How do I get live feeds into Ai?

Live video can be used as a source by selecting one of the patches named ‘LiveVideo’ in the media browser ( Menu Bar > View > Browser ) and dragging it into the media bank.

Some of the patches are specialised for specific input card types and are named accordingly, however if none of these match the input card or usb camera you are trying to use, the patch called LiveVideo.scb should suffice.
