Cutaways are no problem at all. Just switch to the alternate video but
use the XL1 sound all the time. If you keep both cameras running the
whole time, they will tend to hold sync. In the worst case, you might
experience a frame or two of drift by the end of the hour. I do that
with video all the time. But I never try to mix the sound from two
cameras unless I want it to sound strange.
