First of all, great work with this huge MCU edit, and thank you 3000. I´ve been looking for something like this for ages, i even made my own edit of the phase 1 movies a while back, but just didn´t have the right equipment to do it properly, so i applaud and thank you for such awesome work!!
There are some few adjustments you could make however. I made a comment about this a while back, but i guess it got lost somewhere.
In Ant-Man, more specifically part 14, at about 1:39:58, the image freezes - like the error you fixed with Iron Man - and never unfreeze again, until the movie is over. Also, at the end of part 14, the same scene from the opening of "Ant-Man and the Wasp" repeats itself.
Also, you have the scene where child Gamora meets Thanos for the first time, right after the Iron Man 3 opening scene, which takes place at new year 1999-2000. In Avengers: Infinity War, Thanos says to Gamora that she has told him she hated him "everyday, for almost 20 years". The year she stopped telling him that, was obviously the year she left him, which was 2014. Putting the Gamora scene after the Iron Man 3 scene, doesn´t really make sense to me, since it means Gamora has only been with Thanos for 14 years. It makes more sense putting the scene after Captain Marvel imo, which concludes in 1995, and putting the scene between 1995-2000 also fits better with the "almost 20 years" statement, since Thanos would probablt not have said "almost 20 years", when it has only been 14 years. Then "almost 15 years", would have been better and more accurate.
There were some other small adjustment, which other people mentioned in the lost comment section, but can´t remember them now :) Other than that, i greatly appriciate your work, and thx yet again!!
Also, there are a few deleted scenes from Incredible Hulk that may be useful to add; namely, there's an extended scene before Betty see's Bruce in the Restaurant.
There is also a whole collection of deleted scenes when Bruce is at Betty's house that better explain the story (in my opinion) and provide exposition about Betty/Bruce and Betty/new Boyfriend relationship.
It may also be useful to add the new daily bugle stuff, and the Spiderman: Homecoming promo's as they are kinda funny and add a bit more of spidey into the universe.
Happy to help if I can :)
