theSUBVERSIVE

When these cameras were not out yet, a few years back, I thought that Panasonic should pack video-feats in the G9 just like upcoming GH5.
At the time I though the GH5 would be something like the GH5s but with IBIS, so it would offer better low-light like the A7S line up, better rolling shutter and readout speed but the G9 could still offer compatible V-log L capabilities to work as a B-cam for video. That way, you could have higher-res pics with the G9 and better video with the GH5 and they would complement each other pretty nicely, in a similar way Sony does.
In the end the G9 didn't get the video-feats - well, until now -, the G9 and GH5 ended up sharing the same 20MP sensor and there was a separated GH5s with better low light, multi-aspect sensor and no IBIS.
Panasonic has backed down from the early promise of 8K by 2020 for the GH6, they showed their 8K camera with organic sensor, but from what I've read, it's a power hungry sensor, so it doesn't look like the technology is quite ready for consumers cameras. Will the GH6 or G10 come with ToF AF?
 
G10:
higher MP count IBIS reliable continuous AF for sports high-speed and high-capacity buffer maybe dual-gain circuit if they can 4K 10-bit GH6: 
new 20-ish MP sensor dual-gain IBIS 240+fps slow-mo maybe 4K90p or 120p? 4K60p 10-bit internally  reliable AF without hunting/pulsing in video S1H's hinge/fully articulated screen at least the same RAW recording as the S1H It seems like a reasonable list, the major doubts are the new sensors and ToF AF or PDAF, but if Panasonic can pull that off, they will be a pretty good pair for photo, video and hybrid shooters, enough to keep the Micro4/3 interesting without disrupting their S-series.

There is no option to bake LUT into the footage - for now. But hopefully if enough people ask for it, there will be. I've asked around and this is something some of the Lumix ambassadors were also talking with Panasonic.
As far as I know for now, all you can do is to convert a LUT to Varicam .vlt and use it, the function is called V-log L View Assist and it only works in V-log L and although it would be very interesting if Panasonic could open that option for other picture profiles, I doubt they will.
But the ability to select, preview and bake a LUT in-camera would be very useful and welcomed.

Yeah, these were almost exactly my comments there. C5D does far too often technical mistakes like this, it happens in basically every article. They look more knowledgeable than they actually are and I've seen this in so many articles, enough so I follow the news, but take any technical report with a grain of salt.
They are confusing compression issues with color depth issues, two very distinctive things, propagating terrible misinformation for those that know even less than they do.
To clear this up, they should have done an external recording to rule out compression and codec issues before jumping into 10-bit is no good. Plus, I'm not really into this level of pixel peeping anyway. They even missed some other observations about the other cameras artifacts or even other GH5's advantages too.
In the end, they are spreading a lot of misinformation which will only confuse even more people that already don't eff understand what color depth and chroma subsampling is, this is already a complicated topic to discuss out there because there are already a lot of poorly done tests about this matter and this isn't doing it any favor at all.

Interesting, I've been looking for someone with enough knowledge of HEVC to ask a few questions, so if you have the time, I would appreciate. But before that, from what I've read, VP9 wasn't really as efficient as HEVC, being closer to AVC than HEVC but I don't know how much it has improved since then.
Does HEVC have All-I encoding or just IPB? If it has All-I, how much less tasking would it be compared to the usual IPB? Is there advantages of having an All-I H.265 encoding?
I fully understand that NLEs and computers haven't caught up with HEVC yet but since Panasonic GH5 is already capable of encoding it, I don't see why it shouldn't have H.265 for 4K as well, even if RIGHT NOW most people wouldn't be able to take fully advantage of that.
Well, simply because some people would and as time passes, more and more people would, H.265 is after all the codec of the future and having a camera like a GH5, that is already making some splashes, using HEVC, that by itself would help the industry move forward faster since it would help creating a demand for that. Otherwise we will be stuck and simply waiting for Manufacturers and Software to start supporting whenever the feel like and since there is not much demand, why would that be a priority for them?
So even if I can't personally take full advantage of HEVC now I would like Panasonic to think forward and implement it, if Photo 6K already uses it and if Anamorphic Hi-Res will also use it, I can't see why they couldn't be able to implement it for 4K or even create a 5K video mode. 6:9 5K is 4800px and DCI would be 5120px - which is why this is much more like Photo 5K than Photo 6K, what an unnecessary marketing BS.
Anyway, I'm all for pushing technology forward. C'mon Panasonic, just give people the option to record in H.265 10-bit 422 - since Photo 6K seems to be 10-bit 420 for now.

But it also says 10-bit 420, so it doesn't look like it's 10-bit 422 for now.
I know it's not MJPEG but I based my arguments on AVC codecs we have. Sony offers XAVC-I 480Mbps for 4K48p and Panasonic offers AVC Ultra 640Mbps for 4K48p, sure it's possible to get it by 400Mbps and still have a good quality, but it doens't look like Panasonic is going to do that. Following the chart and getting 400Mbps All-I 10-bit 422 kind of confirms to me that Panasonic is following similar specs to what they already have in the AVC Ultra, they probably will just change the wrapper.
Sure it's still in pre-production but there is not much open to interpretation about the chart. You just follow the lines and you get 4K48p 150Mbps 8-bit 420, the yellow highlight is simply to say what's coming via FW.

For the multi-aspect ratio discussion, it doesn't look like one at all. Everything looks like standard Micro4/3 sensor, I think that ship has sailed.
As for the 400Mbps All-I comment I made before. Two of the guys that shot the GH5 promo videos replied back saying that although there is nothing official, they think that the 400Mbps All-I is indeed H.265 and NOT H.264. Nick Driftwood also replied back since I tried to confirm what he said during the Live Q&A and he said "it would HAVE to be h265 I believe :-) dont you?!".
When I wrote about wanting H.265 as an additional option I thought Panasonic wasn't really bold enough to pull it off but since the GH5 already have the HEVC encoders and these guys think the firmware update will bring H.265 400Mbps All-I, although there is nothing official about it, I don't doubt it will be indeed HEVC.

On the H.265 and HEVC topic and 400Mbps:
I was assuming that 400Mbps All-I is H.264 but there is nowhere saying which codec is it and when I asked Nick Driftwood on a Live they did on Facebook, he said like the 400Mbps codec was actually H.265 and it would be equivalent to a 800Mbps in GH4 since HEVC has about half the size of AVC.
I'm not sure if he made a mistake but that what he said.
That's something I wrote about some time ago and that it would be interesting to have H.265 All-I version for the GH5, so if it's true and the GH5 is providing both H.264 and H.265 codecs, that's very interesting and quite future oriented approach.

Photo 6K uses H.265 as its base codec and 4K50p/60p 8-bit 420 also uses HEVC.
I wonder if HEVC will come to other 4K modes and if an All-I flavor of H.265 will also come later with the 400 Mbps firmware update or is it the 400Mbps already H.265?
The later firmware update will also add high-resolution Anamorphic Video Mode and Hybrid Log Gamma for 4K HDR Video (for playback on HDR compatible televisions).
Does that mean REC.2020 is also coming?

hahaha... who are you?
I like people challenging this idea because it makes me think deeper to see if there are hole in my reasoning and what makes more sense. I quite neutral when it comes to logic because I disregard my personal wishes and try to tackle it simply by what makes more sense or what could be a reasonable proposal.
In this case, if you read the press release, in summary it says that Photo 6K is a more advanced Photo 4K and it's basically the same thing but with higher resolution.  And most ideas outside of that always fall into complicated plots and compromises when I think that multi-aspect sensor can easily solve everything. And more often than not, the simpler solution is usually the more likely scenario.
If you think about it, Photo 4K in the LX100, which uses a sensor acting like multi-aspect sensor, it gives you the max resolution of each aspect ratio. If you apply that to this possible GH5, then you get 20+MP for 4:3, 19-20MP for 3:2 and 18-19MP for 16:9. If you assume Panasonic will make improvements over tracking AF, then you basically get a full sensor readout 30 fps burst with tracking AF, which is more than the E-M1 II offer with C-AF at 18fps, the difference is that the GH5 will output JPEG and the E-M1 II will output RAW as well, oh and that supposedly 30fps of JPEGs can be sustained for longer, like mentioned in the press "long-time burst shooting capability".
I'm speculating that in a Panasonic and Olympus deal, Panasonic got 10-bit 422 and 4K 60fps while Olympus got full sensor readout RAW output and one can't have the exclusive the other has. Photo 6K comes from video, so it's like a workaround to get the full sensor readout burst without getting too close to Olympus' exclusive feat. I also think that Olympus helped Panasonic with IBIS and Panasonic helped Olympus with video encoding technology, because I find very weird that Olympus will all of sudden offer this 200mbps All-I 1080p codec that only Panasonic has been using until now.
I wrote all of that in all these articles but I wrote too much, most people don't read it! hahaha... I just wanted to get it out of my head and put somewhere and hopefully get into some discussions and think different stuff, see some new perspective and keep learning.
 
 

Apparently you agree with everything I said then because I also think Panasonic was very clear to what Photo 6K means.
I wrote that "I also countered the idea of Panasonic straight out deceiving consumers". Because I received some response to my article of people saying exactly that, that Panasonic couldn't possibly achieve Photo 6K and that it was just marketing mumble jumble to deceive consumers. If you read the article about the multi-aspect sensor you will understand it better.
What seems to happen is that a lot of people are misinterpreting Panasonic's press in a odd way but if you put everything together, this other interpretation doesn't make sense.
People are reading like this:
“6K PHOTO” is a high speed burst shooting function that cuts 4:3 or 3:2 still images out of a 18-megapixel (Approx.6000 x 3000effective pixel count) video footage that 6K image manages.
So they think that it will be 4:3 or 3:2 images out of a 18MP video footage and they are ignoring the 6000 x 3000px reference.
This is what one person said to me:
"With a full sensor readout of a 20MP sensor, you can store 4:3 or 3:2 pictures with 30fps in a non standard video format. Because this 4:3 or 3:2 video format has approximately the same pixel count as 6k video they call it 6k."
Some other people said that multi-aspect didn't make any sense and that they expected a 25+MP sensor.
Anyway, I was just addressing what people that don't agree with multi-aspect sensor has been saying.

I wrote 5 articles speculating about the GH5, talking about possible codecs, what else can we expect but the most intriguing part is obviously the Photo 6K.
Actually, from Photo 6K you can speculate about the sensor as well. In summary my conclusion is that it will be a multi-aspect sensor.
Panasonic GH5: the Sensor has to be multi-aspect!
My best guess is a 22+MP multi-aspect sensor, possibly based on DCI (1.8x crop) instead of 16:9 (1.85x crop*) for a bit more than 5760px wide and a Micro4/3 area of 20MP, possibly the same pixels size and count than Olympus E-M1 MK II.
*we usually say 1.86x crop but if you do the math, it's much closer to 1.85x, but let's not get lost in technicalities because that's not the point and nor that important
If Photo 4K has that name based on UHD at 3840 x 2160, then we could expect Photo 6K to be something around the 6K version of 16:9, so 5760 x 3240px.
On Panasonic's press release, it says that Photo 6K is 18MP (6000 x 3000px) still grabs from video footage - which is a generic way to say it will have a video-like aspect ratio. But they also mention that the source of the video can either be 4:3 or 3:2, which is quite weird. Why wouldn't Panasonic even mention 3:2 as the video source? This is a clearly indication of full sensor readout, but why 3:2?
The 16:9 multi-aspect sensor used in the GH1 and GH2 are almost 3:2 and a DCI based multi-aspect is 3:2, for me, this is another argument that it might be multi-aspect, otherwise, I don't understand why being a 4/3 sensor Panasonic would mention 3:2 aspect ratio as a full readout video source for Photo 6K.
But why did they mention 4:3 then? Simply because they didn't want to confirm multi-aspect sensor, wouldn't people start asking themselves why a video from a 3:2? There is a possibility of Panasonic using a 4:3 of 25MP to 28MP? Of course there is, it's just very unlikely.
More importantly, there were rumors saying it was going to be multi-aspect and also rumors saying 20MP. But why 20MP? Because the Micro4/3 portion of the sensor is 20MP, just like the GH2 was called a 16MP camera, when in fact it had more than that for the whole sensor. Plus, because part of the sensor is outside the image circle, the max resolution you get with the GH2 is indeed 16MP in 4:3, 15MP in 3:2, 14MP in 16:9 and 11MP in 1:1, therefore a 16MP camera.
I said that the 20MP portion could have exact same pixel count as Olympus because I suspect they were developed together, the same way the E-M5 and GH3 had the same sensor, E-M1 and GH4 and also GX8 and Pen-F. It makes sense for the E-M1 MK II and GH5 to be based on the same sensor tech, plus, there were also rumors about Panasonic and Olympus sharing technology and even LSI components. Having the same pixel count and size, it's possible to share the sensor wafer, micro lens, color filter, etc. it saves you production cost money because you can both use the same parts, just different sized sensors.
The greatest thing of multi-aspect sensors is that for lenses, nothing changes since it's all within the same image circle, so you can either use native lenses or focal reducers like Speed Booster without worrying about the extra FOV of the multi-aspect sensor. So yeah, when using the 0.64x Speed Booster, you could get less than 1.2x crop, even closer to 1.15x crop with the Speed Booster and multi-aspect sensor combo. I would still prefer less crop to use APS-C lenses like the Sigma 18-35mm f/1.8 and 50-100mm f/1.8, even more with IBIS, but for those wanting the 1.33 extra stop of light and closer to FF, then the 0.64x will get you pretty close to FF.
Again, this is my best guess:
22+MP multi-aspect sensor DCI based (approx. 1.8x crop) or 16:9 based (approx. 1.85x crop) at least 5760px wide, probably a few pixels more to accommodate DCI 4K and Photo 6K the Micro4/3 portion and max resolution of the camera will be 20+MP, so the GH5 will be a "20+MP camera" 20+MP will be possibly the same pixel count and size as the E-M1 II I also wrote about other possibilities including other resolutions like 6114px or even the scenarios of not choosing a multi-aspect sensor. Just like I also countered the idea of Panasonic straight out deceiving consumers with nothing like 6K in Photo 6K but just 18MP, which I find kind of odd since there is no need to Panasonic to deceive consumers and they haven't done anything like that ever before. Photo 6K is not the main feat of the GH5, it's 10-bit 422 and 4K 60fps, why mention 6000 x 3000px if they were simply going for 30fps full sensor burst?
There is always that possibility, but logically speaking that has to be less likely than going back to the GH line up roots of multi-aspect sensor. I mean, this line up was developed with multi-aspect in mind from the get go. But sure, this is still just speculation, but I like the odds of a multi-aspect sensor.
If anyone is interesting in getting more in-depth about this, you can read the other articles.
I think that the article about codecs or ProRes/DNxHR is also pretty interesting, even more for those wanting those codecs. My conclusion is that it's better to buy a proper 4K recorder with SSD than buying expensive high-speed UHS-II cards for such high bit rate, I don't think Panasonic would leave their trump card for just a few people that can afford that - the high-speed UHS-II would cost more than the GH5 or several GH5s).

It's worth noting that the E-M1 II full announcement is quite imminent and giving that the E-M1 II will have the same 200mbps Full HD All-I codec as Panasonic already use, the full specs of the E-M1 might gives a few hints about whether or not Panasonic and Olympus are really partnering up or how deep they are sharing and developing technology, and of course, hints about the GH5 as well.
Anyway, this topic is about those wanting to really get in-depth about the speculation and possibilities of the upcoming GH5.

My best guess is a 22+MP multi-aspect sensor, possibly based on DCI (1.8x crop) instead of 16:9 (1.85x crop*) for a bit more than 5760px wide and a Micro4/3 area of 20MP, possibly the same pixels size and count than Olympus E-M1 MK II.
*we usually say 1.86x crop but if you do the math, it's much closer to 1.85x, but let's not get lost in technicalities because that's not the point and nor that important
If Photo 4K has that name based on UHD at 3840 x 2160, then we could expect Photo 6K to be something around the 6K version of 16:9, so 5760 x 3240px.
On Panasonic's press release, it says that Photo 6K is 18MP (6000 x 3000px) still grabs from video footage - which is a generic way to say it will have a video-like aspect ratio. But they also mention that the source of the video can either be 4:3 or 3:2, which is quite weird. Why wouldn't Panasonic even mention 3:2 as the video source? This is a clearly indication of full sensor readout, but why 3:2?
The 16:9 multi-aspect sensor used in the GH1 and GH2 are almost 3:2 and a DCI based multi-aspect is 3:2, for me, this is another argument that it might be multi-aspect, otherwise, I don't understand why being a 4/3 sensor Panasonic would mention 3:2 aspect ratio as a full readout video source for Photo 6K.
But why did they mention 4:3 then? Simply because they didn't want to confirm multi-aspect sensor, wouldn't people start asking themselves why a video from a 3:2? There is a possibility of Panasonic using a 4:3 of 25MP to 28MP? Of course there is, it's just very unlikely.
More importantly, there were rumors saying it was going to be multi-aspect and also rumors saying 20MP. But why 20MP? Because the Micro4/3 portion of the sensor is 20MP, just like the GH2 was called a 16MP camera, when in fact it had more than that for the whole sensor. Plus, because part of the sensor is outside the image circle, the max resolution you get with the GH2 is indeed 16MP in 4:3, 15MP in 3:2, 14MP in 16:9 and 11MP in 1:1, therefore a 16MP camera.
I said that the 20MP portion could have exact same pixel count as Olympus because I suspect they were developed together, the same way the E-M5 and GH3 had the same sensor, E-M1 and GH4 and also GX8 and Pen-F. It makes sense for the E-M1 MK II and GH5 to be based on the same sensor tech, plus, there were also rumors about Panasonic and Olympus sharing technology and even LSI components. Having the same pixel count and size, it's possible to share the sensor wafer, micro lens, color filter, etc. it saves you production cost money because you can both use the same parts, just different sized sensors.
The greatest thing of multi-aspect sensors is that for lenses, nothing changes since it's all within the same image circle, so you can either use native lenses or focal reducers like Speed Booster without worrying about the extra FOV of the multi-aspect sensor. So yeah, when using the 0.64x Speed Booster, you could get less than 1.2x crop, even closer to 1.15x crop with the Speed Booster and multi-aspect sensor combo. I would still prefer less crop to use APS-C lenses like the Sigma 18-35mm f/1.8 and 50-100mm f/1.8, even more with IBIS, but for those wanting the 1.33 extra stop of light and closer to FF, then the 0.64x will get you pretty close to FF.
Again, this is my best guess:
22+MP multi-aspect sensor DCI based (approx. 1.8x crop) or 16:9 based (approx. 1.85x crop) at least 5760px wide, probably a few pixels more to accommodate DCI 4K and Photo 6K the Micro4/3 portion and max resolution of the camera will be 20+MP, so the GH5 will be a "20+MP camera" 20+MP will be possibly the same pixel count and size as the E-M1 II I also wrote about other possibilities including other resolutions like 6114px or even the scenarios of not choosing a multi-aspect sensor. Just like I also countered the idea of Panasonic straight out deceiving consumers with nothing like 6K in Photo 6K but just 18MP, which I find kind of odd since there is no need to Panasonic to deceive consumers and they haven't done anything like that ever before. Photo 6K is not the main feat of the GH5, it's 10-bit 422 and 4K 60fps, why mention 6000 x 3000px if they were simply going for 30fps full sensor burst?
There is always that possibility, but logically speaking that has to be less likely than going back to the GH line up roots of multi-aspect sensor. I mean, this line up was developed with multi-aspect in mind from the get go. But sure, this is still just speculation, but I like the odds of a multi-aspect sensor.
If anyone is interesting in getting more in-depth about this, you can read the other articles.
I think that the article about codecs or ProRes/DNxHR is also pretty interesting, even more for those wanting those codecs. My conclusion is that it's better to buy a proper 4K recorder with SSD than buying expensive high-speed UHS-II cards for such high bit rate, I don't think Panasonic would leave their trump card for just a few people that can afford that - the high-speed UHS-II would cost more than the GH5 or several GH5s).

It's worth noting that the E-M1 II full announcement is quite imminent and giving that the E-M1 II will have the same 200mbps Full HD All-I codec as Panasonic already use, the full specs of the E-M1 might gives a few hints about whether or not Panasonic and Olympus are really partnering up or how deep they are sharing and developing technology, and of course, hints about the GH5 as well.
Anyway, this topic is about those wanting to really get in-depth about the speculation and possibilities of the upcoming GH5.

I wrote 5 articles speculating about the GH5, talking about possible codecs, what else can we expect but the most intriguing part is obviously the Photo 6K.
