Actually, rather than wait, maybe you guys can help me find moments where the film gets blocky too. I highly recommend you compare the 1080p and 4K versions together so you can see the difference in change of bitrate, hence the blockiness. It’s also easier for me to start working once I arrive back home on Tuesday.
From what I read the 4K is a “completely botched encoding” and the 1080p is way better. Knowing that I don’t know why you would want to use the 4K at all.
There are only a couple moments I know where the bitrate goes from 50mbps to 192bps such as the Disney logo and when the Pizza Planet truck returns to its place. Though I do remember other unnoticeable parts with the bitrate changing to something like 10mbps like at 36:49-36:51 (though this is what I remember when I compared the two) so yeah, if no one is interested in doing it, that’s honestly fine. Though 4K was known to be a double of 1080p, so hopefully anyone might barely tell the difference.
