I know that the subject has already been treated but I still have a doubt ...
Is it possible to import a live feed from an analogic cam with an acquisiton device on USB 3.0 port ?
In brief, can I use something like this http://www.blackmagicdesign.com/products/videorecorder/
to import 3 analogic cameras in a Mac mini with 4 USB 3.0 ports ?
Thank you for your help
