I am pretty sure you haven't tried it yourself. I am also pretty sure the software you mention is significantly more expensive or at least not open source.

Which makes me pretty sure yours was a useless comment.

I've had great experienced with it. It's almost certainly not as full-featered as premiere pro, but it runs buttery smooth and robust, while Premiere Pro kept crashing frequently and was a bit tedious to use for simple tasks.

> I am pretty sure, this thing solves half of the problems the above solve, and it does it half-good.

What makes you pretty sure?

It's FLOSS (GPLv3). There are very few free software video editors. Another good one is kdenlive, which a few years back I liked better that OpenShot.

With enough time, love and leadership direction, any art-focused OSS can be the next Blender or Krita :)

"how does this small open source tool developed from the good will of developers in their free time compare to the juggernauts of the fields, with millions in revenues ?"

You know it very well, why do you pretend to ask ?
