well, I agree, SCRATCH's UI is not straight forward.
However, once you got the concept, it'll be amazingly fast.
The comparison to PP, FCP7, FCPX, Logic, Pro Tools is a bit too far-fetched imho as those are editing/audio apps (and for the live of me, I find ProTools and Logic far from being straight forward, really).
I mean.. look at any of the more specialised apps out there - be it Flame, Nuke, Avid, Mistika, or even Baselight, Rio, or Lustre - those are also have their own UI methodology, which might be not as straight-forward to learn as Resolve's is, but colorists who at some point got around the way it's working, are immensely fast on those systems.
It is no different for SCRATCH - and while I agree, it takes a second longer than Resolve, it'll pay off.
The main thing to get your head around is the concept of CONstruct and Player in SCRATCH.
Maybe invest 5 minutes to watch this video:
And, in case you should re-consider, maybe this one:
Else, we do have a very responsive support-crew happy to answer any questions you have.
Also, if you have an idea for a tutorial targeted at Kinefinity users, that we could produce, please also feel free to let me know and I'll try to get it done.
Edit: I'm just realizing, I'm hijacking this thread - will leave this here, but maybe we can discuss on another thread about how to use SCRATCH .
