Physical Factors Affecting the Key
The quality of the key produced by Reality Keyer depends not only on the software’s internal adjustments but also on several physical factors related to the production setup. These factors include camera settings, cyclorama configuration, lighting, image resolution, lens characteristics, and more.
By carefully controlling physical factors, the quality of the keying process can be significantly improved, ensuring that the final matte is clean and precise. Each adjustment, from camera settings to lighting configurations, has a direct impact on the success of the key and the overall visual integrity of the virtual production.
Please follow:
📄️ Camera Settings
To achieve optimal keying results, it is crucial to adjust the camera settings appropriately, including manual iris control, disabling in-camera filters, avoiding overexposure, and utilizing features like CLASS for chromatic aberration correction.
📄️ Cyclorama Configuration
Proper cyclorama configuration, such as using professional chroma key paint, maintaining a larger width than depth, and ensuring even lighting with rounded corners, is essential for high-quality keying results.
📄️ Lighting Configuration
Lighting is one of the most critical factors in keying, as it directly influences the uniformity of the keying process. Proper lighting setup helps in achieving a clean and accurate key.
📄️ Image Resolution
Keying with high-resolution images improves the final result by ensuring more detailed mattes. While Reality Keyer can work with lower resolution inputs, keying at a higher resolution (e.g., 1080p for a 720p output) produces sharper results. After keying at the higher resolution, the image can be downscaled for output, resulting in better key quality with more fine details preserved.
📄️ Lens Effects
Managing lens effects, including minimizing lens flare with lens hoods and adjusting zoom levels to reduce vignetting, is crucial for achieving optimal keying performance.
