Projection Design

“Projection Design” offers a hands-on approach to the design, planning and execution of digital projections in a variety of performance spaces by using a combination of industry standard and open source research software tools. This blog will serve as an online text for the developing book, "Technical Ecstasy" and link for the web-readings, online tutorials,software resources historical examples, video art and performance examples and essential class communications for Projection Design class taught by Patrick Pagano

VJing: History

During the 1960s and '70s a number of video synthesizers were developed often as home electronics projects by backyard inventors, although a few notable exceptions such as the "CEL Electronics Chromascope" were commercially developed and sold for use in the developing nightclub scene.

In the 1980s the development of relatively cheap transistor and integrated circuit technology allowed the development of digital video effects hardware at a price point within the reach of individual VJs and nightclub owners.

The Fairlight Computer Video Instrument (CVI), first produced in 1983, was revolutionary in this area, allowing complex digital effects to be applied in real time to video sources. The CVI became popular amongst television and music video producers and features in a number of music videos from the period.

By the 1990s, advancements in computing had brought video processing to the desktop computer. Early desktop editing systems such as the NewTek Video Toaster for the Amiga computer were quickly put to use by VJs seeking to create visuals for the emerging rave scene, whilst software developers began to develop systems specifically designed for live visuals such as O'Wonder's Bitbopper.

The first known software created for VJs was Vujak - written for the Mac by EBN artist Brian Kane for use by the video art group he was part of - Emergency Broadcast Network.

Broadcasters by this point had become interested and a TV series on the UK's Channel 4 called Transambient, produced by UK artists Addictive TV put the art of the VJ on national television for the first time. A similar series called Two-Step soon also appeared on German channel VIVA.

The first commercially available and heavily produced VJ software was Motion Dive from Japanese company Digital Stage. By the late 90s there were several PC based VJing software available, including generative visuals programs such as Aesitis and Advanced Visualization Studio, as well as video clip players such as Arkaos and VJamm. These new software products meant that VJs were now regularly taking computers to gigs.

The 90s saw the development of a number of digital video mixers such as the Panasonic WJ-MX50 and WJ-AVE5. Although these mixers were designed for home video editing and low budget TV production, they were quickly adopted by VJs as the core component of their performance setups. Initially, video mixers were used to mix pre-prepared video material from VHSplayers and live camera sources, and later to add the new computer software outputs into their mix.

In 1998, Roland / Edirol released the V5 Video Canvas, which was a hybrid device featuring solid state storage of still images combined with a basic video mixer. The V5 marked an important transition point, where large music corporations saw an emerging market for video performance hardware. The products that followed the V5 have become the mainstay of VJ hardware setups. [2]

In 2001, Roland / Edirol released the V4 Video mixer, which was arguably the first video mixer designed specifically for VJ use. It features MIDI control to enable integration with digital music equipment, and quickly became adopted as the standard VJ mixer. The V4's popularity lead other music companies (notably Korg and Pioneer) to develop hardware designed specifically for VJs.

Today's VJs have a wide choice of off the shelf hardware products, covering every aspect of visuals performance, including video sample playback (Korg Kaptivator), real-time video effects (Korg Entrancer), scratchable DVD players (Pioneer DVJ-X1 and Pioneer DVJ-1000) and 3D visual generation (Edirol CG8).
