This lecture introduces techniques and objects for working with interactive/reactive video in Jitter.
The session starts with [jit.qt.movie] and looks at ways to fade and blend multiple sources ([jit.xfade] and [jit.op])
Simple audio-reactive control is achieved through [peakamp~], and frequency conscious control derived via [svf~] followed by [peakamp~]
The session continues by addressing duration based methods for switching video files (read (as in ‘red’) message out of [jit.qt.movie] dumpout triggers getduration query) or jumping to a point in a videofile
The session concludes by looking at unpacking and repacking a four channel matrix ([jit.unpack], [jit.pack]) with operations in the middle ([jit.rota]), other matrix effects ([jit.slide, [jit.sprinkle]), and subdividing and combining matrices ([jit.scissors], [jit.glue])
