Is most of the audio ADR looped?
Maybe its the data compression codec playing over the web but the audio seems a little off sync and too much on-mic.
The audio on the streaming version is off a tad bit caused by the encoding process, I believe the ipod version also suffers from similar audio-sync issues. The 360p and 720p versions both should be just fine.
Star Trek: Phoenix was ADR'd, the entire audio was completely replaced, there is no original production sound which was used in this project.
