Building Construction.2

Actual Elapsed Time: 2.8 hours (10,000 seconds)

Several new girders are added to the new San Francisco library building. By speeding up the action 1,000 times normal speed, we can view the progress being made. First, several girders are attached to the growing structure. Then, the crane lifts more girders from the ground to a temporary storage area on the top floor. The crane then goes about adding girders again.

How This Clip Was Made:

This time-lapse video was created by shooting 2.8 hours of regular video. Only 1 of every 1,000 frames of video was digitized and transferred to a computer. When displayed, the remaining frames show the action at 1,000 times normal speed. Production: David Schwabbe, San Francisco Public Library. Post-Production: Jeff Fohl.
