It’s unclear from your post, but I would make sure you’re sourcing the movie from the most recent release of it. It is a much better video presentation of the movie versus the 2009 blu ray.
I didn’t specify on that because the main source video for the edit can be easily replaced in the timeline, if it has the same length which should be the case. If not it wouldn’t be very difficult to find the difference and fix it. Currently I’m using the 2009 Blu Ray but will replace it with the new one before finishing the project.
