Jitter Tutorials Start

At last…
jit.qt.movie’s primary job is open a movie and read each frame one after other into RAM for easy access by other jitter objects.

jit.window gets that data in the RAM and shows it as colored pixels on the screen. (external window)
jit.pwindow does the same thing in the workspace.
**
mousestate** gives mouse coordinates of the screen with its outlets.
**scale **scales a input range of values to output range.
scale 0 600 -1 1

rate is the playing speed of the movie. 1 is the default. -1 is reverses the movie.

we can map our mouse coordinates as the playing speed of the movie by sending this value by rate $1 to the inlet of the jit.qt.movie.

so we have setcell object where we can set the exact point of the matrix data and display it on the pjit.pwindow.

it works like this: setcell x y val 0-255.

pack object gets number to be packed and spits them as a pack.
pak is similar to pack but all inlets cause outputs.

here is a small snippet that uses pak and allows you to change the matrix data instantly which you can see on the jit.pwindow plus max window.-
