Iridas Releases SpeedGrade DI

Iridas announced the release of SpeedGrade DI. The new application offers an industry-leading feature set for digital color grading and film finishing. In addition, SpeedGrade DI anchors the industry's first complete color pipeline with SpeedGrade OnSet (look management) and FrameCycler (calibrated review with grading applied).

Users have praised the intuitive interface and efficiency of SpeedGrade DI.

"The user interface enhancements, automation features and simplification of operations have been great," said Mike Inchalik, vp of strategy and marketing with DTS Digital Images (formerly Lowry Digital Images). "With SpeedGrade, the color decisions are maintained as metadata and only applied at the end of the process. I can't overemphasize the savings that delivers."

"Already with the original SpeedGrade release in 2003, it was clear that our non-destructive approach had the potential to change the way color grading is done," said Lin Sebastian Kayser, ceo/founder of IRIDAS. "Rather than being the last link in the postproduction chain, we believed that the process of developing a film's look could be open, collaborative and iterative. Today with the release of SpeedGrade DI, the color pipeline is complete: the vision has been realized."
