Cons
Con Steep learning curve
Unless you use a front-end (that has reduced functionality), ffmpeg might be intimidating at first.

As well as for advanced colour correction you have get a third-party plugin.
Con Important compatibility and format issues

Con Works only on OS X
Con Color grading is unfamiliar and nonprofessional
