Workflow Confusion - advice needed
After reading the docs and following tutorials I am still confused about the workflow in resolve.
I work mainly on 'art' style videos (not regular story or documentary styles) and in a very non-linear experimental way; I change footage in response to a new feel about the content, or in response to a musical score. I also continually adjust effects and edits, and I always run into problems, and sometimes even dead ends. I feel I'm missing something about the Resolve workflow.
E.g. Fusion
I'll bring in green-screen footage and want to immediately pull the key and add garbage mattes so I can visualise the resulting composite. So I make the green-screen footage into a Fusion Clip and do the keying work. I then go back to edit the key'd shots in the timeline with background clips when I discover the need to do a planar track on the background to match-move the keyed footage with it. I make a new Fusion Clip from the previous Fusion Clip and the background (nested).
This all has me going in and out of Fusion and creating nested Fusion clips. These eventually get problematic and overwhelming to manage and awkward to tweak as any changes have a compounding effect on other elements. I even start to get issues with keyed areas breaking down (often white corrupted patches) etc. I also get stuck sometimes where I can't do what I want and end up having to reset and rebuild the Fusion work - this time with all the current clips in the right places...
When I want to use Color tools for the key'd shots to fit the background I can no longer do it in the Color tools as the clips to color are nested in Fusion etc - I have to use Fusion nodes for color instead which are different (and not so comprehensive).
Am I simply doing the workflow wrong? Or is there a better way?
p.s. I have found that if I don't 'wrap' some clips in Fusion they can easily fall apart when teh compositing becomes more complex.
