I hope a couple of the forum folks who do a lot of video with Z bodies like Andre Yew and Clint Gryke chime in - they are *well* worth listening to.
I can understand somewhere where you're coming from. I have an extremely deep and vast technical knowledge of still photography - borne from a few decades of doing this and a bachelors of science degree from RIT in photography, so while I'm probably in the top 1% of knowledge on the still side of things, I'm totally the opposite, maybe an "advanced beginner" at best, in the video world, so perhaps what I've learned so far might be of help.
I'll give you a couple of things to search for in youtube first since that's your question, before I go into what I've learned so far.
Editing
I've actually found the Davinci provided tutorials on editing to be quite helpful, if a bit long. Any other questions about something, I usually just google them. It's in the domain of color grading where my suggestions are far more specific...
Color Grading
- Anything Cullen Kelly produces
- Anything Darren Mostyn produces
I'd honestly ignore everyone except those two and if you hang with it - meaning, you're aware this is a longer learning curve than many of us might want to admit - you'll find everything you need with those two guys.
Item #1: It's a long, steep learning curve, and that's okay. Even if you know a lot about other things, it's best to admit to ones self that the world of video is just different, and at times complex.
What I've found so far - meaning as I do more, I learn more...
- Ignore the temptation to shoot everything in 8K NRAW unless you're doing something extremely amazing and hyper important that you'll never do again. It's overkill for most everything. Shear overkill. I know a couple of people in video production professionally - that's what they do as their main job - and none of them ever shoot raw, even though their cinema and mirrorless cameras have that capability.
- My suggestion - that may get overridden by Andre or Clint if they see this LOL, is to try and utilize these two things to start, and to learn how to deal with them.
- 4K/60 Prores 4.2.2 codec
- NLog instead of SDR for your color. This is "harder" because one has to learn/get used to dealing with log footage instead of what we're used to with our still cameras, but using Nlog gets you into the Rec 2020 color space (wider color gamut) and has more dynamic range than SDR. Forum member Horshack has done some nice videos on dealing with NLOG, and I strongly suggest you search for those as well as the two guys mentioned earlier.
- Leave HDR for the future when you know the basics really, really well.
- Don't skimp on CFE cards, Seriously. Skip the garbage, skip the cheap. Most problems people have with drop outs or other issues are cards that are not up to the task. I use the prograde digital cobalt cards myself; mostly these have been upgraded to the new Irridium cards, but one can still find the cobalts at the major photo stores in NYC. I've never had a video issue with these cards.
- When you get into color grading in Davinci
- Again, check the two guys mentioned earlier
- Try to wrap your head around the concept of nodes, and how they can occur in different "places" (at different levels, as in - at the clip level, at the timeline level, or even at a group level) - and pay attention to the videos where that is discussed.
- Try to wrap your head around CSTs for your color management - again, see the videos from those two guys, but in Nikon land, I prefer the CST (Color Space Transform) approach over the Nikon provided LUTS, even though the last technical LUT from Nikon after they purchased Red is way better than the original. This will take some time to understand/learn, but well worth the effort.
- Really try to understand what the various monitors (waveform, etc) are telling you - so you can see where adjustments need to be made, and where color casts exist that need to be addressed.
- During shooting, try to keep at 180 degree shutter angle (the last Z8 firmware update allows this to be set in shutter angle as opposed to photo shutter speed terminology), and get your white balance correct as best you can. Sure - if you ignore my earlier advice and rush off to shoot 8K NRAW for everything, you can change it, but the guys I've talked to suggest learning how to get this right so you don't have to rely on the crutch of NRAW.
Overall, while I don't expect to be a video expert, my advice is "have fun". On my last big landscape trip, I devoted half of the time to still photography, and the other half to video, mostly just to challenge my brain to think differently, which also means to grow. As one gets older, particularly if they know a lot about one thing, it's common to get obstinate and bull headed, and I think challenging oneself to learn new things is hugely important.
Good luck!
