Ya that’s why the hdr-x version is so addictive. I can also see the difference on the OLED screen HDRx vs the normal HDR10 version from the studios
Somehow we tend to have preferences for these type of colour depth, they look so much more appealing to the eyes
I also noticed the red on the hdr-x version is always different, it has so much more depth in the reds…
But it’s good we all have a clue on what the reference looks like with the pictures from 20th century studios… at least we are on the right track and able to discern the difference between reference vs preference…
Think I figured it out. The 20th Century Fox shots were taken from the official trailer, which is in 4K SDR. That’s why the colors were less vibrant. As we know, the extension of colors for BT2020 over REC 709 are a lot in the greens and reds
Might be worth watching the 3D version in imax that uses Laser Pj, I think those 2D versions video on non laser PJ in the cinemas are quite poor. I think u might need to check which cinema shows 2D version using Laser PJ
I’ve been wanting to check out SDR video for this also, to see how it stacks up against hdr… but couldn’t find the source… now can get to compare
Would be good to see the difference on hdr-c vs SDR version on YouTube
One thing is certain, if one uses a SDR2020 calibrated version to play the SDR version from YouTube, the colours will surely be off. It’s already a challenge to get calibrated SDR709 to look similar….
Interesting… let me find out again tonight … SDR version vs 20th century studios… then we line them up again… hehe
709 and BT2020 simply point to different colors on the CIE chart, so if you try to play 709 content on a BT2020 calibrated display, you will get a red push and its quite obvious.
However, if you have MadVR in the chain like me and abhuj877, it will map 709 content into the correct colors for a BT2020 display and all will display correctly. So whether I play the HDR trailer or the SDR trailer on my SDR BT2020 calibrated LG HU810 mode, both will display with the correct colors, however the HDR trailer will have richer reds and greens, but remain accurate.
Most of my HD SDR content is TV and Sports. For that, I don’t need accurate colors, but prefer the picture to be more vibrant and punchy, even if the colors are not accurate. For most HD SDR content, I therefore bypass MadVR by switching the projectors HDMI input to one that is connected to the Vertex2 second output. However, are a also few 4K SDR (709) movies on Netflix and Amazon Prime. For those, I pass them through MadVR so that the colors are converted to BT2020 and the colors are accurate on the BT2020 display. I could tell MadVR not to do the conversion and output to one my my 709 calibrated modes, but haven’t seen much difference for movies.
If you don’t have a videoprocessor that can map 709 to BT2020, then you have to rely on the projector changing modes from SDR to HDR, where SDR is calibrated to 709 and HDR to BT2020.
The colors look very close, but different LG modes differ in brightness and contrast so overall picture is not identical. If you have, like me, seen 709 content output to a BT2020 display, there is a very obvious red push. It’s not a subtle difference.
Yup had been checking but it’s been quite hard to check which cinema is laser. There were announcements from GV & Shaw that the GV Paya Lebar and Shaw PLQ is an all laser cinema complex. So that’s the best bet i guess. Short of calling/emailing the cinemas up to ask.
Avoiding 3D cos my eyes cant really take long shows w 3D
Now that we know the Century reference is in SDR (likely SDR with a BT2020 colorspace), the skin color of the water tribe has vastly different tones. It leads me to think that since both are using BT2020 colorspace, what’s causing such a big color tone shift? Just look at the ornaments worn around the neck area, the hair colors, and dare I say, literally, everything looked vastly different!
We are no longer talking about PQ curve (or gamma 2.4 for SDR) or tone-mapping anymore, this is all about colors. The MadVR and Lumagen each sports a different color tones and shades, as were other OLED TV brands handling it. What are your thoughts, which one is true to the Director’s intent. If I were to ask J Cameron to give his opinion, which is faithful to his original intent, I wonder what he will say about the drastic difference in colors.
In fact, if I am to revisit the JVC N7 screencap (courtesy of Roni’s pal), I beginning to see some proximity in terms of the color reproduction matching the Century version despite being dismissed by many of us as having a “green push” effect.
My final thought on this is Avatar The Way of Water probably isn’t the best material to faithfully showcase HDR. Instead, we should focus on real-life material (e.g. nature, fire, water, landscape and “flesh tone”) to have a better gauge on the color fidelity in HDR.
, then you will need serious help with getting the colours to look decent on the display……
