Watched it! Smoothest Dune edit I’ve seen so far. I have a couple notes though:

There’s a handful of instances where the music buries some of the dialogue. I found this problem to be exclusive to the Extended Edition scenes.

1:00:46-48 looks choppy for some reason (as if the frame rate halved for those 2 seconds), and then the shots inserted from the window at 1:00:53-55 and 1:01:07-14 look very much like static stock images with a lack of dimension & motion blur. A shot of those respective landscapes but taken from a video source like you did from 1:01:39-46 would benefit greatly.

One slight thing I always thought could be easily improved from the original was the lack of VFX for gunfire from 1:19:52-57. Easiest way to take care of this problem is to add a white strobe frame for each gunshot with opacity varying between 30-60%, then up the contrast and lower brightness for the frame after each gunshot by about 20%.

There are also a couple shots from the original that I still think could be removed outright:

The obviously rubber worm at 1:05:09-11. The worm’s presence is much more effective just burrowing around below sand until the reveal at 1:06:20.
The soldier landing on a barely-disguised stunt mattress after being thrown off a bridge at 1:20:35.
Paul hanging on the worm in a hilariously bad matte extreme long shot from 2:01:08-11.

There’s probably some more shots that could be axed since they look less like they came out of high-budget 80’s sci-fi flick and more like it was done by that one perpetually-stoned slacker fired from ILM for pretending to animate Hipgnosis album art instead of, you know, working; but there’s only so much that could be done before the movie gets hacked to pieces (again).
