Percussa micro super signal processor

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 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
