That’s a good thought on pacing sade, so I’ve added to my plan “8. Make any changes necessary to better pace the series as a whole”. I think my approach needs to be to first make the best episodes I can, and then to look over the show holistically.
(I appreciate, at this time, that effectively I’m saying I plan to have a plan - but you’ve gotta start somewhere, and I’d like to do this top-down.)
Regarding newsreels, I’m not sure. Consistency will be important, but again, I think quality must come first. Off the top of my head just now, the approach which gives an editor the most flexibility would be opening crawls or Solo-like text, because it’s text you can use to give whatever context is necessary, rather than demanding an edit be made around available sources.
