I have tried several different things and still can't figure out the answer
Editing in Final Cut Pro 7
I use a sony NX5 as the safe shot on weddings
I use clip wrap to convert the AVCHD to Prores LT
When I link up the Canon 7D footage with the NX5 footage and export as a reference clip it wants to render out the clip and takes about an hour when it should take only 1minute.
Both NX5 & Canon 7D are shooting full hd at 25fps progressive
the information displayed in FCP seems to be the same.
I'm sure when I first started doing it this way it worked fine.
