Agriculture: Agricultural activities over the course of the year (video recording)

Agriculture: agricultural activities in the course of a year. (At 4 minutes and 50 seconds, the speaker hesitates: this is because the person who was doing the filming was gesturing to indicate that there was a technical problem with the video. At 6 minutes and 24 seconds, attempts at recording with the faulty camera stop; the interviewers briefly talk to each other; the consultant pauses briefly, then resumes.) This document has two corresponding video files: a three-quarters view of the face, and a front view. Due to a technical problem, the video signal for the three-quarter view is missing as from 6 minutes 30 seconds; the video signal from the other camera was therefore duplicated from 6'30'' so as to yield a complete video document. There are five audio signals in total: one from a head-mounted microphone (omnidirectional SENNHEISER HSP2), one from a 'common' microphone (AKG C900), one from a professional microphone (AKG C414 XLII), and one from each of the two video cameras. The first three microphones can be seen in the front view video.
