I just got my SnowWhite Blu today and watched the new BatB Diamond Edition trailer right away. Now, let me start by saying that my mom has seen this movie many times both my old VHS and the DVD (though only 3-4 times on the DVD on our old TV before we got the HD TV).
About 10 seconds into the trailer she was like "What's wrong with that picture? It's so bright and cartoonish. Where are the shadows".
And I have to say myself, I was a little shocked at how different the trailer looked, even from the DVD, and not in a good way.
(I was especially shocked at how Lumière looked, he was bright bright yellow and not with a little golden tint as I though he is supposed to be)
To make my point in response to nomad2010 I also think that the IMAX version was brightened to go better with the giant screen and I remember reading an interview with Kirk Wise from when the IMAX version came out and the mentioned how they did not only add detail to the background (like for example putting faces on the Beast and Belle when Lumière and the others are watching them during their snow fight), but also correct lines in the animation. According to Wise when they first tested BatB on an IMAX screen back in 2000 or 2001 some of the thicker animation lines looked like "telephone polls" on the huge screen. So they went back and corrected those lines, i.e. making them thinner.
Of course, if you use that print for a DVD the thinner lines basically disappear on the way smaller TV screens thus giving the impression that somehow depth has been lost, because all those lines that create a style and shadows are so thin they are too small to be seen on the small screen.
However that does not yet address the color issue yet. But I think that might be a reason why the IMAX print on the DVD looks so weird to some of us.
I guess they adjusted the print too much for the IMAX screen and I guess they also used that for the new Diamond Edition trailer. They usually use unrestored or stuff from previous restorations/prints for their trailers.
Now, for the new Diamond Edition, I really hope they will only use the original CAPS files for the print that don't actually need any restoration because they are digital and that this will result in the right colors and right depth of the picture with all the lines and shadows as they were originally drawn.
I guess the best solution would be to put the original CAPS files print on Disc 1, together with the work-in-progress version using seamless branching since those two are basically the same movie.
And then the IMAX print with the new scene on Disc 2.
Make Disc 3 all bonus features and voilà a perfect Diamond set for BatB
And carrying over all the stuff from the previous PE would be nice, like all the TV spots and the original Dion/Bryson music video, the art galleries...
Here's also a link to the interview I was referring to:
