I watched this last night and I would like to share some quick thoughts.
I thought is was great. There were a few small things, but overall it was a good effort.
A couple of observations:
When Luke first gets the lightsaber from Obi-Wan, he turns it on and then there is a weird kind of halo or distortion around his arm. I assumed that is ws from the roto-scoping, but I am not 100% sure. I did not notice it elsewhere when sabers were used.
There was a bit of an odd cut at 52.00 minutes when dick nose is perusing the group to the Falcon. I can’t remember if it was the same in the Blu ray; I will have to check it out.
Also, there did seem to be a bit of a drop off in resolition in the Mos Eisley scene. I know that you said you upscaled that scene and I did not mind it, as I prefer it to the SE version. Maybe a tinker with the upscale settings can make it more seemless if desired.
As far as the SE parts, the only ones you used that I still don’t like are the one scene with the Storm Troopers riding those weird beasties when they first land abd begin searching foe the droids and the scene with R2 hiding behind the rock. The CGI in both of those scenes is not very good compared to the practical effects, but the other SE scenes were not as noticable.
I think it helped that I just watched the Despecialized edition and the changes doc a few days before.
Overall, it was a really good effort. It sounded great on my soundbar and looked good, color and resolution wise on my tv, 4K Panasonic. Thanks again for letting preview it.
