@patkhoo: What I did to find the balance in the movies was to take lots of frames from each movie, put them in photoshop beside each other in one big file, and let photoshop auto find the mid-balance of the greyscale.
Also, keep in mind that the movies were projected with warmer bulbs back in the day, as Mike Verta discussed in Harmy's thread. This would make them look more warm than the 70mm scans, which I bet were scanned using today's standards.
And this shot was just one of very many in that movie. Some shots still have a very cold feeling to them. The GOUT does not do a good job in representing the original color but I think we did the best we could to bring some of it back.
Ah, Gotcha! Were you using auto on levels or curves? Or both? I understand putting many frames into one big image, but would that be equivalent to finding the average of 10 when 3 are more like "X", 2 are closer to "Y" and the last 5 closer to "J"? I'm sure you considered this already, so what was the conclusion you came to? Related is, how was the previous (DVDv3) methods used (in comparison to this new method), which incidentally is clearly nowhere as good as this new method..
I'm not criticising the new approach, just trying to understand the rationale behind the methods used.
And now, for some fantasy.. I wonder.. (just wondering only)
The "auto-" capabilities in Lightroom are simpler to use than those in Photoshop. It is conceivable (damn near impossible with Photoshop, but maybe possible in Lightroom) to extract every single frame of the movie and adjust white balance, tint, saturation, vibrancy etc, for a "typical frame" in a schene, then apply the same settings in batch for all frames of the same scene. "Copy Metadata" and "Import profiles" are the key techs. Then Lightroom will batch render all frames to be recombined into a lossless AVI later. The fantastic thing is of course the fact that Lighhtroom does not make any changes to the actual image itself, only saving it in the DB, it is therefore possible to make changes to an individual scene (as opposed to a frame) as and when required.
In addition, the dirt removal tool is point and click for problem frames etc and advanced tools like unsharp mask, upscaling to 1080 etc are all a preset away to be applied on Lightroom's "Export" function. Heck, even the "dirt removal" tool can be batch applied to multiple shots in Lightroom..
Of course, let's see, a 120 min movie @ 30 frames/s = 12,960,000 frames. If there are 1000 scenes in a movie, then just manually adjust 1000 sample frames, and then batch apply to the remainder.. OK, it is fairly difficult, but not impossible. This may be the nearest practical method to the ultimate unthinkable of manually adjusting each and every frame in Photoshop...
Let me just say, it is merely a thought excercise, but I have Lightroom (and Photoshop), and I wonder ...
