They do not run the parade straight through as you would vision. What they do is they start very early in the AM and bring one float out at a time. They will bring that float out to Main Street and film it coming down Main Street over and over again. Backing it up bringing it forward, repeat, repeat...until they get the perfect shot. Then that float will leave and about 10 minutes later another float will be brought out. It literally takes all day (sometimes 2 days) to film everything.
