I’ve got an edit in the works right now using 4K HDR footage, currently at 3 hours and 37ish minutes.

Start with the Siege of Mandalore retro Lucasarts Logo
New Opening Crawl, merging the original RoTS crawl with text that summarizes Maul’s rescue in Son of Dathomir and Skywalker and Kenobi’s campaign on Yerbana, essentially keeping it as close to the context of the original Revenge of the Sith crawl as possible while simultaneously re-contextualizing when the film starts, then resuming with the normal episode’s opening. While having a narrator “and” a crawl is repetitive, I’m trying not to cut any footage out of RoTS or TCW itself in this edit, so I’m keeping it anyway. The episode continues until after Ashoka calls, followed by…
I’m including all 2003 microseries Coruscant bits, save the scene where Mace crushes Grievous’ chest. The edit starts immediately with Yoda noticing the attack. The rest of the first Siege of Mandalore Episode up to Ashoka’s departure is also intercut with these scenes, including a break between Anakin offering her a surprise, and the reveal of the Ashoka 501st troopers.
The scene where Mace contacts Anakin to tell him the Chancellor has been kidnapped is still included. My intention is that this is now the second time Mace contacts them, but the scene’s trimmed down so that it cuts straight to the call, Mace only mentions the Chancellor being kidnapped and not Coruscant being under Siege (they already know this, per TCW), the conversation about the vision on Nelvaan is gone, as is him repairing his arm, and recolors his scar back to the normal color as best I can.
The Siege of Mandalore’s opening battle is intercut with the opening RoTS Chancellor’s rescue. Maul encounters Ashoka and escapes the first time by the time Anakin and Kenobi reach Dooku/Palpatine.
Most of RoTS will be the canon 4K HDR version, save the inclusion of 4 (maybe 5) deleted scenes…

The Extended Constitutional Amendment/Office Scene (Captured through D+ 4K screen recording)
The 3 rebellion plotline scenes, including the 2 at Padme’s apartment, and the one in the Chancellor’s Office. All 3 scenes are placed directly where the original script specified they would be.
I may add the Degobah scene, but that honestly depends on how the arc ends. There are too many unknowns about the last 2 episodes right now. All 4 of these latter scenes use the Hal9000 upscales as a base with further processing to match the 4K HDR footage in both the film’s main color tone and quality as much as I reasonably can, while mostly preserving their original look.

The scene with Kenobi contacting Ashoka is right after the start of the battle of Kasshyyk, taking place in the same spot where Kenobi originally met with padme in the script’s deleted scene, the second Padme office apartment scene now follows this.
Maul capturing Jessie and interrogating Jessie up to his speech to his recruits is intercut with the start and middle of the Battle of Utapau ‘after’ Kenobi’s arrival.
The Petition of Two-Thousand Office scene follows Kenobi dropping his blade, as specified in the script, which is then followed by the rest of the 2nd Mandalore episode, ending Day 3 and starting Day 4. Because the trailer shows us remade footage of the “plot to destroy the Jedi” dialogue, I end the battle just before this scene, as it will likely be early in the 3rd episode, forcing the rest of the episode’s events to happen after this scene. While there is a bit of a chronology issue with just how ‘long’ Grievous was being chased by Kenobi, I think this order of scenes flows the best in the sense that it divides up multiple subplots in a way that feels cinematic, rather than just having a TV episode slapped in the middle of a movie, so this is what I’m sticking with as of now.

I’m pretty happy with what I have so far. I’ve played around with the non 4K/HDR footage enough to give it at least a light HDR touchup so that it all looks as reasonably decent as possible. Other goals with the last few episode include better intercutting the coming events with the current film Order 66 (if there are new scenes), and also trying to merge the end of the film and the end of the arc as closely as possible (again, if the ending events of the show allow it to fit with the film).

However, if scenes are depicted twice in TCW and in RoTS, I will likely cut the TCW bits so that the live action versions take priority, unless there is some clever way they can be spun together without being disruptive. Again, depends on how the last 2 episodes play out.

I’m hoping to share this next week and am considering posting a thread about it, but as I’m new, I’m not entirely sure how far I should/can go to share this.
