Derived from Ernie Gehr's Serene Velocity, Lossless #4 is the result of a digital file's debugging routine that reveals vectors describing apparent movement in the frame. Having removed the picture, thereby isolating these vectors, the formal qualities of Gehr's film are detectable. The hypnotic effects of the shifts in the lens’s focal length in the original are now substituted with a purely graphical representation, creating a perverse replacement of the optical effect of the original.
