00:00:21.000 --> 00:00:30.000  
The most recent form of image sequences we can find on the internet in vast numbers are time lapses. 

00:00:31.000 --> 00:00:35.000 
They bring us some spectacular visual experiences.

00:00:35.800 --> 00:00:44.000
But spectacularity itself fades fast if it is not followed by more substantial context.

00:01:17.000 --> 00:01:26.000
In this clip from Gustavo Tarretto's film we see a images of buildings in a big city.

00:01:27.000 --> 00:01:32.000
They are being put in context by a voiceover comment.

00:03:51.000 --> 00:04:05.000
Let us now take a look at a longer sequence from a documentary that uses time lapse in a very engaged context to convey certain ideas.

00:04:22.000 --> 00:04:35.000
Koyaanisqatsi is entirely made of visually stunning footage by Ron Fricke and equally masterfull continuous music by Philip Glass. 

00:04:36.000 --> 00:04:44.000
Note how timelapses and slowmotions are used to underline the conveyed message.

00:06:54.000 --> 00:07:11.000
Also note the use of long focal lenght lenses to shorten the perspective and make people moving through the bussy streets in slow motin appear even more out of breathing space.

00:09:01.000 --> 00:09:15.000
The short focal lenght and camera movement at the end of the sequence accent the thretening destructive power of a sofisticated man operated weapon.

00:09:26.000 --> 00:09:32.000
In order to achieve the desired cinematic effect, a careful planning is required.

00:09:33.000 --> 00:09:43.000
This is a very complex scheme of camera positioning for a scene from Alfred Hitchkock's North by North-West.

00:09:45.000 --> 00:09:48.000
Let's see the whole scene put together.

00:14:04.000 --> 00:14:16.000
After we have seen the scene itself, let us now hear the author explain his thoughts and the plan behind this scene.
