Evanescent Evidence, a video film of duration 4’16” made in July 2021, is entirely based on 60 random videos downloaded from the internet in 2000, their durations ranging from 7 seconds to 4 minutes. That year I began to use a PC and to use the internet on a regular basis. The videos are in 320 x 240 pixel format. Every pixel in every frame derives from the corresponding frame of a film randomly chosen from the 60 videos: at the start about 1/60th of the pixels derive from one or other of the 60 films. The audio track accompanying each frame is taken from a random 8 of the 60 soundtracks. As the shorter films come to an end one by one, dark blue pixels and silence are inserted as placeholders. As a result the number of downloaded pixels and samples in this video gradually decreases with time. They vanish completely at the end, hence the title.
