I guess this all depends on how you interpret, in private. I'm a director who operates his own camera, and has a very small crew, so I'm usually near the actor and don't need to shout. When I hear, in private, I interpreted that as off the set away from the other crew. No, you don't want to scream direction over a megaphone from across the set for a quiet, emotional scene, but if you're halfway across the set to begin with that's probably a bigger problem. Most directors I respect either stand next to the camera, or operate it themselves, so they can be in constant dialogue with their actors.
I think sliders are overrated. I had one on my film and still preferred using a traditional dolly.
The only thing I take issue with is, "Don't give direction in public. Take your actors aside to give them notes." An actor is a craftsman like anyone else on set and should be able to take direction on set like you would any other crew member. Only in the rare case where it's something very sensitive would I discuss with them in private, otherwise, it's a massive waste of time to do that for every adjustment.
I deal with procrastination by waiting for it to go away.
A teacher once told me being a “genius” won’t get you straight A’s, it just meant you can get C’s without trying too hard.
I'm transitioning from FCP 7 to Davinci. Hate FCPX (much as I've tried to use it), Premiere looks good, but you can't beat free so I went to Resolve. Moving from FCP 7 to Davinci Resolve has been pretty painless. Similar interfaces and shortcuts. The biggest limitations with the free version is that resolution maxes out at UHD, so can't output cinema 4k, and h.264 performance is crippled versus the pro version.
