I have final cut express 40.1 I have a new Nikon D5100, takes amazing videos When I bring it into final cut express it lags really badly in the viewer. I have it so small where it's like at 12% it's even worse if it's any bigger. The videos are directly on my mac. I have tons of room on my hard drive. I don't know what it is! it's really annoying. When I render the videos it's totally fine. But it's going to take me so much longer to make this video if I can't see what I want directly in the viewer. HELP? I have a deadline!
