AB  - A persistent challenge with enabling remote collaboration for cinema post-production is synchronizing audio and video assets. This paper details efforts to guarantee that the sound quality and audio-video synchronization over networked collaborative systems will be measurably the same as that experienced in a traditional facility. This includes establishing a common word-clock source for all digital audio devices on the network, extending transport control and time code to all audio and video assets, adjusting latencies to ensure sample-accurate mixing between remote audio sources, and locking audio and video playback to within quarter-frame accuracy. We will detail our instantiation of these techniques at a demonstration given in December 2009 involving collaboration between a film editor in San Diego and a sound designer in Marin County, California.
