I think it's 'pored over' not doing enough work. I pictured him sitting there, very focused, watching the footage and thought, 'Oh, so he spent a week and a half on this'. But, thinking about it more, he's probably got to pay attention to each person for a whole viewing, replay anything worth including, figure out how to crop, zoom, and cut it together, and view drafts of the final product many times. No doubt he spent at least a thousand hours looking at that 60 hours.
