The title of your etude
Video Controller
A short statement of intentions
I want to create a multible videostream controlled by a keyboard or bluetooth controller. This etude is connected to my Single Project.
What you initially wanted the piece to be about / for - its conceptionsHow you initially intend to create the etude
I wanted to use the Nintendo Wii controller to direct 9 videos on one screen through the Quartz Composer Application. But during the first steps of creating the batch I realized that a keyboard would work better as my Single project is an installation piece.
I want to place a manipulated keyboard (only a limited amount of keys are accessable) infront of a videowall. Through this keyboard the viewer is able to interact with the different videos that are shown. Change position and scale. It should have the feeling of beeing in a CCTV operating room.
Project explanaition:
THe videos show a room of a mental instituation - in which two inmates are trying to break out through dance. First they are in two seperate rooms but than they dance into one room. (they jump through a wall which will be shown with a simultanios cut on all video stream. The videostream are CCTV camera. 9 in total - attached to the celling of the room. In the end the inmates realize that they cannot break out through dance so they drop on the ground and start to breath heavily. In the end they day and escape through their breath.
Conceptualisation of the work / Reference
CCTV has become a medium of truth. It can even be used as evidence at court. I want to play with this truth. To present a totally staged and even cut film as if it happens now as if it is this new truth! This is the frame of my idea. Dance and especially contemporary dance, is in my mind a brilliant from of expression, which hasn’t been, explored much in installations and is definitely “new” to CCTV art.
CCTV art:
From the Cambridge News Webpage:
(1) BIG Brother-style surveillance cameras could be installed around Cambridge as part of a controversial art project.Artist James Coupe wants to put up the cameras to catch memorable moments from people's everyday lives, and aims to produce feature films from the footage, to be shown at an international film festival.His plan is to place between eight and 12 cameras around the city to capture public activities including greeting kisses, farewell scenes, and meetings.
Banksy CCTV ART
Banksy has been an influence in my approach of street art. His various museum visits (including the Louvre, Tate Modern and museum of contemporary art NY) set a whole new league to art piracy.

This museum piece place the presents of CCTV in a context of preservation. As old oil paintings seam to be a preservation of past time. Will CCTV be preserved as a past way of lifing one day. This is also a strong statement of the current presents of CCTV world wide. (especially in the UK were 35% of all public CCTV cameras are installed)
Abuse of the Public Domain by UK artist Stanza.
(3) This exhibition features large-scale projections of 2 works, which use live real-time data from CCTV cameras cited in two cities, London and New York . Security tracking data is Stanza's chosen medium for these process led artworks.
Images taken from the Stanza exhibition, 'You are my subjects'. YOU ARE MY SUBJECTS uses data from a single fixed cctv camera in NYC, focusing on subjects as they pass below it.
Multiple cameras are accessed randomly in real time to make an urban tapestry. What you see is an evolving, generative artwork. These images are from taken London, and they happen as you see them, in real time. The installation versions of this work can be presented in art galleries using projectors or plasma displays. This online artwork represents many realities that exist in city space. The observed real time surveillance society is re worked into a series of grids. This presents London to a global online audience. The data that you see is protected by the data protection act. Here it is re mixed into what you see, which is this online artwork that look like a filmic experience.
This England: A Green and Pleasant Land 2005. - Live Now.
another CCTV project by Stanza
(4)Sublime paintings in the "northern romantic tradition". These pastoral landscapes and seascapes are real time paintings. Instead of CCTV watching our movement in urban space these cameras point out to the landcape or towards the sea. Typically this subject matter was the focus of the 'Old Masters'.
In 'Sublime: This England' .I create a morphing series of real time paintings that are always changing. Please note this is not a film but a generative experience of the landscape.
EXTRA WORK. Emergent world. Using thousands of camera view live plus thousands of sounds. A perspective of the world in real time.
Describe and depict what the actual concept of the etude is.
Write about:
THe porpuse is to recreate a CCTV ooperation room. Thorugh the process of programing I am going to learn more about Quartz composer and how to feed this application with life informatoin which than reacts to a virtual infornmant. The spectator of the installation will feel closer/more involved in the actual film that is shown on the videowall it will be more belivable that this is actually happen now and that it is a CCTV recording.

Technical Analysis
---------------------------------------------------first attempt
Image 1: creating a background through black image and billboard (replaced it later with clear)
Image 2: importetd differnet movei files and positioned the sprites on the screen
Image 3: in total 9 files and 9 sprites (they represent the CCTV stream/files I will use later on )
Image 4: I copy and pasted all the files/sprites and added a keyboard controll to the pasted sprites (it is enabled until I press (in this case "q" - when pressed it will play the file in full screen mode
Image 5: at first I had a problem with the pasted sprites when they were unabled but than I understood how to put layers in the background
Image 6: changing inspector in sprites for full screen mode
Image 7: a bit of a mass to many files (figured out later how to creat a nice hierachy
Image 8:all 9 files palying at once
----------------------------------------after little chat with Ian and his explanaition of q c
Image 9: I wanted to use uncompressed files instead of quicktime compressed ones so I exported a file with different filters as dv (uncompressed)
Image 10: changing hierachy
Image 11: changing hierachy in root folder
Image 12: using uncompressed files didn't change anything .. even lower framrate and 98% rendering load .. so I went back to my compressed ones.
Image 13: I tryed to work out how to change the position of two sprites when pressing a button through keyboard control.. but it didn't work ... tryed all kinds of tools and controllers but couldn't figer it out....
---------------------------------------wrote Ian an email..
Ian emeiled me promptly some patches and solutions
Image 14: I imported the swop patch and tryed to figure Ians explanation out - which seamed to be written in japanies with roman letter.... but I after all not that difficult ..... I erased the Image Dimensions . didn't need that
Image 15: changed teh java script for the first swop on a X position
Image 16: did the same with to other video on a Y position
Image 17: and finaly created another output to change three positions at once.....
--------------------------------------what else could I ad???
Write about:
THe first and main problem was that I never used Quartz Composer before so I had no idea where to start. I analized a couble of batches which I downloaded from the apple side. And simply played around with the programm. At one point I thought I understood how I can controll the videos. This inlightment came upon me while drinking tea from my new tea lamp!!!
How successful is the etude?
It works perfect. All I need now is a faster mac for the final performance. But as a etude it works perfect.
