Someone starts the tape, walks away until the end of the film, returns to start the combination process, leaves again and returns to store the file. And with two SCSI external disks, a single G4 can be used to serve video. A 1 GB drive is minimum. Backing up data onto CDs is good. Dartmouth's entire video library is on CDs in a small bookcase.
Broad bandwidth is needed for video.
Dartmouth was entirely rewired two years ago. Wouldn't go with it again if starting over. Dartmouth is experimenting with Sorenson encoding in a QT container. One minute of playing time requires 30-35 min. of production time. Expect better, less costly technology in years to come.
