This may a Z1 question, only...
OK - I found an incredible way to sync Z1 cameras.
You just set the TC to "Free Run" and "Preset".
Put all the cameras in a row and use the Z1 remote to reset the TC to zero.
All the cameras are now running in dead sync. No matter how the cameraman turns the individual camera on or off, the time code is still in dead sync. Wonderful !
But now, when I capture to Vegas, is there any way to find that original TC for layout on the timeline??
