Because the angles of the projectors were so extreme, each frame of each video had to be distorted trapezoidally by varying amounts to make it project as a square image. This required a considerable amount of calculation and batch processing using Photoshop, Director and Final Cut Pro. 30 seconds footage at 30 frames per second = 900 frames per clip, times for clips = 3600 individual pictures that had to be manipulated, recompiled and recompressed as MPEG. This scene shows the four individual distorted clips running in sync.
