so if you say “cut to zone yadada” before placing your characters, would you also have to write @CHAR stands screen right in zone yadada?
Yes, place your characters at the beginning of the scene in the zone you want. Then when you cut to that zone, your character will already be in the zone.
INT. BACKGROUND - DAY &CHARACTER stands [position] in zone 2 @cut to zone 2
Or if you want your character to just show up in that zone later in the scene and don’t want them to be there at the beginning, just do this:
INT. BACKGROUND - DAY #sometime later in the scene &CHARACTER stands [position] in zone 2 @cut to zone 2
