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

Yeah. Sounds like something is going on there. No reason one should be better than the other, especially if you are sending the signal unprocessed from the Strato. But sounds like you’ve found something that works for you. Sorry to hear about your Lumagen issues. They can be finicky about setup and connection but if you are running an older JVC like it sounds like they can be a nice way to help with stuff like HDR and calibration.
 
I bought the Calman software to run the Lumagen CMS but it was rubbish. The free JVC calibration software without the Lumagen was way way way much better. And the Lumagen Radiance Pro would not pass audio bitstreams to the Krell processor, it would only pass LPCM. I'm going to have to revisit the JVC autocal and see if HDMI 1 input is independent of HDMI 2 input.

Sorry to hear you had issues. The CalMan stuff works great with Lumagen but there is a learning curve for sure. Also should be no issue at all with bitstream audio to your Krell. I calibrate and work with these all the time. Reach out if I can ever help out!
 
Lumagen needed a Krell processor to diagnose the audio issue but Krell would not come to the party. And I wasn't going to send mine two ways across the Pacific Ocean. Lumagen Support was great but I just ran out of patience with the Radiance Pro.
 
Do you guys think there be a K released without a hard drive down the road?
No, I think those days are over. There's so much more flexibility without requiring a server that I think even a small SSD should be standard on K Players from here on out.
 
My dealer is shipping mine out tomorrow via overnight UPS with Saturday delivery. For what that shipping cost me, it better show up on Saturday. Hopefully UPS is more reliable than FedEx has been.
Well... Apparently there is a major storm in the midwest. My Next Day Air with Saturday Delivery did not happen, and there has been no activity on the tracking number since very early Saturday morning. I am hoping, but doubting, I will get it tomorrow.

I'm in a similar boat. I'm half expecting the 100F temps this week to melt the K in its box prior to arrival. lol
 
Just purchased the Strato K and have a question…
I have a Sony A95L, it’s capable of the 4:4:4 chroma, but I believe it’s only capable in pc or game mode, in those modes the tv turns off its picture processing,
Anyone with this tv know what will be the best way to run the K Strato… and if I can’t run it in 4:4:4, will I be able to see a difference between the Strato K “cinematic” and my current Strato V ? Thank ya!!!
 
As @MikeKobb mentioned, reach out to Trinnov support. You might need a firmware update of the Trinnov´s HDMI board.
I meant open a support ticket with us. It would allow our team to look at the logs and see if we're getting bogus or inconsistent EDID information or something else that might be causing the problems getting a consistent 4K lock. Certainly wouldn't hurt to also make sure that the Trinnov is fully up-to-date.

I've ordered a Strato K.... [...] As I don't have a 4K AV processor I'm limited to 2CH LPCM for audio. The Strato C does not have that limitation.
I assume you mean because there's not a second HDMI audio-only output on the Strato K. This was unfortunately not possible for us to include due to a hardware limitation in the chipset. However, there are definitely ways around this with an appropriate HDMI splitter that can extract the audio and output it separately. It's a shame that you're not using the Radiance Pro anymore, because it explicitly supports this.

Yea, I went with you all first. Sent the details about 30 minutes ago as I assumed it wouldn't be reviewed until Monday anyways. Thanks Mike!

If a display can’t do 444 without turning off everything than I would not suggest 444 for the output. You would likely use 422. People really need to stop obsessing about the chroma space like it is a go or no go when it comes to any improvement. If it really required a perfect chroma space pass thru I would tell everyone to skip this completely. No matter what you are starting with a file that has more chroma information than before. Chroma is the thing in video we are the least sensitive to, so it is the thing that you should be the least worried about. I guarantee that in 99% of setups there are going to be chroma conversions, it is almost completely unavoidable. The great thing is, you are always starting with more chroma than you had before, so there is still a benefit. These files also have a lot more bit rate than before, so they should be even better from a detail perspective and shouldn’t have any issues with banding. So yes, there will be a benefit on paper for sure.

Jury is still out on how much any of these improvements will be subjectively. None of these things will hurt the video. But how much we will see the improvements from a seating distance with moving video is really hard to say. We were already chroma upscaling to 422/444 so how much difference there is between native and the scaling we had before, I don’t know. Again, we are not nearly as sensitive to chroma resolution as luma resolution. The upped bitrate may help with some titles but it isn’t like people were complaining much about compression issues or banding. At the end of the day you will know you have the best starting point of anything out there objectively, but how much visible improvement it will deliver is still up for debate. Some seem to be pretty thrilled with it so far.

The Radiance Pro would not pass lossless audio bitstreams, but ultimately I got rid of it because I was sick of the blue screen of death resulting from input switching or resolution changes, which then required me to mess with cables and restarting devices and standing on one leg or my head with fingers crossed hoping to get a picture back up on my screen. It was not worth the trouble. I'm planning on buying the Co-Star...I'm not sure how that would play with another device to strip out the audio to send to the Krell.

I had yet to see any 4:4:4 content (and I've been looking) but all the 4K_C content I've watched so far has been DV outside of Bohemian Rhapsody (HDR10). Not surprising that DV has all been 4:2:2 (which is still a great combo) but in the interest of looking into how my Sony Bravia 9 II might react when fed 4:4:4 content I downloaded Sinners in SDR. I figured maybe SDR would the land of 4:4:4 but no...Sinners 4K_C in SDR is still 4:2:2. Has anyone found any 4:4:4 content in the store?

BTW...I'm expecting my Sony to present an awesome picture when fed 4:4:4 content...just like 4:2:2...just like 4:2:0. 😏 I would think those of us with a Strato K directly feeding a modern flat panel should have the least worries of all Strato K owners.

In the settings, are you using allow display changes (with external scaler) or just allow display changes with the Bravia?
 
Hello! New member here.

This morning I had the opportunity to spend an hour with a couple of the sales guys at my local dealer's showroom. In their largest theater, they have set it up so they can alternate between a Strato C and a Strato K. Other components of the system in this 11.4.4 theater include a Trinnov Altitude 16, madVR Envy Extreme Mk2, Sony VPL-XW7000ES projector with Panamorph lens, and a Stewart Filmscreen StudioTek 186" screen. So far they have only downloaded 3 movies in cinematic format: Top Gun Maverick, The Greatest Showman, and F1, so these were the ones we compared. I did not ask them to download any others, because of the long download time (I really wanted to see some scenes in Project Hail Mary... oh well). But they were able to play sections of these three movies using the C, then the same content using the K. We selected scenes we are very familiar with, and went from the C to the K and then sometimes back to the C with that same scene to verify what we THOUGHT we saw.

I agree with the insightful and positive comments that have been made in this thread by other reviewers. I will share my impressions below. Caveat: I am not anywhere near as technical as others in this forum, and I am probably not able to provide any deeper or more technical information than what you see here.

General comments:
- We discovered that it wasn't extremely productive to watch items that were moving rapidly (planes flying, heads turning, helmets moving) when trying to see the difference between images. What worked better for us was to focus on more stationary items, such as background scenery like trees and mountains. We felt that there was significantly more detail visible in the sky (e.g. cloud formations) in the K image. Also, certain colors, specifically yellows and greens, seemed more vivid in the K image.
- Someone (grettagirl, I think) commented earlier in this thread that when you pause, the picture is very clear. I agree, especially when you pause on a quiet scene (i.e. where there is little movement).

Movie-specific comments:
- In Top Gun Maverick, we thought the sky, trees, and mountains looked incredible during the mission sequence. We noticed small but wonderful details in the interior of the planes, such as scratches on the aircraft canopy, that the 3 of us agreed we had never noticed before (despite having seen this movie NUMEROUS times). Screens filmed inside dark rooms had great contrast, and facial features were very clear even in the darkest scenes. In the scene where Maverick and Penny are sailing, the colors of the water and sky, and the blue sail, were absolutely beautiful. Jaw dropped. Seriously.
- In The Greatest Showman, we selected a scene near the beginning of the movie where the children are on the beach. I felt like I could have counted the hairs on the blond girl's head, it was SO CLEAR. Clothing detail was incredible. We then picked the scene with the song "Never Enough". The contrast of the white gown with the actress's skin, makeup, and red hair, against the background... the scruff on Hugh Jackman's face... everything in that scene was so clear and just jumped off the screen.
- F1 was a movie I had not seen yet, but the others had. We watched a scene where the driver made a pit stop and they got him in and out of the pit in under 3 seconds (that boggles my mind even more than the images I saw). The shine on the car exterior, the detail on the stickers on the car, and even the TIRES looked incredible.

I definitely agree with those who have said if you watch a scene in cinematic format on the K, then you watch the same scene in 4K, differences are readily apparent. There were a few times when I'd watch something on the C, then the K, and think "well, I THINK it's better", then go back to the C and say "oh yeah, NOW I get it!"

If you want to find yourself transported INTO a movie, this should do it for you. This was by far the most immersive movie experience I have had, outside of a huge IMAX theater.

In summary... AMAZE! AMAZE!! AMAZE!!!

The staff at the dealership felt that if you have a screen that is NOT acoustically transparent, you are MAY see a (very slightly) better picture than with a screen that IS acoustically transparent, like the one in their theater is. They felt that even when the holes in the screen are very tiny, there may be a very slight impact to the picture. I have no idea if this is true, so don't shoot the messenger here! I am only relaying what the guys at the dealership told me. They may have just been trying to encourage me, because my screen is NOT acoustically transparent.

They also said they have used the K with a "large" Samsung TV (I have no further details on the TV or other components in that setup) and they said the image was "spectacular".

I have a Strato C with a compact Terra server (22 TB), madVR Envy Extreme Mk2, Sony VPL-XW6100ES (Bravia 8) projector, with Panamorph lens, Trinnov Amplitude 16 and Trinnov Altitude 16, a 125" Stewart Cima screen, and a bevy of Bowers & Wilkins speakers. (See the home theater photo gallery.) Since the theater at the dealership also has many of these components in the video "chain", I am confident the K will work well in my theater. Maybe the visible improvements I saw today are more noticeable on the huge screen at the dealership than they will be in my theater with a smaller screen, but any improvement is a good thing. I guess I will find out soon!

They placed my order on Saturday June 20. We checked this morning (Thursday, June 25) and there is already a tracking number, so my K is on it's way! This is part of a larger upgrade (I am replacing/upgrading my in-wall and in-ceiling speakers and I added the K to that order, to replace my C), so I can hardly wait to experience all the goodness!

Thanks to everyone who is contributing to this thread. I am learning a lot from all of you!
This is just what I want to read. I too have a Sony 7000. And, what you're saying means I will have to contact my financial advisor, who will undoubtedly suck a lot of air in through his teeth. I will have to explain that unless I have one of these, my brain will explode, and that will be the end of his fees.
