How do you cut / delineate a jump in time within the same space? Is there a standard way to handle this? For example, setting = interior, home office, day. Character A is sitting at their desk when character B enters the room. Character A stands to greet B, they shake and deliver a few lines. Cut to both sitting in arm chairs, chatting about war stories within the same room. Clearly some small amount of time has passed, be it 45 seconds or 45 minutes.
My thought is to continue the int room tone, but perhaps change an element or three of what's happening outside the room. So, if I'm in a residential house I might lay in kids at play up top, then change to a distant lawnmower at the cut. Or perhaps add in some sounds of washing dishes off in the kitchen, etc.
Probably a very simple question with a straightforward answer, but thought I'd bring it up anyway.
