QC Stereoscopic Recorder is my first Cocoa app! It is part of my work towards an MA in Computer Arts. The app is a component of a larger project called “Anamorphica†in a class called “Experimental Digital Mediaâ€. Further documentation of this project will appear over the next few weeks. Basically, I am aiming to make a low-cost open source anaglyph recording and ‘performance’ system.
To use it you will need two firewire cameras.
Performance is improved if each camera comes in on a separate firewire bus. To effect this, I use a Lacie firewire PCMCIA card in my G4 laptop.
I needed a simple application that would capture dual camera input, export to quicktime and make an anaglyph.
I have included “stereo-pair†generation. Stereo-pair generation will come into it’s own when the application can handle full-screen and dual monitor support. Then I may create a ‘Wheatstone’ device (see http://www.stereoscopy.com/library/wheatstone-paper1838.html).
QCStereoscopic Recorder would not have happened if it wasn’t for the wonderful “Quartz Composerâ€. Easy and a joy to use. As I am learning Cocoa and Objective-C, the project is indebted to sample code and open source initiatives.
- demo code from Apple – QCTV / Pierre-Olivier Latour
- the wonderful “Sparkle†by Andy Matuschak (www.andymatuschak.org) handles software updates from within the applications.
To Do
- full screen mode
- improve image contrast quality
- fully implement Apple help
- export print resolution single frames
- implement VJing style performance control
Notes
- Built as a universal binary – untested on Intel
- tested on PPC – 10.4.4
Have fun!

This seems to be giving Quartz Composer issue when I try using two cameras on the G5 I am using. It appears to only like one camera at a time. Your app works fine though. It would be cool if it could use mpg files as a source as well as the display as another source.
