move One and Move Multi-Cam, providing you with the knowledge to integrate this powerful tool into your creative workflow.

How to Use Move AI

Move One is Move AI’s solution for single-camera motion capture, ideal for individual creators and small teams working in limited spaces. Here’s how to use it:

1. Download and Install the App
   • Visit the App Store and download the Move One app.
   • Ensure your device is compatible: iPhone 8 or newer, running iOS 16 or above.
2. Set Up Your Capture Space
   • Choose a well-lit area free from obstructions.
   • Clear a space up to 5m x 5m for optimal results.
   • Ensure good, even lighting to enhance capture accuracy.
3. Position Your iPhone
   • Set up your iPhone to cover the entire performance area.
   • Use a tripod or stable surface to minimize camera shake.
   • Experiment with camera angles to capture the best view of the performance.
4. Capture the Performance
   • Open the Move One app and start a new recording session.
   • Choose between portrait or landscape mode based on your needs.
   • Record takes up to 60 seconds in length.
   • Perform the desired motions clearly and deliberately.
5. Process and Export Data
   • After recording, the app will process the video to extract motion data.
   • This typically takes a few minutes, depending on the length of the recording.
   • Once processed, export the data in FBX or USD format.
6. Edit and Integrate
   • Import the exported motion data into your preferred 3D animation software.
   • Apply the motion to your 3D character rig.
   • Fine-tune the animation as needed to fit your project requirements.

Move Multi-Cam: Advanced Multi-Camera Motion Capture

For more complex projects or larger capture volumes, Move Multi-Cam offers a powerful solution. Here’s how to utilize this advanced system:

1. Camera Selection and Setup
   • Choose compatible cameras: GoPro, Sony, Blackmagic, or iPhones.
   • Set up multiple cameras around your capture area (up to 20m x 20m).
   • Ensure cameras are positioned to capture all angles of the performance.
   • Synchronize cameras for accurate data capture.
2. Calibration
   • Follow the Move AI calibration process carefully.
   • Use calibration tools provided by Move AI to ensure proper alignment.
   • This step is crucial for accurate motion data extraction.
3. Capture the Performance
   • Record the performance using all cameras simultaneously.
   • Move Multi-Cam can capture up to 22 people at once.
   • Ensure performers stay within the designated capture area.
4. Upload and Process Videos
   • Upload the recorded videos to the Move AI platform.
   • The system will use AI and computer vision to convert 2D video into 3D motion data.
   • Processing time will vary based on the length and complexity of the capture.
5. Export and Use Data
   • Once processed, export the motion data in FBX or USD format.
   • The data can be retargeted to custom character rigs in your 3D animation software.
   • For complex scenes, you may need to process data for each performer separately.

Best Practices for Using Move AI

To get the most out of Move AI, consider these best practices:

1. Lighting
   • Use consistent, bright lighting to ensure clear video capture.
   • Avoid harsh shadows or overly bright spots that may interfere with motion tracking.
2. Clothing and Accessories
   • While Move AI doesn’t require special suits, avoid loose or flowing clothing.
   • Remove accessories that might obscure body movements.
3. Performance Space
   • Keep the capture area clear of obstacles and unnecessary objects.
   • Mark the boundaries of the capture space to guide performers.
4. Camera Positioning
   • For Move Multi-Cam, ensure cameras have overlapping fields of view.
   • Test different camera heights and angles to capture all necessary movements.
5. Rehearsal and Testing
   • Conduct test captures before your main performance.
   • This allows you to identify and resolve any issues with setup or performance.
6. Data Management
   • Organize your captures with clear naming conventions.
   • Back up your raw video files and processed motion data regularly.
7. Software Updates
   • Keep the Move AI app and any associated software up to date.
   • Updates often include performance improvements and new features.

Integrating Move AI into Your Workflow

1. Pre-production
   • Plan your motion capture sessions in advance.
   • Storyboard or create animatics to guide your capture process.
   • Prepare your 3D character rigs to receive the motion data.
2. Production
   • Capture your performances using Move One or Move Multi-Cam.
   • For complex scenes, break them down into manageable segments.
   • Take multiple takes to ensure you have the best possible performance.
3. Post-production
   • Import the motion data into your 3D animation software.
   • Clean up and refine the captured motion as needed.
   • Blend different takes or add additional animation to enhance the final result.

Troubleshooting Common Issues

1. Poor Data Quality
   • Check lighting conditions and camera positioning.
   • Ensure performers are wearing suitable clothing.
   • Recalibrate your setup if using Move Multi-Cam.
2. Processing Errors
   • Verify that your video files are in a compatible format.
   • Check your internet connection for cloud-based processing.
   • Contact Move AI support for persistent issues.
3. Export Problems
   • Ensure you have the latest version of the Move AI software.
   • Check that your 3D software is compatible with the exported file format.

Pricing and Plans

Move AI offers flexible pricing to accommodate different user needs:

• Move One: Plans start at $15/month, suitable for capturing single subjects in small spaces.
• Move Multi-Cam: Custom pricing based on factors like the number of people, capture volume, and processing minutes. Indie and creator pricing plans are available.

Consider your project requirements and budget when choosing a plan. Move AI also offers custom enterprise solutions for larger studios or more complex needs.
