motiontriggered quicktime

I’m trying to put together a fairly simple project using MAXMSP 5 and I don’t exactly know how to set it up. The Idea is that I have a looping quicktime-video which consists of say a landscape wherein light is shifting. Then, I would like to have a motion detector installed in a part of the exhibition space that triggers a bug flying through the landscape and the sound of the bug. Anyone ideas on this?

Thankx!!

have you any idea where to start? if you dont, you should work your way through the max, msp and jitter tutorials, because they explain most of what you will need.

As far as developing the content, the above post is a pretty good idea regarding getting the patch together. One way to approach it is via layering the bug video containing an alpha channel over the background video.

The trigger could be done either with a live video input and objects such as cv.jit

or if you want to trigger the video via a physical sensor such as IR, you could use something like and arduino (http://arduino.cc/) with firmata for max (http://www.co-lab.info/maxuino-007.zip) or another interface like Phidgets (http://www.phidgets.com/) both these options work with max.

I hope some of this information helps.

Hi all,
So far Ive figured out that I will be working with video input in stead of a motion sensor. And that I will be using a differentiating- patch as described in one of the tutorials. Im lucky to have stumbled onto that tutorial because there are sooo many. Any ideas on what would be the best basic tutorials to start with?

Thanks a lot!
