| We usually look for references
for live images’ analysis in the history of light shows and
visual music, according to a chronological paradigm that associates
contemporary club video projections with the color concerts of the
XIX century and the psychedelic wet shows of the 1960s, among other
artistic manifestations. This approach is related both to the non-narrative
appeal of live images in general, as well as to the conditions of
rendering of a VJ projection, where the message is generated, edited
or composed in real-time – methods traditionally associated
with music presentation.
The real-time processing of visuals seems to be directly opposed
to the most conventional dynamics of moving images’ exhibition,
the century-old cinematographic screening. While in real-time processing
the message is generated (if not composed) at the same moment it
is expressed, in cinema screenings the message (the movie) was generated
months before its expression (projection), in a complex process
that goes from scriptwriting to post-production, and may take years
to be completed.
From a practical perspective, however, the difference between both
conditions of rendering is subtle. Movie exhibition is not an automatic
routine, but an active effort that demands a lot of technical expertise
from the operator. It involves changing film rolls, adjusting the
audio mix, monitoring and correcting the image’s conditions.
The movie projectionist, just like a VJ, must operate in real-time
to convey the message. In a certain sense, he is also a performer,
but his performance is negative: he must avoid that the feature-length
film loses its coherence. The VJ, on the other hand, enacts a positive
performance: he creates coherence from distinct visual samples.
