A thought... here you are the comparison between the italian Mondo BD and the 4K BD:

As you can see, Mondo BD used VC-1 @28000kbps while the 4K BD used AVC @23165kbps... even if VC-1 and AVC are not the same, they are in the same league - not like MPEG2, and so, how could a BD taken from a 4K master retain ALL the grain at about 23mbps is a mystery to me... I did a lot of tests myself, using REAL 35mm grain, and to retain ALL of it the bitrate should be over 30mbps...

With this, I don't say that Mondo BD, which has an higher bitrate, is automatically better than the 4K, but that *maybe* the former, even if used a 2K master, have the same, if not more, grain and details of the latter...

As I wrote before in this thread, inspecting two clips from both versions, it seems to me that the 4K BD has sometime less details in portions of the image, while a bit more in other portions in comparison to the Mondo BD, while this one has some compression artefacts, visible magnifing the still frame at least 4x... in motion, I have not noted high differences between editions, but again, they are two small clips that *may* not represent the entire movies...

I'd like to know your opinion about this.

P.S. Poita, you are great!
