Review & Preview

Nachdem der Pilotabend ohne Werbung schon wie eine Bombe eingeschlagen hat laden wir gleich nächste Woche nochmal zu einem Open Decks spezial! Von 19.00 bis 22.00 Uhr gibt wieder audiovisuelle Experimente für alle Interessierten, danach feine Beats und Visuals von Hillside Collective, Howdy und Neon Golden. Wer Lust hat mitzumachen sag kurz via Mail Bescheid und rockt mit. Tagesmitgliedschaft: 3 Euro.

Shortly I bought a Matrox TripleHead2Go (analog) Extension Module and discoverad afterwards that it isn’t supported to work with my new MacBook 2.16 GHz Intel Core 2 Duo nor my PowerBook 1.67 GHz PowerPC G4 with 128 with ATI Mobility Radeon 9700, 128 MB. I expected at least the DualHead Mode running on the new MacBook. (According to the compatibility page.) But in fact it doesn’t. There is a new driver for Windows to run the TripleHead as Dualhead (strange enough), but none for Mac OS X. I got frustrated.

Really? Is that possible, such a lack of support for the Apple community? I couldn’t believe it so i wrote a mail to the Matrox Support team. Here the friendly but useless answer:

Thank you for your email. Actually, it is mentioned on our website the Mac models that were tested and are supported with the TH2Go. PowerBook G4 is not on the list, it means that it was never tested and no plan to support it. MacBook can only support the DH2Go and not the TH2Go as you can see in the table below. It is a hardware limitation of the Intel GPU and there is nothing we can do to make it support the TH2Go. The TMET utility to allow TH2Go to work in dual head mode is only available for Win2000/XP.

But still, after that i couldn’t believe that my Powerbook with 128 megabyte of VRAM can’t access the card. Today I gave it a retry. I set the Hz down to 60 and voila. It is working. I didn’t test through all the resolutions. I’m already happy with three times 640 x 480 for VJing. The next shows will feature a TrippleHead-setup. Watch out!

The idea of two of more vj’s playing their own channel/stream and feeding that to the other vj(‘s). So every vj mixes his own interpretation of the sound with the channels/streams of the other vj(‘s). That means they all will fit together, but the more vj’s there are, the more different canvas’ are there … Detailed proposal will follow soon.

The idea of projecting the audience in the past, the present and the predicted (computed) future.

To investigate methods for predicitng movement, (of pixels), within digital video in realtime. As such a setup is simple in concept but computationaly intensive it may be interesting to think about what it would look like. If for example a subject runs from left to right across a screen the result would display the faster moving elements of the subject further right than their origin. It would stretch and extrude the subject with an elasticity relative to the speed of the elements or pixels. So the faster the framerate and higher the resolution the more accurate the prediciton.

This is not a realistic software for current computer processors but as a challenge I will investigate what is possible with current technoligies. Let’s say, hypothetically, you can only process 12 pixels, a 4×3 video matrix. The trick will then be to see what you can do with those 12 pixels. In addition how else could you predict, or what else could be predicted with computer vision and what could it be used for.
