Video feedback is perhaps best known for its appearance in the film clip to Bohemian Rhapsody. It’s not a particularly popular effect that you see too often, as it’s rather messy to set up what with cameras filming screens and what not. Regardless, the effects possible are glorious, as demonstrated by [Dave Blair] and his amazing video feedback kinetic sculpture.
No computer is involved at all in the process – it’s just classic, old school video feedback. It’s produced by pointing a camera at a screen and feeding the image back to that same screen. Three cameras are combined with twin video switchers and a beam-splitting pane of glass, along with a source image via an HDMI input.
By turning and spinning the various cameras, [Dave] is able to generate beautiful curving fractal-like effects using the source imagery, with a rainbow of color melting and warping together as he interacts with the sculpture. It’s a beautiful effect and something we’re surprised we don’t see more of in the video industry.
Hopefully [Dave] is enlisted to put his machine to work on the next [Doja Cat] film clip so we can get more of this goodness. Video after the break.
