Marin County, California (June 13, 2000) - Sonic Solutions announced today that Henninger Video has expanded their DVD production capabilities with new systems and technology from Sonic. In addition to growing DVD production capabilities at its Arlington headquarters, Henninger is capitalizing on the burgeoning DVD-Video and DVD-ROM market in Nashville by expanding its services with the addition of DVD Creator at the Henninger Elite Post facility located there. The new systems, based around Sonic's next-generation SD-2000 MPEG-2 encoder, will be utilized for high-end commercial production and feature film DVD encoding and authoring.

"We are in awe of the quality of the new Sonic SD-2000 encoder," said Kurt Walther, project engineer at Henninger Interactive Media in Arlington. "It beats out MPEG-2 encoders costing three times as much, yet comes with unique functionality like Direct-24P video encoding from 24P masters and direct integration with Sonic DVD authoring applications. We are enthusiastically building our DVD business with Sonic technology."

"We are extremely pleased to add a full line of DVD services using Sonic DVD Creator, including DVD-ROM and web-enabled eDVD(tm) technology to our Nashville facilities," said Jason Wood, manager of Henninger Interactive at Henninger Elite Post.

"We are very pleased that Henninger selected Sonic DVD Creator to double their DVD production capacity," said Giles Baker, Product Manager for DVD Creator at Sonic. "Sonic's new SD-2000 encoder represents the culmination of years of development and delivers what we believe to be the highest-quality MPEG video yet seen - initial customer feedback has been nothing short of phenomenal."

• Constant-Q(tm) VBR - Sonic's patented technology for maximum quality video encoding, regardless of the quality of the video source material
• AutoCadence(tm) IVT - For removing 3/2 cadence from film-sources content, AutoCadence guarantees 100% accurate field removal for a 20% improvement in video quality
• Pre-Encoding Optimization - Integrated video pre-processing eliminates high-frequency noise prior to MPEG encoding - maximizing picture quality and delivering the most film-like MPEG video to date

A single PCI card, the SD-2000 encoder includes SDI digital video I/O, multi-channel digital audio I/O and integrated RS-422 machine control and linear timecode reading.
