By fortuitous circumstances, I happen to edit two different projects on two different editing programs, on two different operating systems over the month of July. Although many editors-including yours truly, likely to claim that our skill sets are not tied to a particular program or a platform, but the harsh truth is that the post production is heavily technical, and dependent on technical expertise even if only to edit faster.
An opportunity/experience like this lends only to a freelance editor like myself, I reckon, and offers fresh perspectives on post production workflows.
