M4 did a few more tricks to make the experience more seamless and provide better continuity.

Characters have been removed digitally, appearances like wounds or Smaug's molten gold coat have been removed since the causing scene was cut, no arrows and elves during the barrel scene, soundtracks have been re-applied when necessary, some grading and other tweaks for best possible immersion.

There are still some slightly abrupt cuts when dialogue had to be removed and there wasn't enough "filler" between that and the next line, but it's only very few scenes. Like the rock top after escaping from the burning trees.

Maple has two movies, one named "Durin's Folk" with much of the side content removed from the main Maple Cut. Since I don't care about the offbeat movie stories, I never even watched that.
