Bill Etra, the analog video processing pioneer, has been posting some of his original works from the late 1960s through 2005 on video sharing site Blip.tv. It’s a sort of ongoing retrospective of his work. His techniques are varied, including Rutt-Etra processing (using the hardware he co-designed), hand-controlled oscillator-to-RGB inputs, and laptop-based software rigs.

While not a complete archive, it’s an interesting look back at important works and techniques. I’m glad this is online; it’s hard to find useful archives of older analog pieces simply because most techniques involved were incredibly hard to capture to tape. Usually only re-scanning would work (re-scanning is a fancy term for pointing a camera at a CRT). More work will be added, so check back occasionally. I think archives like this are invaluable for inspiration.

Ed.: We’ll definitely be watching for updates, and hopefully cdmotion can help encourage more documentation of this stuff online. -PK

VJ-U has posted a wonderful livecast on Operator 11 featuring the restoration of 3 Rutt-Etra raster analog video synthesizers. I was fortunate enough to be invited to check the machines out in person and have some time to try and help out. Mathew Schlanger and Benton C Bainbridge help explain the history and unique capability of the Rutt-Etra. Certainly worth a watch for those interested in the art form and unique hardware.

For those unaware of what a Rutt-Etra is, be sure and check out Audio Visualizers page on the subject. There is a lot of history with these machines, and they are still quite competent tools with a very unique look and feel.
