OP I'm happy to pass on what I can, but obviously this is only my own experience and no way intended to be cast in stone.
I think, well I know because my agent has always said so, that my novels are all very filmatic.
Not a conscious decision on my part. Possibly borne of the fact that I love telly and film as much as I love books, maybe more.
My method for writing a novel is pretty rigorous ( or at least it used to be, I think I've now imprinted it into my subconscious so I still do it, but in a less obvious fashion).
I choose a structure in advance. I work out a basic plot in advance. Then I plan each scene on a sheet of A4, stating who where what and anything else I can see.
When that's done I write the novel.
I also tend to write series fiction so I've learned ( the hard way) to keep things back and to sow seeds, ready to sprout in the next book. And most of all not to plant things that will be a complete balls ache to deal with in the sequels!
So when I decided to make the transition to script writing, the method was half way there ( as opposed to lots of novelists who write much more organically- which doesn't lend itself to scriptwriting. At all.)
My first commissions were for an existing show and this is fab training. Basically the characters already live and the show runners have decided what's going to happen. The writer's job is to make that interesting, within timed parameters.
When I came to write original stuff, I imported that way of working. And I found it was pretty much standard for script writers.
Work out who your people are. What they're going to do. What the show is about thematically. Do this way way before you even open Final Draft ( I'm still using the 09 version).
Then draft your story beats. I do it by hand. I think there's a function in FD but I prefer to scribble it down.
Once you're satisfied with the beats, draft the scenes around them. Again I do this on paper.
When you finally have all the scenes drafted, check then carefully. You might need to reduce the number of sets you've used. Or actors. Look at your transitions. Check that they work.
Now you can start on your script.
Pick up your first A4 sheet or index card or whatever you used and work out how you can adapt it using the least possible time and words.
Rinse and repeat.
As I say, this is just how I do it.
