Editing - Time lapse

This is a video of some footage I collected from shooting at the NEC. The shot was filmed from a long shot and I deliberately did it from this range to do a time lapse to include in my documentary. I then edited the long shot footage I collected and speed up the footage at a different speed;

The first clip was speed up by x500 speed in which the clip was filmed for roughly about a minute which was then reduced to about 13 seconds. The second clip was speed up by x300 in which was filmed for about 30 seconds and reduced to 5 seconds.
