So I've never been able to get camera hardware to work quite properly with QLab, between S-video capture devices that randomly drop and other converters that Mac OS plain doesn't recognize. In using QLab to drive live video from a composite-out mixer (I would run straight out of the mixer if I didn't need to add custom geo to things), does anyone know any reliable video capture/converter/input modules that work with a MacBook? It's not a Mac Pro, so altering the machine's internal hardware is not an option.
