Hey Cayenne! I'm about to go read the rest of your responses in this thread, but first off I think you should drop resolve from the equation. I don't think there is anything you can do with it that you wouldn't be able to do with FCPX's built-in color correction and/or Magic Bullet Looks. If DSLR video was 10-bit or 12-bit then maybe it would be worth having Resolve in the mix, but with 8-bit it's just overkill and only adds complexity to your workflow.I kind alike Resolve....when the workflow works, but mostly in that the controls on Resolve are much more intuitive to me for color correction, with the color dials, and the nodal workflow, I find it it easier to keep up with my different corrections.
I just can't seem to get the same control or at least "I" haven't figure it out with the slider controls on FCPX. I also find the scopes to be a bit easier to see and work with on Resolve vs FCPX. For instance, after seeing a colorist describe how he was able to fix color balance by finding a black object on the parade scope, and correcting it, and doing the same with a white object on the scope and doing the same..that white balance would be set...I was able to do this much easier with the controls on Resolve vs FCPX.
I agree it is likely overkill for canon footage, but I find that I am more comfortable with the controls of Resolve than with FCPX. But hey, I'm good to try to learn as many different paradigms as I can...so, when the xml from FCPX to Resolve and back breaks, I concentrate on doing it within FCPX.
