Silicon Grail was founded by Oscar winning special-effects specialist Ray Feeney in 1995, MacCentral reports.
Upon its introduction, Chalice was the first commercially available high-end 2D film-compositing solution. RAYZ is also a compositor, based on Chalice. This solution offers special effects and colour-correction tools for cinema, and was used in the production of Men In Black.
Apple's purchase of Silicon Grail follows its release of the HD (high-definition) Cinema Display and its acquisition of high-end rendering and compositing specialist Nothing Real.
An Apple spokesperson told MacCentral that Apple "plans to use Silicon Grail's technologies in future products".
