I never seem to have time to sit down and learn another NLE, like I have with FCPX. I made the transition from 7 to X in 2011 and never looked back. I have tried Premiere, but I always found it lacking compared to X, but Resolve intrigues me. So the open ended question I have is: Is Resolve mature enough as an Editor, that the members of this forum are starting to learn it, because it's time has come?
I have to ask Don, why do you ask? Is it that X although doing what you want and need and is favored over Pr is not in your longer term plans?
The simple solution is to download the free Resolve which does almost everything and use it. 15 release is out so start by cutting in X and exporting via xml to Resolve to grade and perhaps do titles, GFX, audio post and final delivery. You will then get a feel for the program and the edit page is always there to play with.
For me Resolve is my tool of choice as I do post finish not original edit but when I need to edit I find it not only capable but familiar which is a very important thing. Coming from X you might not like it as it is much more Legend, Premiere, Avid like.
