BlackMagic does quite a few innovative things. I have one of their cameras, and thus a paid license for Resolve. It's my primary editing tool. I've even done a music remix in Fairlight just to see if it could be done.
But their priorities are not always well-set. In Resolve, significant problems remain while more and more functionality is hastily slapped on.
The so-called "integration" with Fusion remains very poor. Compositions' presence in timelines is extremely fragile, and inexplicably degrades source material's resolution to that of the target timeline. This means that if one of your timelines is HD but you bring UHD clips into Fusion, they will be degraded to HD upon ENTRY to your Fusion comp, before they ever get to the timeline. So in Fusion all of your keys and other selective image processing will be chunky garbage.
Also: If you start a project, import your footage, and then drag a clip to the timeline... Resolve will offer to change the frame rate of the timeline to match. But NOTHING ELSE. Every other major NLE offers to match the timeline to the first incoming footage in ALL regards. But not Resolve, despite years and years of vociferous complaints in their forum. This is a basic, expected feature but ignored by BMD.
And finally a core issue: multiple, unrelated node views scattered about. Resolve needs to consolidate them into a single node view for all processing. That would flesh out Resolve's half-assed "integration" of four or five other products and provide a game-changing workflow that is long overdue.
