I'd thought I'd bring it up to you knowledgable guys.
When I saw Superman Returns in IMAX, I noticed what I can only characterize stairstepping artifacts (I hope I'm putting this correctly) that I would normally associate with video.
It's especially noticeable by me during the opening credits that mimic the opening credits of the original Superman movie. I could see the lines in the moving credits shimmer a bit and behave as if they were being shown on a (high quality and huge) high definition video display.
It was undeniably projected on film but it was as if the film was recorded from High Definition video files that show some seams on the huge IMAX screen.
I've noticed this before, watching the entirely computer generated movie "Robots" in IMAX.
However, I never noticed it on "The Polar Express" in 3D IMAX which is also computer generated.
Is it just that films scanned from high definition files just will show these seams on the huge IMAX screen or is it that it's more expensive to scan it to Imax film in a way that will never show these artifacts.
I enjoyed the film BTW
