real time vs. constructed time

In working with these clips I’ve begun to think about my use of footage as a medium. So understanding the act and duration of recording, whether it be for documentation or representation purposes.

I’ve been looking at Tarkovsky films, particularly his signature long takes which track between rooms, zoom or pan extensive landscapes or expose multiple occurrences, in real time within the one shot. He referred to this method as ‘sculpting in time’ as an affirmation of the materiality of the mediation.
Robert Bird, reiterates this emphasis on the medium and mediation of duration in Tarkovsky films in this paper.

I am also intrigued by his ability to actualise a kind of ‘extra dimensionality’- as described by David Haines, small metaphysical investigations which exceed a conventional understanding of time and space.
For example the levitating love making scene in Sacrifice - http://www.youtube.com/watch?v=2_aEjbYED0Q
and the final scene of Nostalgia - http://www.youtube.com/watch?v=RXYhLF2z_NM&feature=related
Perhaps these moments could be seen as realisation of the virtual?

I've also been jotting down some dialogue from the films

‘poetry in untranslatable like the whole of art…’
‘I’m a good translator. I even improve on the original’
‘where am I when I’m not in reality or in my imagination’
