Mr. Stacey Spears is the expert. Me I'm just like you; a bit surprised too.
Oppo and Microsoft I just don't know if they can fix it...zero clue.

Both are looking at the issue now.

We have found a way to make Samsung players work, we believe. It requires making the static test patterns longer, which I am working on now. Nothing like redoing ~1000 files. Should be done by the end of the week. Hopefully we can go to replication next week.

On the plus side, I have used this time to improve four patterns that have been bothering me.

I see no alignment issues with the 1080p patterns on Spears & Munsil 2nd ed on the OPPO, one presumes these are issues that you're seeing with the 2160p chroma patterns on your nascent UHD disc? I've got other UHD test patterns (Mehanik, Masciola) and they don't seem to show any heavy-duty chroma issues, but then I've not put the same pattern up on two of my players at the same time for an A-B comparison.

PS

Please ask OPPO to implement the MaxCLL/MaxFALL metadata viewing that the Pannys can do!!

What does Chroma alignment issue means?

Laura’s apparently a legend also amongst creatures in the animal world ….

so I guess she lives a rich and fulfilling lifestyle outside of solely covering feature films, anyway, my feeling is that at least she doesn’t post pictures on social media giving the impression she knows what she’s talking about with regards to the filming of TG:M, like some other fans ->



sorry dude ^, although there are many reasons to love San Diego – https://forum.blu-ray.com/showthread...e#post16144287 that pic of Tom and Jennifer was not shot in San Diego, think more like on the coast about 120 miles north

I visited Notre-Dame de Paris in the summer of 1968 on a student tour. One could immediately sense the age and solemnity of the church upon entering through the front and eventually viewing the incredible rose windows. Can’t even remember all the religious and art treasures inside. And those flying buttresses on the exterior were feats of medieval engineering (and practical beauty).

Funny thing is that one story yesterday had photos from the past of the cathedral and one was an American student visitor in 1968 lighting a candle. I didn’t recognize her, but it made my hair stand up a little that it was the same year.

In 2020 they changed the chroma location from in between the luma samples (vertically) to co-sited with luma. So there is that delay. There is also a horizontal half pixel delay as well. This is with UHD HDR content. I think 709 UHD was okay, would need to check again.

I did ask OPPO if they can report player vs. display-led Dolby Vision. By default, it seems to go to player-led. You want display-led when possible. e.g. when plugged into an LG, force display-led otherwise you get player-led. Player-led is DV low latency mode.

I should add that some devices (player or display) also introduce half a pixel of delay when scaling HD to UHD. So we have added those markers on the scaling pattern too. We include both HD and UHD versions of the scaling pattern. So you can test 422 and 444 from your player in source direct vs. scaled and figure out the least destructive path.
