I've got an FCP project that I am trying to export. In the canvas window, the footage is playing fine, then when I try to export it, it starts to skip and looks like it is dropping frames. It seems to be occurring on the clips that I have slowed down, which are a lot as it's a wedding video.
I have tried saving the project to a new drive and copying and reconnecting the original media again. At first it looks fine, but then the same thing happens.
