Hardware-based Versus Software-based Systems
Hardware-based systems (da Vinci 2K, Pandora, etc.) have historically offered better performance and a smaller feature set than software-based systems. The real time performance was optimised to particular resolution and bit depths unlike software platforms that use standard computer industry hardware and often trade speed for resolution independence. (i.e. Apple's Color (previously Silicon Color Final Touch), ASSIMILATE SCRATCH, Adobe SpeedGrade, SGO Mistika, etc.). While hardware-based systems always offer real-time performance, some software-based systems need to render as the complexity of the color grading increases. On the other hand, software-based systems tend to have more features such as spline-based windows/masks and advanced motion tracking.
The line between hardware and software is blurring as many software-based color correctors (e.g.Pablo, Mistika, SCRATCH, Autodesk Lustre, Nucoda Film Master and Filmlight Baselight) use multi processor workstations and a GPU (graphics processing unit) as a means of hardware acceleration. As well, some newer software-based systems use a cluster of multiple parallel GPUs on the one computer system to improve performance at the very high resolutions required for feature film grading. e.g. Blackmagic Designs DaVinci Resolve . Some color grading software like Synthetic Aperture's Color Finesse runs solely as a software based and will even run on low-end computer systems.

Famous quotes containing the word systems:
“The skylines lit up at dead of night, the air- conditioning systems cooling empty hotels in the desert and artificial light in the middle of the day all have something both demented and admirable about them. The mindless luxury of a rich civilization, and yet of a civilization perhaps as scared to see the lights go out as was the hunter in his primitive night.”
—Jean Baudrillard (b. 1929)
