Art captures a moment the way an artist sees it- artists are rooted in their time and their creativity reflects a view of the world. Time itself just flows, but art helps create a structure of points in time- think of the chronology of many great art museums. Framing refers both to the physical frame of the picture and means how you look at or understand a situation- like the old saying about whether you see a glass as half full or half empty, you can turn something negative into a positive experience. Art speaks metaphorically.
(At least, I think she's saying something along these lines)
