bring in your two clips into your assets box.... rename them MC1-filename ..then MC2-filename for the other
(so you don't get confused between other tracks)
then simply pick a spot anywhere in the song... preferable a light change or a camera flash and set the in point at that spot on both clips..... then you go to modify > make multiclip....
then you get a multiclip file with both of your files synced... then set your in point to the front of the multiclip if one cam starts before another if not just leave it ......
the drag your multiclip into the timeline and sync your DAT audio up via drum hit or guitar rift and your all set...
let me know if that doesn't make sense...congrats on make the switch to apple... once you get it down you will be amazed how good a program is... I love it... doing a six cam mix on it right now
