This film copy has a single problem. It’s a combined copy. 2 in 1. When you play at the projector on a large screen, everything is fine, but as you scan it, there are differences. It’s a shame but the copy is in good shape. Sorry my english but I use google translator 😦
It is very hard to get an accurate representation of a theatrical print in HD video because of color space and dynamic range limitations. HD video simply doesn’t have the range, so a lot of tweaking must be done to squeeze the range in. HDR video goes a long way towards getting us much closer, but it is a ways off from widespread adoption (if it ever is).
Can you tell me any more about the scan? Was it done in RAW format? Do you have any video samples?
