Create list of items from 1977 which are still M.I.A.

The DIFF project can help explore the sources for the 2019 variations.

Some shots are reframed. These are assumed to be a rescan from the original negative or at the least a piece of film. (the latest probably from the 97SE) Some of these rescanned shots have a slight different square pixel ratio. For example a shot might have the same left frame edge relationship to something in the frame but the right side is expanded, yet is contained in the same overall frame width.
Some shots have the same framing almost exact. These are assumed to be not rescanned from a piece of film but Lucasfilm went back to a digital source when starting to 4K the shot. [but this is not completely true found some shots which deviate from this logic, the Aurebesh addition or DS explosion for example]
Are there things which might help identify when a change which was done for the 3D conversion?

All times are approximate, but once the deviation is determined should be added or subtracted from the rest to whatever timeline you are working with.

~0:17:52 - Halo around Owen’s head removed

~0:19:41 - Reel 1 fade length is different.

~0:21:08 - In 2019, as part of the 3D conversion to add depth, the color of the far background and top sail of the Sky Hopper have been recolored. (this is the first shot in the Leia Hologram scene)

~0:26:56 - In 2019, the recolored sky has left some very clean edges around Luke and 3po’s face.

~0:27:46 - In 2019, the Landspeeder shots were digitally recomposited again?

~0:32:04 - In 2019, they added a pan to Luke finding 3po’s arm.

~0:42:43 - In 2019, Group looking at Mos Eisley is partially zoomed in. As this shot is part of wipe, the next shot, landspeeder entering Mos Eisley, is also zoomed in.

~0:45:06 - In 2019, Wide cantina shot, there is an odd brightening near Bo Shek.

~0:45:33 - In 2019, Wide shot Luke and 3po entering cantina, Luke’s head has been brightened at the beginning of the shot. General halo glow.

~0:49:19 - Close up of Ben an example of a shifted shot

~0:51:16 - Odd brightness halo…

~0:52:12 - In 2019, additional two engine space craft seen moving (up and right) in the right side opening at the beginning of the shot.

~0:52:38 - In 2019, the iris wipe to the Jabba scene has been redone. Softened. Possibly lasts one frame longer.

~0:54:10 - In 2019, the right to left wipe out of the Jabba scene was redone. End of wipe is the same but starts at a different point, compare when the wipe crosses Boba and 3po.

~0:55:22 - In 2019, shot of Han (close up) shooting back at stormtroopers while running into the Falcon is frame shifted to the right more than other reframing in the 2019 variation.

~0:56:12 - Matte lines around Star Destroyers

~0:56:14 - Luke’s hair in and out of blue screen

~1:01:17 - In 2019, this shot (Han close up watching Luke with lightsaber) was shift right. Hypothesis to remove some of the far distance part of the shot to reduce 3D depth work.

~1:04:44 - In 2019, one frame of this shot, out the Falcon window of the Death Star, is a composite of two frames.

~1:12:46 - In 2019, Shot shifted left, Stormtrooper Han and Luke walk Chewie following two Imperial Officers. On far right, previous 4 wall light panels, in 2019 there are now 5.

~1:13:01 - Pulsing of lights in the Death Star matte painting still do not pulse as they did in 1977 as trio waits for elevator to Detention Center.

~1:14:09 - In 2019, shot is pulled back. First shot of Imperial Officers in Detention Center.

~1:17:13 - In 2019, shot is reframed left. Chewie then pan to Han, get behind me.

Could this reframing issue be related to the ‘A’ and ‘B’ roll of the original negative? or is this irrelevant, since the scan was done from separation masters which might not have been the ‘A’ and ‘B’ rolls?

~1:21:45 - In 2019, when Chewie pushes against the compactor walls, the bottom of frame used to have a red bleeding from onset over lighting, this has been revised to a black fade.

~1:26:41 - In 20019, shot reframed left, when Ben’s is deactivating the tractor beam.

~1:29:09 - In 2019, the background matte painting of hanging objects has been recolored to match others as Luke and Leia swing across the chasm. Three shots.

~1:30:26 - In 2019, Lightsaber flashes, figure out if they were recomped for the 4K or is it just a rescan.

~1:32:20 - In 2019, shot reframed left to center Obi before Vader cuts him down.

~1:34:24 - In 2019, an additional frame jog occurs early in this shot which has fake shake. The later fake shake is that same as 2004. The early shake/jog is a new 2019 change. Similar thing done to both Han and Luke shots. Last frame of Luke shot is purposefully shifted.

~1:34:51 - In 2019, Han, in the last frame of this shot is altered. The background panning stops and Han continues to move but differently than previous versions.

~1:35:20 - In 2019, Han, in the last frame of this shot is altered. The background panning stops and Han continues to move. Second case.
Note: is this some 3D perception trick?

~1:35:22 - In 2019, Han, in the last frame of this shot is altered. The background panning stops and Han continues to move. Third case.

~1:35:24 - In 2019, Last frame of the shot the background remains where it is while Luke continues to move. In the past the background moved. Fourth case.

~1:35:27 - In 2019, the first frame of Luke ‘I got him!’ shot is warped differently than previous variations. Fifth case.

~1:35:44 - In 2019, the first frame of Han has a different framing than previous version. Sixth case.

doubleofive : in the Digital Bits article the ~1:35:48 shot of the approaching Tie fighter (page 6) the 77 and 11 screen shots might be from a shot a few shots earlier which has the tie fighter still off center in 2019.

~1:35:49 - In 2019, The first three frames of shit Luke shot have been reframed, then the shot returns to a similar location seen in previous variations. Seventh case.

~1:35:56 - In 2019, the first two frames of this Han shot have been reframed, then the shot returns to a similar location seen in previous variations. Eighth case.

~1:37:22 - In 2019, Artificial reframing pan happens over the first 10 - 15 frames, when Leia leaves and Luke talks to Han about her.

~1:37:52 - In 2019, Shot reframed with a pan early in the shot, then returns to previous variation location.

~1:37:57 - In 2019, Shot, Luke, reframed with a pan, could this be a byproduct of some stabilization?

~1:37:58 - In 2019, Shot, Han, reframed with a pan, could this be a byproduct of some stabilization?

~1:38:32 - In 2019, the live action portion of the overall Rebel Base shot flexes differently that previous variations. Probably just a re-scanning issue.

~1:38:37 - In 2019, shot contains more left of frame, Rebel Hangar.

~1:46:05 - In 2019, beginning of shot contains a slight shifting possibly due to a stabilization effort. Luke’s head moved semi-independently?

Are shots which match exactly a sign of shots which were redone at a certain point in time and they did not go back to original negative or some pieces of film. Question if that break point is the 1997 or the 2004.

~1:47:07 - In 2019, Blue Leader is reshifted for the first few frames, then realigns with earlier variations of this shot.

~1:47:22 - In 2019, Porkins is reshifted for the first few frames, then realigns with earlier variations of this shot.

~1:48:43 - In 2019, Luke cockpit shot and next special effect shot are shift left.

~1:49:34 - In 2019, last frame of Vader in Tie Cockpit, shifts differently than previous variations. This seems like an automation process which because it doesn’t have another frame to analyze makes some determination which places things a few pixels differently.

~1:50:24 - In 2019, garbage mattes return to Humdinger Glitch shot. Maybe they don’t show using the correct HDR.

~1:55:09 - In 2019, Luke’s head moves differently than the background for the last frame of this cockpit shot.

In 2019, the credit rescan moved them a bit, there is a vertical aspect ratio affect. In the center of the frame things align but above and below they stretch.
