That was all done using photoshop and FCP. The final result was a mix of the orginial footage masked together with a large number of still frames. By merging the two squences i could control the building’s lights while still having traffic moving. That spec was a test shoot in a way for a larger project i’m working on right now (i’m in the last night of production! we get to roll a car over!!!). I’m about to beginning that whole post process again. hope that helps. thanks for checking out my work.
