As the videos go on, Makoto has information from previous timelines, which in the movie looks fine, but in a single timeline makes little sense. You don't need to watch all of the videos to understand the movie, if you haven't seen it, but I think the Original Timeline, Makoto Resets Her Day Timeline, Harmful Effects Timeline, Kosuke Death Timeline, Stopped Time Timeline, and Final Timeline are the most important. I also included everything that happened in that timeline, so there is a lot of repeat between the videos. Feel free to jump to later sections to see what changed.
