Jitter in javascript

Why would you write Jitter code inside a js object?

  • Math expressions
  • File IO
  • Borrowed code
  • You’re just that way

There are three Jitter javascript tutorials (built in to Max) 45-47

The Max javascript documentation is generally far flung. A helpful reference by Tim Schenk https://reactivemusic.net/?p=17445

Here’s an example to get started with. It downsamples a movie and changes the background color. Something I often dream about.

Using this device on Mac OS X 10.9, analog video input shows up as a system device. It also works as a firewire video output device.

Input

 

Using Jitter you can get real time input from analog video devices like cameras and VCR’s. Here’s an example using jit.grab (Max help file) to get input from an analog camcorder.

Not modular

Two weeks ago Christopher Konopka demonstrated modular analog video. This week we will explore analog video made from found objects and circuit bending. https://reactivemusic.net/?p=18982
