Talking points
10:40 Marshall Breeding, Vanderbilt, the classic example. Where does the incoming signal come from? About the digital capture setup, i.e., the workstation. What sort of worker does the capture work. About the archiving format: what were the considerations, what was the decision? About the quantity or rate of capture. About metadata (just a little!). About producing "access" copies. About the Web site. Who are users?

technology to the Archive’s work
About the quantity or rate of capture
Quality considerations included– File size vs video quality– Dealing with off-air capture, not studio quality– Aggressive data rate and resolution would not
lead to perceptible improvements in quality
