That’s why I’d say an establishing shot of some sort might help.
I agree! I just don’t think there is one available. You’d have to make one up, and that’s a ton of work.
Unless the shot being added to the sequence is an establishing shot, the sequence will never not be broken. The thing that would fix it is an establishing shot, and there isn’t one you can just pull and drop in from somewhere else because of how they edited the final product. You’d have to kitbash one together.
