I'd like to use a mac tower to capture two HDMI inputs to two separate files simutaneously. My goal is for these two files to start at the exact same time so I can load them both up into video editing software after transcoding them to something workable, and edit. I don't want to have to have two programs running, or two instances of one program, or some funny nonsense where I have to line things up to capture two inputs. I am happy to pay a fair fee for it, I'm not looking for freeware. I've looked at Blackmagic's solutions but their software that comes with the card only records one input at a time. In a professional environment, I undersand that you have to have timecode to do something like this, but I am trying to record an overall-view camcorder alongside a microscope camera, and it was like pulling teeth just to find a good HDMI microscope camera(most are USB), finding one that supports timecode is just asking too much. I don't mind if it isn't synced to the microsecond, so long as I am not running two instances of a program and running the mouse from one to the other to hit record on both, I am happy. I have found software that does exactly what I want but it is Windows 7 only. I'd really like to avoid using Windows 7.
