I've been spending the Christmas break learning more about interactive quicktime, max/msp and isadora for creating music and video and publishing them on the net. Below is the first piece I've created. I went a bit overboard on the effects in Isadora but it's an original piece and I learnt from it so I'm happy with it overall from a learning experience point of view.

How I created it:
- first I took videos with my dvd camera
- then I used DVDx to convert the .vob files to mpeg2 files which quicktime could open. when I installed winamp a couple of weeks ago, I noticed it can display video now also, though strangely, sometimes the winamp videos were upside down whilst they played correctly orientated in quicktime. (perhaps I used strange setting whilst encoding?)
- then I imported the video into isadora, and patched up a storm whilst trying out some of the effects
- I can only save 5sec clips from isadora as I'm using the trial version whilst I work out if I'll use it regularly in future. I'm hoping to learn how to do similar tasks in jitter (max component) as I'll have more control of what I'm doing, even though it's very quick and easy to get things done in isadora without having to know the code. still yet to decide on this.
- once I had the processed video clips, I opened them in quicktime again and joined them together - hence the rough edits
- then I made a couple of text tracks in quicktime and added these in. I tried out the eZediaQTI app whilst learning about the text tracks but decided on doing them manually in quicktime and editing the controls with notepad.
- next, I opened the gps data music patch I made in max/msp and ran it with the soundwalk recordings I made the other week whilst at Mission Beach in Auckland. unfortunately, the mic was picking up a lot of noise from the wind blowing past the mic pickup so there's a lot of distortion. I filtered some of this out in audacity and flattened the audio into one track.
- then I added the audio track to the video with text quicktime movie
- then uploaded the finished piece to archive.org using ourmedia and viewed source on the movie's ourmedia page & copied the quicktime player code here

well, I'm sure there's a quicker way of doing it! which requires less processing and time, but this was an exercise in creating an original piece from start to finish. as you can tell, I'm not a designer or very good programmer either, but I'm happy to finish number one. here's hoping the subsequent efforts will improve and be done more efficiently. I could have used the original unprocessed videos but they seemed a little plain. need to find the right balance I guess..

here's a screen shot of the isadora patch:

max/msp course @ Goldsmiths college, London - gps data music patch project

earlier this year I did a max/msp course at goldsmiths college. the class was taken by the very clever and talented sebastian lexer who puts on the interlace events in london and performs at various events and festivals. if you're looking for a max/msp course, I highly recommend this one - whether you've used max/msp before or not. the projects by the other class members were really cool also!

notes from workshop: GPS for Artists - A Locative Day Out workshop with Ivan Pope at Isle of Wight

- class exercise showing how gps uses 3-4 satellites to track a location

- originally the military built gps
- variance - this was removed recently which meant the accuracy of commercial (non-military) gps devices increased

- you need line of sight to 3-4 satellites (3 for location, 4th for altitude); 3 minimum

- sometimes in cities, reflections from buildings stop the signals being received

Ivan Pope presents A Locative Day Out

The satellite based Global Positioning System (GPS) allows us to record
basic information about our location, direction, altitude and speed.
Using small hand held devices, artists can record and interpret this
data to create mapping, locative, durational and other works. GPS allows
us to take back knowledge of our whereabouts, and to annotate this
knowledge, or to reuse it as we wish.

Artists can use access to this locative data that forms the background
to all our lives, to add another layer of information to work. Whether
we want accurate information or chaotic disinformation, the gps
satellites transmit unceasingly 24 hours a day, not caring whether we
make use of their datastreams or not. We can anonymously take up their
offering and convert it to human data.
