jitter

If you want to drive a slider using the current time information from jit.qt.movie, you can send the ‘gettime’ message into jit.qt.movie to cause the ‘time’ message to come out, and use that to drive the slider.

Storage of large quantities of numerical data is exactly what Jitter is for. You might commonly think of the data in Jitter matrices as representing pixels of a video image, but in fact you can use the jit.matrix object to store any large sets of (multi-dimensional arrays of) numbers, which can be used for any purpose.
