DIF - 2004 vs 2019

Star Wars Episode VI Return of the Jedi

Change Playback Speed : Full Speed : Half Speed : Quarter Speed : Eighth Speed : Sixteenth Speed

Note: Playback will not be instantaneous, please be patient. There is no audio. Video is highly compressed and will contain many artifacts.

Note : Insert Here.

Questions : Would like to better understand the color reprocessing which was undertaken in 2004 and determine how much of that correction was carried over into 2019 and what was left out or not reapplied.

All times are approximate.

Let us know of things you find.

0:00:29 - In 2019, the 'Star Wars' zooms into the distance higher in the frame. The crawl follow this higher location. To compensate the pan down to the moon of Endor is changed, just at the end, to get to the same resting point before the Star Destroyer flys over.

0:02:30 - In 2019, the brightness on the back of the left Imperial Pilot was removed.

0:05:38 - In 2019, R2's head has been stabilized to control where the head sensor is looking at camera.

0:12:45 - In 2019, Shot of Jabba has been reframed and has a different pixel aspect ratio. Loss of half of background character on the left.

0.13.26 - Why does this shot of Max Reebo return almost the same colors. Note: scan to a similar shot a few images later which has a different DIF result.

0.14.22 - Example of 2004 color modification. Was this a selective power window?

0.14.52 - The right side of this shot shows alignment in the DIF, but the left side is significantly unaligned. This would typically be a sign of a scaled shot. But if you compare to a similar shot... see next image.

0.15.00 - This shot is almost identical yet it does not suffer from the previous images reprocessing. Anyone got a theory why?

0.15.59 - Compare this Max Reebo DIF image with the example shown previously. Why do similar shots produce different DIF results? Does one shot contain a reprocessing in 2004, or would both 2004 and 2019 have something done or redone or because the DIF results are leaning towards black, could this be an example of a 2004 image which didn't get recolored?

0.22.46 - In 2011, they added a Dug walking down the stairs.

0.23.17 - Example of a scaled shot. Left side was held, right side flexes.

0.25.52 - Example of 2004 re-colorization.

0:31:35 - In 2019, power window around 3po in window of the Barge was removed or added?

0:32:40 - In 2019, power window around 3po in window of the Barge was removed or added?

0:33:21 - In 2019, Battle on skiff was zoomed out.

0:33:32 - Reframed shot of Boba which pans to Lando hanging off skiff.

0:34:03 - Example of blown out white of 2004.

0.35.37 - In 2011 this sequence was shifted by one frame. Affects the next series of shots.

0:48:26 - In 2019, Special Effects fix of a missing space ship in the upper right and the left side which was cropped was extended to fix the rounded frame corner which left part of the ship black.

1.12.51 - Example of the 2011 Ewok eyelid addition.

1:18:16 - In 2019, power window of the incoming light has been removed, when Leia goes to console Luke.

1.45.18 - The lightsaber clash explosion right before the infamous Emperor oddity from 2004, looks like maybe their judgement was to do this color change because the raw explosion was viewed as too much clear bright white at the time. As this has been undone in 2019, you can see how some detailing of these bright explosions has been lost.

1.47.10 - In 2019, exploding speeder bike changed to fit with the HDR process.

2:00:37 - Revised Vader demask shots. Shots are zoomed out.

2:05:26 - Fade to Cloud City has been modified. Cloud City is zoomed in. - Wipe to Tatooine has been retimed/redone. - In the transition to Theed, the last thin post gets thicker as it moved center to right edge. - Pan down to Ewok village follows same zoomed in framing as the SE added shots. Credits are shifted left.
