Slitscan

slit scan capture #slitscan using #hydra.js on a half-time video of my best split-grip #pdayesha. would love to realtime-project this onto the dancer going out one side of the pole like this. right now speed of the trail is dictated by the amplitude of one of the fft bins for a bit of a dynamic effect — subtle in this more ambient track. ...

i wanted to explore slitscan as it affected multicordes videos. i find the jitter on the visual lines of the cordes to be ideal for showing the action of the slitscan. i developed a “short multicordes” apparatus specifically for this video (gymnastics ring with hitched nautical sash cordes (properly whipped ends this time)) as i had extra material lying around from original development. extremely simple python code in a local notebook below ...

i think slitscan looks most compelling when drawing from regular or easily-traced temporal movement paths. this is just a simple straps spin with no special tricks, but the legs demarcate a clear double-helix (and for a beginning student, could potentially deliver information comparing one leg’s motions vs the other in a flare). ...
