Coming into this current discussion late, but was the “heads up” at the beginning of these clips always there? Because it sounds clearly added in post, and also… doesn’t make sense with the visual? We hear Poe (I think?) say “heads up,” but then he and the rest of the cast spin around in sudden surprise, like they all just hear the horse hooves at the same time and nobody actually said “heads up” in the scene because nobody was keeping watch.
Probably not worth doing anything about, especially if it’s been there since the theater and I never noticed it, but these clips all starting with that moment just made it stick out to me.
The placement of the “heads up” line is a result of trimming the blade protractor thingy, the line was originally on a shot of Rey looking at the thingy whith Poe turning his head as the horses walk in on the background. I think removing it is kinda awkward since it makes the trim more noticeable, now it just feels like two different scenes fading into eachother. Which is what it is, but the line helps blend them together.
