You may want to think and find a common thing for these two events which may be different than in your normal shooting situations. Like solving a crime scene. Did you use a camera bag with some electronic device with magnetic field or things with sharp edges , did you do something new and specific with these two cameras. Do you have some sharp metallic edges in your coat which may damage LCD when hanging in neck. Have you red the manual trouble shooting. Can you reproduce this issue with some old camera. What may generally cause white pixels in LCD. Try googling the issue.

AF confirmation is not a single frame like a photo taken and recorded, it's in simple terms like checking the status of a pixel or pixel area (I.e. what does the pixel see).

This makes sense. The sensor in video is illuminated all the time and the rolling shutter picks lines for video frame. The camera still sees the sensor all the time and can pick other than actual video frame data and with different speed and area. I thought the camera analyses only the video data. Thanks.

Contrast analysis has nothing to do with fps. It is a separated task and in many cameras there is a dedicated chip for this. This is like bonding fps with EVF's refresh rate. Different things.
But there is no other sensor for AF. How a sensor can read different fps for video and for AF. What if the shutter angle is 360, it uses the whole time exposing video frame.

in return this would mean the camera shots 480 FPS and it doesn't. It does 9 FPS but reads the sensor still 480 times for AF confirmation.
So why shouldn't the GH5 shoot photos at 4K resolution at 24/30/50/60 FPS and still reads the sensor at 480 times?
B
With photos the camera reads sensor differently before final exposure. It may read only the focus box area very fast or with lower resolution or with less color for DFD AF.
In video the sensor works in some frame rate and I dont think it does different reading modes between video frames for AF. I dont know it for sure but if someone knows better it would be nice to hear. I may be wrong. Seems still that GH4 and GH5 auto focuses faster at 60P than at 24P at same resolution.

gh5: 480 times a second and each frame
-> it's 40 vs 480 times a Second for AF confirmation.
The GH5 is the first Pana that has the next generation DFD built in.
Yes in photos but in VIDEO:
24P - 24 AF samples/second
30P - 30 AF samples/second
60P - 60 AF samples/second

Color balance is way off, skin tones awful; just because someone's doing a test doesn't relieve them of the responsibility of making half-way interesting content.
I think this video is for stabilization comparison, not for skin tones. The scene has very difficult lights, yellow low sun and sky blue everywhere in snow and shadows. What is right or good skin tone in the first place? People generally has very different skin colors. This GH5 video shows quite low dynamic range but it is maybe poor due to settings.

Well, check out my latest to videos on vimeo on your TV. bahamas was shot in 4k, hoge veluwe in 1080p - do you see the night and day difference?
The difference is quite big but the GX85 fullhd is also good. You have lots of movement and soft backgrounds so the resolution difference is not visible all the time. I shoot a lot static or slow moving sharp nature clips so the clean resolution shows better.

I did. Like I said, the 4k image is spellbinding, but so is the 1080p image. And since no one sits like 1 meter away from his 65" TV, why even bothering? Heck, my audience doesnt see it, so why should I care? These are questions I am asking myself.
My GH4 1080P video looks soft and ugly compared to GH4 4k in my 65 inch 4k TV. Is the GX80 fullhd better than GH4 fullhd?

Yesterday I watched my more recent videos on my brothers 65" 4K TV,... I dont really know whether I would be able to spot the 4k content vs 1080p content from the GX80.
You must watch closer because the difference is like night and day.

I think the coming (summer) GH5 Hybrid log gamma profile uses h.265 4k 10bit. I hope it works in 4k 60P too.

...using aperture or shutter priority as well as Program mode, will result in the loss of zebras as soon as you adjust exposure via the EV route, not aperture or shutter speed. As I had mentioned, this behavior doesn't occur with Sonys.
Panasonic seems to have a policy to hide or block exposure information when shooting with auto exposure. User must guess what the camera is doing and only at home we figure something has been wrong.

Is 6K available at 16:9 aspect?..i think it's for 4:3...
It is 1:1, 4:3 or 3:2. I wonder why 16:9 is not possible. 3:2 is good for post stabilization and post cropping.

Yeah but how many seconds can you shoot it?
The whole day if I want. With several memory cards and GH5 two hot swappable mem card slots.

I've shot with a few Sony cameras ( both consumer and professional ) over the past 10 years, and the Sony IPB encoded footage has never looked as good as the Panasonic equivalent. Which is why I'm not worried about Panasonic 4K 10-bit 4:2:2 footage encoded at 150 Mbps."
Something to think about.
GH5 18 Mpixel 10bit 200Mbs HEVC video has twice the efficiency compared to h.264. So it has 3-4 times more video image data than 4K 10-bit 4:2:2.

Can someone test how much better the 6k photo video is compared to normal (4k only) modes? Is the AF working properly with 6k photo video? Is the NR as good as in 4k video?

Any way to to use the AF/AE button as a start/stop in video mode? Also, anyway to use the AF/AE button as a BBF in manual mode? I cant find any info on this.
It would be nice if Panasonic would give more freedom to assign favorite functions to FN buttons. Why not make all the menu items available for FN buttons? Every menu item should have an option to save to FN-button when browsing camera menus. It would be easier to program FN buttons.

Can't be true. I don't know how it works, but you must be able to set the ISO before enabling the feature that changes ISO when zooming with a variable aperture lens. If not, like you say, it's sad and disappointing. And I would go so far as to say useless.
Edit: it's quite amusing in my opinion to read the comments in your post about this topic over at DPReview. One commenter writes:
The basic Auto ISO implemtation sucks, but I got the G85 anyway, and I quickly got used to setting aperture, shutter and iso manually.
He set them manually! Fucking amazing! I'm not making fun of you, but setting aperture, shutter speed and ISO on the G85 is a piece of cake.
Setting everything manually is fine and a way to get exactly what a user wants. It works well in Panasonics.
If someone wants to use automatic exposure (i.e. auto iso) it is not nice when Panasonic is making life harder by blocking exposure information. It is not always possible to use full manual but I still want to know roughly what is happening. Anyway I will be shooting with 6k photo 30P video and when using 4k 60P the exposure is not so critical compared to 30P.
edit:
"....feature that changes ISO when zooming with a variable aperture .... "
Obviously it works only with auto iso and then you cant know what current iso is.

Can we presume that if you're shooting at ISO 200 and zoom in from 12mm f/2.8 to 60mm f/4 that the ISO will change to 400? I don't find that so disturbing. Though it would be cool to see the ISO values changing displayed on the LCD, it is constantly changing, so I don't see the inconvenience. It's only one stop after all.
The point is that you cant know if the iso is iso200 or iso3200 in the first place.

Nice feature for event shooters and run & gun: auto ISO seems to compensate for non-constant aperture in the 12-60 2.8-4
It is sad and disturbing that GH5 does not show auto iso value. It would be nice to see what iso the camera chooses. Fortunately GH5 can shoot video with 6k photo. It shows exposure information and iso reading all the time.

OK...let me create a shitstorm...all this crap about color science is fucking exhausting...so I'll say....in a camera choice, for me, I prefer Panasonic as more color accurate...I don't want a camera or a computer or a fucking iPhone to create colors that are NOT in front of me and make me think what an incredible photographer I am...it's an easy cheat IMO...I prefer to start with an accurate WB and have a colorist do what I need....in post....
I like Panasonic colors with Natural profile at low iso. When raising iso the noise makes image unpleasant and dirty. Colors fade too. GH5 iso100 will be very welcome because even GH4 iso200 has some times too much noise. I use always NR -5. Panasonic realistic colors works very well with a high contrast high gamut 4k TV.
Canon colors are not always realistic, they are like "candy" colors.

I hope someone tests GH5 5k 10bit video.

One user says Panasonic G-cameras (G7, G80, GX80 etc) has different 4k 100Mbs codec than GH4. Any opinions?

Does the current FW version show exposure info in GH5 EVF or screen in all video modes? First prototypes dont show exposure info (aperture, shutter speed and auto iso) in all video modes other than full manual.
Panasonic GH5 - all is revealed!

Maybe Panasonic is doing last fixes to FW so that the GH5 could show exposure info in video modes
