Well, if you're using different locations as we are in our upcoming vignettes, you certainly shouldn't be filming at location A, location B, location C, then back to A, then back to B, then back to C. Film everything at A, then B, then C. Then turn it over to the editor.
For our upcoming full-length episode, "The Night the Stars Fell from the Sky," I've planned shooting Location A, Location B, etc. all the way until Location J. I'm in the midst of breaking down the script by location and by cast. I'll be heading out this week to take still shots of the locations from the three set ups I think each location will deserve. The only time I suspect any problem will arise will be the sunlight. I want to make sure it matches in the shots.
