Actually I did do them at the same time, its spotty cause i recorded it into pro tools and used my computer to film at the same time. Still working out the kinks as to how to do this the right way with the gear I have. Any recommendations are welcome as to how to make it better for you and everyone! Thanks for watching!
Check out Soundflower. It's free to download.
I use Logic, and whenever I do a video like this, I set the Logic output to Soundflower, then on Quicktime (or iMovie, Final Cut, etc), I set the audio input to Soundflower. It works very well for me.
