The development of Colorfront Transkoder was inspired through collaboration with customers, including Technicolor in Hollywood, which has standardized its dailies services around Colorfront On-Set Dailies for motion picture and high-end TV customers.

"Technicolor has been a pioneer in digital cinema since its inception in 1999. We provide our clients with worldwide scale coupled with locally managed and delivered digital cinema releasing services including mastering and distribution. We’ve been extremely impressed with the speed and flexibility of Colorfront Transkoder for DCP and IMP creation. The team is sharp, fast and flexible and their products are a direct reflection of this."
