2nd-5th March 2005
7th floor project room
Leader: Amanda Steggell
BA3 and MA students and Maria!
Participants: Camilla, Kristine, Kaia, Mattias, Maria and Anne Liis.
This worklab investigates the use of the potentially “seamless” distribution of multi channel video from one computer across a maximum of three video screens (projectors and/or monitors), and the composition of video in physical space. The worklab is aimed at people who have projects/ideas they wish to realise that involve the composition of multi channel video in physical space, and with video material to experiment with. Live video is also an option.
The ideas of each participant will be treated as case studies in which all participants will work as a team to help test out – practically and conceptually. Therefore, if you sign up for the worklab you must be prepared to share your knowledge and skills, and see it through to the end.
The main software tool used in the workshop will be HC Gilje’s VPT: Video Projection Tools v.4.1 (unless he releases another version!), which, as HC writes on his web page, are “built using maxmsp+jitter, and are primarily intended for people who don´t have these applications. They work both for mac osx and windows xp”.
You can find out about-, and download VPT 4.1
We also use Matrox graphics expansion modules Dual- and TrippleHead2Go
DAY 1: Serious play
On day 1 Amanda gave an introduction via a case study of her first and only experience of using HC’s VPT in Verk Production’s Play Alter Native by Finn Iunker. She describes the collaboration of video, stage lighting and action on stage, and the changes that took place during the collaborative process that led towards the production.
Props where used (a plate, a bread board, etc) during the presentation to draw video elements out of the flat wall and into the space. Here video layers/objects were rescaled and some basic dramatic potentials/elements that included physical actions where demonstrated. Lastly she picked out the horizontal motion of simple graphic elements (rockets) that moved on a horizontal axis across 3 screens as something she would like to explore further. The 3 screens, originally aligned together, were split up;
- 2 projectors on one wall – one projector horizontal, the other vertical with approx 1m in between.
- 1 projector on the adjacent wall placed horizontally.
Interesting to see how the speed of transitions through space affected perceptions of continuous flow. Slowing down the video layers to almost half their original speed became an optimal solution for the perceptional erasing of the gap between the movement and the actual gaps between the projections.
We also looked at how 3 projectors of the same age, make an model produced different colour/contrast/luminance results, even when on identical settings and how shadows functioned in the divisions between the 3 adjacently, (almost) seamlessly placed video projections/projectors.
After lunch Kristine brought some footage from her project that takes its point of departure from a research into the practice of dubbing and the dubbing industry. Much fun was had manipulating two videos of talking heads, speaking interlocking monologues, directed and written by Kristine herself in the style of Samuel Beckett. Technically speaking, serious play led to demos of masking video, slowing down and speeding up video/voice compositing video images on top of each other, using corner pin manipulations, how to store presets and make cue lists.
We discussed the issue of resolution of image when using real time processing tools …. what you win and what you lose, and how all hard- and software plays its role.
Mattias provided an extra pedagogical layer by demonstrating the interface via his own mac and on a dedicated screen.
