This echoing effect over time is one of the things I’m really drawn to regarding aerial movements (which I’m most drawn to in multicordes, where you can see in the reverberations of the cordes, and other spinning apparatuses), and I wanted to emphasize that digitally.
I wanted to use a video capture of my recent multicordes performance at KAC (recorded by Lucy) to generate a trail effect of movement to explore this concept.
The operation uses a cache variable to extract frames from the input video, and then I manually tweaked the output to show an interval of about 10 frames in between each ghosted trails, which shows a decent separation of frames and spacing based on the speed of my movement.
The image addition operator is simply “brightest”, which works because of the very clean black background; a more complex background would require some pre-processing or a different strategy.
Also shown is a video of corde lisse straddle-ups during training at Circus Center put through the same effect – another motion pathway that benefits from this kind of visualization, with lots of variation in both X and Y.
