T5 - Lipsync in the Latency Age
Presenter:
Friedrich Gierlinger, IRT Munich
Abstract:
Synchronization of audio and video through the whole broadcast chain became ever more challenging with the switch to fully digital production methods, wireless picture acquisition practices, omnipresent different processing latency, and an unavoidable delay in consumer displays that may or may not be able to be compensated. This tutorial examines systematically examines the various reasons why lipsync problems occur, quantifies the possible error at any given stage, and recommends best practices to improve the situation.
