In this video I demonstrate the field recorder workflow in Pro Tools HD. Usually a video editor will cut a sequence together using a rough mix from an audio field recorder. This is generally a blend of the various mics which has been done in real time by the sound recordist at the time of shooting. At the same time the microphones will also be recorded to their own isolated tracks on the recorder. Using the embedded metadata and timecode from the BWAV files Pro Tools is able to rebuild the multi channel recordings, expanding the various microphone channels to new tracks in Pro Tools and matching the edits made by the video editor. This involves designating a track as a field recorder guide track and then using Field Recorder Match Criteria to specifiy to Pro Tools what consistutes a match to the edited rough mix. An overview of this process can be seen here.
