This is a demo video of the new version of the v002 Screen Capture plugin for Quartz Composer 4.0.
2.0 allows the plugin to work natively within the editor as any other plugin ought to, has the ability to capture from screens other than the main screen, has interactive window selection, and tools to clip title bars and other window features easily out of your active capture area.
You can use this to capture any image and bring it into your Quartz Composer compatible host app for post processing, like VDMX, Coge, etc.
Use this to sample Processing, Flash, Photoshop or Corel Painter painting sessions, Blender or Torque games, MS Office, etc etc in QC to mix with your 3D models, Quicktime Videos, etc.
This new version is unfortunately limited to Mac OS X 10.6, QC 4.0 due to use of new APIs available only in 10.6.
