Okay, I said I'd come back with a rundown of the various reasons (big and small) why the latest ESB:R clip is so fantastic, so here goes -
Shot of Falcon take-off - Falcon is a bit smaller in frame so that it seems to have taken-off from the middle of circular platform now. / A shadow underneath the Falcon has been added to the circular platform now / Landing gear retracts now. / Blue engine glow added now. / New sky and clouds added now. / New buildings which match SE additions now. / Lots of distant spacecraft activity added now.
Shot of first view of the 'Vane' - 3D effect 'zoom-in' now. / Altered-shaped 'Vane' with enlarged 'sphere' that's plausibly-scaled to contain the 'Carbon Chamber' now (the other unseen 'half' of the 'sphere' would equally jut out on the other side of the 'Vane', of course). / 2 vertical 'steam outlet pipes' added to 'sphere' now. / Window on side of 'Vane' is better scaled smaller now, and positioned nearer to front edge of it now, which matches with later 'close-ups' better. / 'Gantry' that Vader and Luke duel on has been shortened for better scale. / Front edge of 'Vane' widens gradually towards it's base now, which matches later 'close-ups' better. / An extra red light added under the middle of the 'Vane' base now, to match the 3 lights seen underneath it later on. / Unfinished bit of background detail on right of frame at start of shot added now. / A row of red 'vents' added all the way around background now. / A couple of tiny blinking yellow lights seen nearby the 'doorway' of the 'Vane' have been removed now, to better match the 'close-up' shots, where there were only blinking yellow lights on the top of the 'walkway' railings.
Shot of 1st 'close-up' of the 'Vane' as Luke enters doorway - Front of 'Vane' gets gradually wider below 'walkway' without a 'bend' in the structure now, in a way which properly matches the shape seen in the previous shot. / Window is moved higher and further back above 'walkway' now. / Additional yellow railing light added below window on left of frame now. / 'Dotted line' of background lights on bottom of frame (that are now white instead of orange) have been removed now, to match the fact that they should be lower down the chasm wall as seen in the previous shot. / Red 'vents' added in background to match position of ones seen in the previous shot now.
Vader and Luke's lightsabers are vibrantly re-rotoscoped throughout this sequence now (and the whole edit of course), with Vader's a satisfying RED instead of PINK, and now also include additional 'contact' glows when they clash together.
Shot of 2nd 'close-up' of the 'Vane' as Vader and Luke clash at doorway - Front of 'Vane' gets gradually wider below 'walkway' without a 'bend' in the structure here now, in a way which properly matches the shape seen in the first shot of the 'Vane'. / Window is moved higher above 'walkway' now. / Very bottom of 'sphere' containing 'Carbon Chamber' added above window now. / 'Walkway' at side of 'Vane' is extended past window to match how it looks in the first shot of the 'Vane' now. / 'Dotted line' of background lights on bottom of frame (that are now white instead of orange) have been removed here too now, to match the fact that they should be lower down the chasm wall as seen in the first shot of the 'Vane'. / Background wall details on the left of the frame are re-angled now, and the long vertical 'strip' seen in the first shot of the 'Vane' has been added, and we can also see the top tip of the 'stem' that attaches the 'Vane' to the long 'strip' here now too. / Hint of smoke added to railing now when Vader's lightsaber strikes it.
Shot of 'close-up' of Vader and Luke's clash at doorway - Railing is cut due to Vader's lightsaber strike now. / Hint of smoke added to cut railing. / Glowing scorchmark added near doorway due to Vader's 2nd lightsaber strike now.
Shot of overhead view of the duel - Background chasm wall is a lot more vibrant with more defined details now. / Bright outer glow around lightsabers which caused patchy edges against the matte background have been removed now, and we can see Vader and Luke much clearer overall. / 'Dotted line' of background lights below 'gantry' are uniformly orange all the way around now. / 'Gantry' steps and floor panels are visible now, instead of being hidden in darkness. / Bright reflective flashes light up the 'gantry' now when the lightsabers clash. / 'Rocket'-shaped section at the very end of the 'gantry' has been moved over a little to match it's position on the full-sized 'prop'. / Yellow railing lights glow brighter now, to match other shots. / 2 yellow railing lights that were missing beside the 3 posts that Vader slices through, have now been added. / Sparks that continue on for too long after Vader hits the railing on his left side are removed to match the other railing cuts now.
Shot of Vader slicing through 3 posts - The sliced posts have orange glows added to where they are sliced now. / Silver tape on the posts have now been blackened out now to better match how they look in later shots.
Shot of Luke's hand being cut off - Vader's lightsaber actually cuts through Luke's wrist now, rather than just hitting Luke's lightsaber hilt. / Luke's severed arm is shortened a little once hand is cut off, so that it doesn't seem too long anymore. / Red colour added to some 'missing'/darkened 'vents' on background now.
Vader's lightsaber is seen to retract at one point now, rather than being suddenly off in the next shot of Vader.
Blue light reflections on Vader and the sliced posts have been removed now, as there is no blue light source nearby.
In Luke's first 'close-up' as he hangs onto the very end of the 'gantry', his jacket doesn't stick out so far now, so that it doesn't look like he's hiding his not-really-cut-off-hand inside it.
Shot of chasm that Luke looks down at - Chasm backdrop has been 'flipped' upside-down now. / White lights and long vertical 'strip' that run down the side of the chasm have been re-positioned now.
1st shot of Luke falling down chasm - Chasm backdrop has been 'flipped' upside-down now. / White lights and long vertical 'strip' that run down the side of the chasm have been re-positioned now. / Luke is 'reversed' as he falls now, so that his correct hand is missing.
2nd shot of Luke falling down chasm - The 'Vane' is moved up further from our viewpoint now, and it's 'stem' now matches the length of the 'stem' seen in the first shot of the 'Vane'. / Extra white lights added to strip on chasm wall now. / Luke starts to fall further from our viewpoint now, and is 'reversed' as he falls now, so that his correct hand is missing.
...and all the above is wrapped in a far better re-colouration than the existing version too, of course.
PHEW! Tremendous stuff.
