[request] Jurassic Park - 2DBD to 3DBD colours

[Turisu]

I watched the 3DBD over the weekend and I spotted something that I haven't seen mentioned elsewhere.

During the scene at the beginning of the movie where Hammond visits Grant and Sattler in their trailer and is talking about lawyers, the 3DBD is cropped so badly that Hammond is partially cut off by the right edge of the frame. At the point where he says "...they insist on outside opinions" a fake camera pan seems to have been added that gets Hammond back fully in shot. It looks as if the camera operator realised that Richard Attenborough wasn't in the correct position and then shifted the camera accordingly but, as far as I can tell, this pan is not present in any other release.

This raises the questions; why correct the framing mid-shot? And most importantly; why crop the movie so badly in the first place that you have to make digital alterations to compensate for it?

I guess this technically makes the 3DBD a pan-and-scan version.

spoRv, after viewing the 35mm scan, are you still interested in pursuing this project?

My view, after seeing how different a 35mm print looks, is that trying to make a home release look exactly like a 35mm print would not be easy nor do I think it would be desirable (with faded colours, black crush, blown-out whites etc.).

What I would love to see is a version that preserves the detail and saturation of the home releases but retains the 'spirit' of the 35mm print with darker night scenes and the same warm brown colour tone. In my opinion this is how a studio would handle the release if it was "done right" by trying to stay as close as possible to the look of the original film while retaining the detail present in the scan of the negative that is lost in the print.

I still believe the daytime scenes of the 3DBD represent a genuine (if imperfect) attempt to present a more saturated version of the theatrical colours. The night scenes on the 3DBD look dreadful though. Without the blue tint, the scene where Nedry meets the Dilophosaurus is obviously shot on a sound stage.

So is there still interest in creating a 'definitive' BD version of JP??

I still think it's a good idea.

I do too...

OK, it seems there is still some interest in this project... now that I've noted the film black crush, I opted to use WOWOW luma and process the chroma with the same automatic color matching script I used few posts back... here you are:

WARNING: as you can see, the frames are not exactly the same, because film version misses some near the end; but it could give you the idea of what the final color grading may be.

[TServo2049]

It's definitely a good start.

[spoRv]

I think so, too... but maybe the same results (if not better) could be achieved simply adjusting RGB (or YUV) levels... dunno if a single adjust could be used for the whole movie, though... any volunteer that would test this theory?

[Turisu]

It is a good start. The colours are looking better though still a bit too pink where it should be more brown. Also, is it just my imagination or are the regraded shots slightly brighter? The movie should definitely be darker in the shadows. The shot of the kids at the computer looks like it's in bright daylight. Only the 35mm makes it look like a dimly lit control room as it should be.

---

Here is a (very) quick and rough idea of what i think this shot should approximately look like. My tinkered shot is at the bottom. I think the darkness of the 35mm should be preserved as much as possible without losing detail in the shadows, and the greens need to be pushed towards brown while keeping the blues blue:

Never gave up with this project, but only put apart - as many others... so, I thought was time to resurrect this old thread, due to new color regrading technique and a bit of more knoledge.

Source: Canal+ HDTV open matte (with logo) as base, WOWOW HDTV 1.85:1 as main video overlaid to the previous
Color references: film scan open matte, 3D HDTV 1.85:1 (top/bottom) cropped and upscaled to fullscreen

Intermediate chroma: regraded source as film, regraded source as 3D
Intermediate luma: regraded source as film, regraded source as 3D, untouched source

Final chroma: the two intermediate chroma merge
Final luma: the three intermediate luma median

Note: chose to add also the source as luma, because in dark scenes final result using only film and 3D lead to too dark image, while using a median of the three, dark scenes are brightened a bit, while bright scenes have improved contrast; also, black crush and white clipping found on film are greatly reduced, if not deleted.

Test comparison, from top left:
film, regraded source -> film,
3D, regraded source -> 3D,
untouched source, final

Any chance you could send me the LUT for this one, so I could apply it to my 3D Blu-ray at some point in the future by doing this for each individual eye? Because I was hoping to do so in the hopes that I might use the resulting timing for the 3D recreation of the original theatrical trailer. In any case, this looks excellent.
