Noisefields
The Video Noisefields (1974) by Steina and Woody Vasulka is an important example of early formal and technical experimentation with analog video. The video runs for twelve minutes and five seconds and materially visualizes the electronic signal. The video switches between two sources throughout, which creates a flickering effect. The imagery is based on the deflection of electronic signals, and a colorizer is used to add color variation. In the video, a circular form materializes on the screen and presents a division between inner and outer. A pulsation between the two is sustained throughout.

The Signal
Noisefields focuses on the deconstruction of the video signal.

Audio-Visuality
The video camera, opposed to the film camera, offered artists the ability to record and play back sound and image simultaneously. Because of the close affinity between sound and image, many artists saw the video image as moving music Noisefields video explores the connection between sound and image, as there exits a shared mutuality between the audio/video signal.

Video Processor
Like many other other video artists of the time, the Vasulkas used the Rutt/Etra Scan Processor to make the video. The machine was developed in 1973 by Louise Rutt, Steve Rutt, and Bill Etra, and allowed video artists to more wholly unite sound and image. The machine was of particular interest to artists who wanted to deconstruct and analyze the video signal, in order to exert greater control over the modulation of electronic signals. The Scan Processor lifts "the brighter parts of the image...in their temporal progression, according to the voltage, causing the horizontal lines to deflect vertically and sculptural forms to be generated." Using the processor, the Vasulkas were able to create abstract images from the modulated video signal.
