The imagery in the sequences involving recorded brain impulses in 'Until the End of the World' (1991) were achieved with early high-definition video. Wim Wenders and technicians at NHK (the only facility which could play back HD video at the time) worked for six weeks on these sequences, and intentionally distorted the imagery to create strange visual effects; often recording a fast-forwarded version of the image, then playing it back at normal speed.
