To try to be clearer: I would like my duo to perform on a video. I want to record the audio simultaneously, using Mark of the Unicorn 8Pre and 896 (firewire interfaces) stored on a thunderbolt harddrive. The interfaces have the ability to use a clock, from the Mac, or from the interfaces themselves, which would be nice to lock in on video. I don't have any idea if the MacBookPro can record or create a sync in the video. Then, the audio will be tweeked/mixed for optmal sound. If there is no common clock, will the digital sound be in sync with the video, using a clapboard at the start? Could I drop frames of the video if it gets out of sync? I can live with raggedy video if I must.
I appreciate that this displays my ignorance of Apple video. I have worked professionally making music for videos, but have always worked for video producers with high rent equipment, and great skills. I need to work on the cheap with what I have or can borrow to make some videos to get gigs. I appreciate any advice.
