Synopsis:
Thrilled by his experience with the Avengers, young Peter Parker returns home to live with his Aunt May. Under the watchful eye of mentor Tony Stark, Parker starts to embrace his newfound identity as Spider-Man. He also tries to return to his normal daily routine -- distracted by thoughts of proving himself to be more than just a friendly neighborhood superhero. Peter must soon put his powers to the test when the evil Vulture emerges to threaten everything that he holds dear.
Intentions:
There have been some beloved Homecoming edits out there, but so far, all of them (that I'm aware of) trim or recut moments of the film. I wanted to to a more by-the-numbers continuity-based edit; every change is made to service continuity or to extend the film, cutting (almost) nothing.
Change List:
Added 2012 date over Stark Tower
Replaced “8 Years Later” with “Present Day” (and re-created text effect)
Integrated a finished deleted scene by Ugo9p1
Added audio grain to match the theatrical version
Added SFX from the theatrical version throughout
Cut a shot with a blurred logo
Replaced two shots with blurred-out faces with the theatrical versions
Added in some SFX from the theatrical cut that weren't present in Ugo9p1's version
Added “A minor upgrade?” from the theatrical version
Replaced “Hey everyone” with Tony saying “Nice job, kid” to match Civil War
Cut a second from the beginning of the first Tony/Peter scene for a better transition
Changed Ferris Bueller audio to actual audio from the movie
Cut Karen describing Aaron Davis’ age as 33 (He’s actually 32)
Rescored Iron Man saving the ferry with the Iron Man 3 Theme
Cut "eight" from Toomes line "eight years and not a word from the feds."
Re-colored the Iron Spider Suit to closer match the version in later films
Added “The Definitive Edition” to the movie title card
Add Risinger Productions title card

Special Thanks:
A huge thanks to Ugo9p1 for creating his excellent extended intro sequence and for being kind enough to let me use it. His work is the real meat of my edit, and I probably wouldn't have bothered making it if it weren't for him.
Thanks to Bobson Dugnutt for inspiring a few changes in my edit, specifically the 2012 date and the Ferris Bueller audio. For a more trimmed FanFix, check out his edit Friendly Neighborhood Spider-Man; I've heard nothing but good things.
Thanks to u/Mo_Fro for explaining how I could go about fixing Toomes "Eight years" line.
