NEWS: Strato K Movie Player with 8K capability and new "4K Cinematic" full-chroma & higher bitrate support

Was scheduled to get mine around 10AM-2PM today but...

🤬

Last scan was Santa Rosa NM around lunchtime today. I'm sure FedEx will figure it out overnight. 😳

Oh...I sent in my first requests: Total Recall (2012) and Battle Los Angeles. Figured if they could do "The Tourist" they could get me a couple of my favorite old school 4K's in cinematic!
That’s near me, they should ship it here, by accident. 😀
 
Yes, any Envy can handle 4:4:4.

EDIT: Let me add some more info to that. In the following a quote from the developer from back early 2022. The Envy does full 4:4:4 processing since the very beginning:
"Pipeline bitdepth is an interesting topic. A pipeline can use either integer or floating point math, and you can have a pipeline in either 4:2:2 or 4:4:4, and you can count bitdepth either per component or per pixel. Envy's pipeline is full 4:4:4, from start to finish. If the input signal is 4:2:2 or 4:2:0, Envy always upscales chroma to 4:4:4 in the first step, usually using AI chroma upscaling. If you want to see some bitdepth per pixel numbers, here you go:

8bit per component 4:2:2 = 16bit per pixel
10bit per component 4:2:2 = 20bit per pixel
12bit per component 4:2:2 = 24bit per pixel
16bit per component 4:2:2 = 32bit per pixel
16bit per component 4:4:4 = 48bit per pixel (Envy temporary buffers)
32bit per component 4:4:4 = 96bit per pixel (Envy calculations)

It could be argued that the bitdepth only needs to be high enough to not introduce any banding (or other) artifacts, so maybe Envy is going overboard here. But that's just the native bitdepth Direct3D GPUs are working in, so it doesn't cost us anything. Now if you'd ask me how many bits a video processing pipeline needs to have, I don't really know. But surely it doesn't hurt to be on the safe side."
Great info all around here. One thing to add. People need to be aware that the entire chain is part of this. Many AVR/SSPs will convert the chroma of the sources they are switching; especially if the end user has any of their OSD stuff enabled for seeing volume and such. Then you have to consider what the display is going to do with it. A lot of projectors do their processing internally at 422. Ultimately what matters the most is the fact that the ORIGINAL chroma resolution is higher than it was before. Since it sounds like the vast majority of these titles are going to 422, not 444, almost any playback chain will work fine. Only acception may be if you are using Marantz/Denon with OSD displaying as I believe they use RGB, which may cause issues. Obviously debatable how much you’d see any of this but at some point it will be interesting to do side by sides. Easy to show differences with test patterns with this stuff, but hard to say with actual moving video. We’ve always been upscaling chroma since the K players always output either 422 or 444, so it is whether the native chroma actually looks different subjectively than the upscale. Interesting question given that we are far less sensitive to chroma than we are luma.
 
Running a MadVR Extreme MK2 with JVC NZ9 (soon to be Christie Mk25). Even though the MK2 has 2.0 HDMI input, on paper there seems to be no reason to upgrade to the MK3 (I am not a gamer). Does anyone have real world experience with this? Seems like the MK2 can handle the Strato K????
 
I have heard anecdotal stories of the MK3 giving a better image on regular 4k sources, Not sure why that would be.

If Billy Lynn's Long Halftime Walk ever becomes 4:4:4, then it won't work with the HDMI 2.0 input on the MK2. All other movies will work fine. Make sure the JVC NZ9 is set to bypass internal processing so that 4:4:4 is passed through untouched.

People need to stop jumping on the 444 marketing. It has already been stated the content is more likely to be 422 than 444. Also, turning off processing just to hope for 444 is likely giving up features/performance that is way likelier to have onscreen or real world benefit than preserving 444 from end to end.

I think that statement is in reference to DV titles. It also sounded like HDR10 and SDR offerings will match the assets provided by the studios (and those assets very well could be 4:4:4 with some regularity).
 
Most of the titles are DV only. Also, the last time I sat in a room with their engineering team I asked what their assets were delivered in. The response was 12 but 422 mezzanine files. So again. If I was a betting man the vast majority of these will be 422. We will never know though since they don’t list.

Yeah...very true that (at this point) it doesn't seem there will be many HDR10 (only) offerings in the store. SDR looks to be common though and revisiting the old "Mastered in 4K" era Sony/Columbia titles in 4K Cinematic SDR sounds like fun.

So the 12 part...as in HDR12 but 422? Makes sense if so. Once my K comes in today (FedEx found it!) I'm going to check to see if it the source signal information (chroma) changes from title to title in the web-based K config. Might actually tell us what's up with each title.

But, I tend to agree with you on your assessment of how hung up we really need to be on it. Signal chains will make the most of what they're fed. I'm not an LG guy but I definitely wouldn't be dropping into game mode. o_O

I know I saw this addressed somewhere in the past few days, but I can't remember the answer... Does the LRP or Artisan report on whether the incoming signal is 4:4:4, 4:2:2, or 4:2:0?

These files we play are not 12 bit, they are 10 bit. Mezzanine file is 12 bit.

Yes, they all report in the info page.

It has the required bandwidth/ headroom to do 4:4:4. Of course you’re not going to get content like that on a regular basis, but you now have the ability to support that if and when required. So I think it’s ok for folks to jump a bit.

E.g. I own a RAM TRX. Im not going to use all 700+ horses all the time, but it is good to know that it’s available at my disposal. Plus comes in handy to checkmate condescending bozos at the lights. 🤣🤣

You could always do 444 from the Strato, nothing has changed there. I’ve been using 444 with my Strato C the whole time as it seems to have less chroma delay than 422. The only thing that is different is how much upscaling is being used. Now you are either getting a full 444 file (unlikely) or you are only scaling from 422 to 444 of your output is set to 444.
 
Yes, they all report in the info page.
But that wouldn´t tell you the chroma of the content (which I believe was the reason behind the question), just what the Strato is outputting to the Lumagen, right? So if you set your Strato C to output 444, it would even now report 444.
