Is Davinci Resolve 16 good for beginers?
As far as I know, in Resolve you only have to pay premium for the cloud collaborative features.
Its not beginner software like iMovie or WMM, but rather comparable to Premiere, the cheapest rate for which is 20/month if you have a student email.  Among free software, Resolve is definitely one of the best options out there.
While it is a professional tool, it's very intuitive for basic functions and it has the core features you'll find in other professional editing software.
Edit: Free version includes 4k
