Individual addressing of each LED cell in a pixel light such as the Astera Titan or ARRI SkyPanel, allowing software-driven animations, pixel effects, and practical simulations.
Definition
Pixel Mapping refers to the digital assignment of individual LED pixels to control signals. Each pixel receives individual RGB values and can be controlled separately.
Application in Practice
Pixel Mapping is used for:
- LED Panels: Control of large-scale video walls with individual pixel control
- Effect Lighting: Animation of running lights and color gradients
- Background Replacement: Dynamic backgrounds with precise color reproduction
- Practical Lights: Integration into set decoration with programmed light sequences
Technical Details
Technical specifications:
- Control via DMX512, Art-Net, or sACN protocol
- Resolutions from 16x16 to 4096x2160 pixels depending on panel size
- Color depth 8-bit to 16-bit per color channel
- Refresh rate 25Hz to 3840Hz for flicker-free recordings
Practical Tips
- Test and calibrate mapping software before shooting begins
- Create backup configuration files for all setups
- Synchronize camera frame rate with LED refresh rate
- Dimension power supply: Full load requires 60-80W per m²
Professional Standards
Standards for film production:
- CRI >95 and TLCI >95 for accurate color reproduction
- Genlock synchronization with camera shutter
- Color temperature adjustable from 2700K to 6500K
- DMX addressing according to USITT standard
