For my own edit, it uses Digimod’s edit as a base and I incorporated some of your ideas. The edit I came up with follows the narrative of video about fixing some of the pacing issues which I do agree with!
I am currently messing around with removing Vader and mention of him until the Corridor scene. Most of the issues that need to be addressed are the music transitions from scene removal or trimming to do so. Here are the Vader scenes AND mentions of him:
1.) The first scene to remove is the Mustafar scene with Vader and Krennic. The only thing to really work on is the transition from the Soon-To-Be-Rogue One crew scene in the stolen Imperial ship (After Jynn and Cassian’s argument) to the Rebel Base debating on what to do. It has to do with transiting the music.
2.) The next tinkering is the DS arriving on Scarif. Radus’ main go to guy says something like “giant mass as appeared” and we see the DS behind the clouds on the planet. We then jump to the DS with Tarkin and his go-to-guy. The dialogue goes something like:
“Do we attach the ships?”
“Vader takes care of that, we focus on base, prime it up”
There are two things I am thinking/playing with on this section. A) remove all the dialogue. We see the DS and we shoot back to Jynn and Cassian taking the elevator. B.) Abbreviate the dialogue to JUST Tarkin’s part about targeting the base the base. The main issue is the music transition as usual. However, I have more thoughts after going over the next sections.
3.) Next is Vader’s Star Destroyer jumping in and attacking the fleeing rebel ships. We see some shots of him looking upon the rebel fleet getting hammered. Simply remove the shots of him and tweak the music since it changes from a stronger music score to a softer one once he appears on screen. The softer music continues as the ship destroys more rebel ships. This was actually fairly easy to do and just needs some minor tweaking.
4.) Finally there is a scene between Jynn and Cassian walking on the beach. In the middle, there is a short scene with Vader telling and officer to prepare a boarding party. Simply remove that part. But this is where it gets tricky.
The music changes dramatically from the beach shots and this one. Also, before we see Vader, the two are sitting on the beach. After the Vader scene, they are standing and hugging … so … it makes a transition of them sitting and hugging already tough enough along with a very different music cues … This is one where I need some ideas or some help.
As a side note back on point 2. We can simply remove either the whole dialogue or use parts of it about targeting the base. The reason is more of a logical/military thinking about it. The original dialogue established “Vader will take care of the fleet, we are taking care of the base.” By either removing the scene or adjusting the dialogue in some ways makes it “random” a SD comes out of nowhere. True, it may not be needed at all and we the audience assume a SD came to the rescue since an imperial base is under attack!
I will play around with this, I admit I MAY be tempted to keep it the way it is or the shortened dialogue.
