So I have used FCPX on my Macbook Air for a couple projects which turned out well, except for the fact that a 10 minute video takes 6 hours to render in 720p. Final Cut lags and freezes alot when I am using it, so my question is this: Is it normal for FCPX to be this buggy, or is it that high-end video editing is not meant to be on a MBA? I am planning to purchase a new Mac in 2015, so getting a new one now isn't an option. My specs are 128/8/i5. Is using FCPX on a MacBook air practical?
