T3 - 7.1 MIXES FOR BLU-RAY AND HD DVD: WORKFLOW FROM MIX TO ENCODE
Presenters:
Ronny Katz, DTS, Inc.
Jeff Levison, DTS, Inc. Consultant/Levison Audio
Abstract:
With the advent of Blu-ray and HD DVD discs on the market, consumers can enjoy up to 8 channels of surround audio. For example, there can be more than the usual two surround channels, or additional loudspeakers for height information can be added. Theatrical movie presentation is just beginning to evolve to take advantage of these new loudspeaker locations, and few re-recording stages are fully implemented to mix in these new configurations. To meet the demand for 7.1 audio for the new optical disc formats, new approaches to original production and remixing techniques will be needed. Jeff Levison will walk you through a variety of strategies for both music and film. Musical approaches from in-studio productions to live recordings will be presented.
As movies are released in these new formats, remixing 5.1 releases to create new 7.1 versions is inevitable. A film mix from 5.1 stems will be used to evaluate decisions for making a new 7.1 mix and the final version compared to the original 5.1 mix. Using this 7.1 master, Ronny Katz will review the workflow of audio encoding for next-generation formats, including PCM audio preparation, surround channel layouts, interactive secondary/sub audio, a bit budgeting overview, and quality control. The tutorial will include a demonstration of audio quality control and discuss relevant topics such as batch encoding, bit-rate analysis for lossless audio, and bit-stream editing.
