Some more good news on the upcoming firmware release. It appears that JVC new Frame Adapt HDR feature does not need static meta data (MaxCLL & MaxFALL) to work its magic because it is using its own proprietary algorithm to analyse each frame/scene to provide the best PQ. If this is indeed the case, then this is great for those with normal 4K Blu-ray player owners who don’t own an Oppo or Panasonic UB-820 player.

Rumours has it that the firmware to be dropped this week...likely from mid week onwards.

Yup. Seems like the best way is to just use a player to output as source direct. And then let the projector do it’s magic. Looks like no need for the Panasonic HDR Optimizer anymore, for those with JVC.

Haven't updated mine. Positive reviews from users so far. Fact that it is comparable to MadVR (which costs few thousands $$) speaks a lot on this free upgrade.  :o


(Google Translation)

FIRST COMPARISON: FRAME ADAPT HDR vs. MADVR

The weekend was over. A home cinema friend from Hamburg visited me. In the luggage a ready made ready made Media PC. Price: 3500, - Euro.
We wanted to find out how Frame Adapt HDR, which provides JVC as a firmware update for free (!), Can prove it in the A / B comparison.

Excerpts from the following films were used:
- Sully
- The Martian
- Tomb Raider

Preparation:
The JVC DLA-N7 was connected via an HDMI input. The image signals from the Media PC and Panasonic DP-UB9004 went first into the Marantz SR7011 and from there to the projector. The projector is calibrated, the color temperature is 6505 Kelvin (D65). Color is set to 10 to add a bit more brightness to the mottled colors without "bleeding out" in the films. HDR level (for Frame Adapt HDR) is high.
The Media PC was optimally adjusted according to the specifications of the dealer. No changes were made to that. In the Panasonic DP-UB9004 there were also slight adjustments in the picture menu, so that the sharpness was perfectly exploited on the basis of sharpness test images.
The projector has turned off all noise filters and blur.

All three films were previously ripped from the 4K Blu-ray from the Media PC and "read" via madVR. That took about 20 minutes per film. We did not use the live feature because the owner of the media PC did not use it.

First impressions of the picture:
Sully:
1. While the plane is flying over Central Park (Chapter 1), the paths are clearly visible on the snow. The sky offers a light blue course in the backlight. On the road between the skyscrapers, individual cars can be seen.
MadVR represents everything true to the original. Paths, gradient in the sky, cars. Everything seems very natural.
Frame Adapt HDR is in no way inferior here. Paths, gradient in the sky, cars. Everything looks very similar. Notable differences can not be seen here.

2. The plane hits the building. A flash explosion can be seen. In the background, the sun shines on a building and the blue sky can be seen behind it.
MadVR shows a very fine explosion. Sky and building elements are well differentiated.
Frame Adapt HDR is also no nakedness. However, the explosion seems a bit fuller. Sky and buildings in the background are also optimally differentiated.

3. Sully strolls through New York at night (Chapter 5). All around him are pictures and texts on all displays. The US flag shines in beautiful blue and red.
MadVR shows almost all the details here. The picture is crisp. Only the "Mitsubishi" logo outshines white. As Sully heads for a side street, there is a shadow of a building far away in the darkness.
Frame Adapt HDR brings out the flacons (back left) from the advertising a bit more detailed. Even the red of the US flag lights up a bit fuller. The blue lettering in the background is a trace blue. The Mitsubishi logo is completely displayed. The picture is as bright as from madVR. As Sully turns off towards Nebenstraße, the shadow in the dark background turns out to be clear as a building. Here, Frame Adapt HDR performs much better with the same black level.

The Martian
Already the beginning scene is a real touchstone, because the film no HDR metadata are stored. You can see behind Mars the slowly rising sun, a few lens flare effects and the flight over the surface of Mars. Later, the actors will be added. In the control room, two scientists monitor the work on the surface of Mars.
MadVR shows a really rich black in space. Individual stars are clearly visible. As the sun emerges behind the planet, the picture really shines magnificently. The surface of Mars is shown crisp, dark contents have a lot of drawing. The control room is of course mapped. Neon lights shine, skin colors look natural.
Frame Adapt HDR can do a better job. The black space is comparably dark, but there are significantly more small stars to see, which also shine (teilise) a trace brighter. The red on Mars is a less colorful and darker elements have significantly more drawing. At madVR, it is no doubt that details in black are drunk here. The control room also looks natural via Frame Adapt HDR. However, with Frame Adapt HDR, the hair of the scientist has more drawing. For the neon lights seem a bit darker.


Tomb Raider
Lara Croft is looking for her father. There is a lot of action and very warm filtered colors. Panoramic shots are crisp.
madVR also leaves a very good impression here. Of course, the colors look natural, the panorama shot of Hong Kong shows some small windows crisp. Unfortunately, there were repeated slight picture shakes in pans and turbulent scenes. When Lara signs the contract, a hoodie and a leather jacket run into each other in the shade. There is a little missing the tracing.
Frame Adapt HDR makes the colors seem a bit stronger. The panoramic view of Hong Kong looks similar. After repeated switching back and forth but shows that madVR still a touch appears sharper. If this was adjusted via the focus controller in Panasonic, this leads to slight double contours (white edges on high-contrast edges). Image jerking never occurred with the combination of Panasonic DP-UB9004 and JVC DLA-N7 with Frame Adapt HDR. Everything is reproduced very cleanly. Also, the shadow area in the contract signature is visibly better drawn. Hooded polo and leather jacket feature Frame Adapt HDR for all the details.

First conclusion:
The differences are extremely low at a very high level. Without direct A / B comparison, each of these films seems very natural.
It is noticeable that Frame Adapt HDR produces more drawing in both light and dark scenes, with the same black and identical maximum brightness. Moreover, the colors are a bit lighter and fuller.
Anyone who owns madVR can continue to use software and media PC on the JVC DLA-N7. If you're considering a new acquisition, you can opt for a lower-priced 4K Blu-ray player. With Frame Adapt HDR, any HDR-10 content can be optimally projected in real time. The long ripple and readout times (about 20 minutes) of madVR are eliminated. With Frame Adapt HDR, 4K Blu-ray movies as well as Netflix HDTV and Amazon Video HDR10 content can be played - virtually plug & play."


Pros and cons
+ minimal better sharpness with madVR
+ clearly visible better throughput with Frame Adapt HDR in bright and dark scenes with the same black level and maximum brightness
+ Somewhat brighter and brighter colors via Frame Adapt HDR

Exciting times ahead for me...I'm doing the update now as we speak. I will report with more findings and see if it is indeed that good. The fact that it is able to anlayze frame-by-frame and scene-by-scene w/o the need to rely on static meta-data is a huge upgrade!

Updating is a breeze. Took about 18mins.

Quick impression. Start up time seems a tad faster now. I will see whether the “iris pumping” which resulted in “yellowing” of white text/object against black/darker background has been improved with this latest iteration of the firmware.

Without saying too much...let the screenshots speak at this point. Pay attention to the details of the cloud (i.e. specular highlights) and the differences in color gradation (WCG) for the 2 different HDR processing modes - i.e. normal HDR (PQ) and the "new" Adaptive Frame HDR.

Frame Adapt HDR (On)


Normal HDR10 (HDR PQ On)


Frame Adapt HDR (On) - Cloud at close-up


Normal HDR10 (HDR PQ On) - Cloud at close-up


Frame Adapt HDR (On) - With Cinema Filter set to "Normal"


Frame Adapt HDR (On) - With Cinema Filter set to "Wide" (P3 colors)

Interestingly, the Adaptive Frame HDR processing mode disallowed JVC's very own calibration s/w from performing any kind of calibration. Is this a bug or intentional...Hmmm...

More testing to come...

- Playback some 4K UHD titles (physical disc)
- Playback using with and without Panny's HDR Optimizer (Kris Deering recommends to drop double processing - meaning use one or the other but not both)
- Playback 4K mkv files (with and without static metadata - MaxCLL/MaxFALL)
- Any difference between Frame-by-Frame and Scene-by-Scene - cursory checks shows almost negligible difference based on my 30 mins playback of the Samsung 4K footages
- Further testing required to see any "yellowing" from the "Iris-pumping" (need more testing at this point)
