Blast from the past

Blast from the past

2005-02-13 by Richard Brewster

I was web surfing and found this:

http://www.audiovisualizers.com/toolshak/vidsynth/djones/djones.htm

I worked with Dave Jones in the seventies at the ETC.  The picture in 
the upper right corner shows Dave using one of the audio synths I built 
for the ETC (two yellow boxes) to control his video synthesizer (the 
white box), which was made for voltage control.  To the left, just above 
Dave's shoulder, you can make out some yellow and brown equipment in 
racks.  That is some of the video synthesis equipment I had built.

Yikes.  Sometimes the internet can be scary:

YES, thats it!!  a video interface/FX module.. 

so Richard, whats the skinny with video/visual synthesis?  ...  Say I 
want a module that I can plug an RCA cable into and plug the RCA's 
other end into my TV's video in..  what could we do, what could we 
generate?  Maybe a module that we pass video through and we impart 
effects or changes to the video signal..  In time with our sounds of 
course.

RE: [motm] Re: Blast from the past

On the Audiovisualizers site there are a couple effects boxes for sale
What I find more interesting though are plans for the TVFX at the bottom of the page. I checked it out a while back. IIRC it is based on an analog color encoder chip. Unfortunately that particular chip is obsolete (and it is PAL, too). But if you analyze the circuit you'll see you can adapt it to any analog color encoder chip. The TVFX circuit is basic but its just begging to be modified. Playing with encoder chips is something I've wanted to do for a while. Has anyone else here messed around with anything like this? Or are there any other resources you can point us to?
Thanks.
Mike

I was always more interested in music and audio synthesis than in 
video.  It was a video artist, though, Walter Wright, who gave me his 
Electronotes collection, thus introducing me to the magic.  The 
combination of audio and video synthesizers was, as you can read in my 
audio synthesizer manual for the studio artists, primarily for VC of the 
video synthesizer, as well as having some audio oscillators to jazz up 
(mess up) the video signal.  At the ETC the video art generally 
supervened over the audio art.  LFOs and other slope generators were 
used to automate some of the mixing and clipping in the analog video 
machines.  It was pretty basic.

I believe that video synthesis these days is primarily digital and 
computer contolled.  However, the ETC does have a tradition of 
integrating old analog equipment with newer technologies.  There is a 
long history of video synthesis applied to video art.  Check out the 
experimentaltvcenter website.
