adywan, there's a couple of minor, strange 'glitches' on both the GOUT and the SE footage that I've never noticed before, until I looked closely at the 'chamber' scenes recently.

I don't know if you'll be able to do anything with this first one or not...but when Vader turns around from Needa, the sides of the frame 'distort' briefly when the 'viewscreen' comes on. The footage seems to 'bulge outwards' at the sides at this point, distorting the look of the wall detail momentarily...

It's not obvious in the 3rd shot below, and needs to be seen in motion...

And here's the second one. If you look past the 2 black 'prongs' of the 'chamber' nearest to us in the shot below, you'll see that a small portion of the white interior behind them seems to mysteriously move briefly. It happens at the point that the entrance door fully opens, then closes again...

Perhaps you can make this small white section remain static, before the shot begins to move?
