Resolve is used on tentpole movies throughout the film industry. Not for cutting, but dailies, grading, DI mostly. Vegas and Premiere are... not.

@diamount I honestly wouldn't bother with any paid courses. All they can do is show you how to use software and there are zillions of Youtube videos for that. I'm quite wary of your idea as well. "Video production" is a rather wide-ranging term and at the lower end is absolutely full of chancers and people with no clue (no offence). Starting out on your own is probably very difficult to make any sort of real money. Why not go and get a junior position at a corporate video production agency or something to understand how it all works?
