Almost everything you need to know about those Ross Acid Cameras.
ACID Cameras have been designed for maximum HD performance in any studio production environment. They offer best-in-class resolution, sensitivity and signal to noise ratio, plus unique UltrachromeHR outputs for chroma key applications.
While there are many camera choices available today, none address the fundamental quality problems that arise when combining live action capture within virtual environments. Standard HD video has bandwidth limited chroma content. When processing chroma keys for virtual environments, band limited chroma contains insufficient information to create a true high-resolution key signal from original content. As a result, chroma key edge quality is always band limited, as you simply cannot create edges with half the information ideally required.
