From CVP's over under testing the GH6 clearly does better then the GH5 and GH5S. The S1 and S1H also quickly get really bad horizontal banding when underexposed. To me those dynamic range numbers are kind of meaningless.

I see that with the DR Boost enabled, but not without, which seems to validate CineD.

Yes, so it looks like in DR Boost mode the GH6 can't match the S series cameras in the highlights (as you would expect from looking at Panasonic's VLog graph a few pages back) but the shadows are completely free from that awful horizontal banding which I was surprised to see on the S cameras. And the GH6 does amazingly well in colour fidelity underexposed (again in Boost)

From this test I think I'd be comfortable underexposing the GH6 in Boost mode by one stop to give an extra stop in the highlights when the scene requires it.

Underexposing is going to be tricky at ISO 2000.

And here I was thinking maybe the official version might not be in English?

"Odd" as in, new one by me.

I hear you.

Funny enough he's not the only one doing it.  I've seen someone else promoting their own live dissection of the event online too.  Not official though, I think they've just taken it upon themselves.

It's a very meta world now don't you know?  You might just have to get used to it 😉.

I thought this odd...

Why's it odd?  Not my cup of tea, but i imagine some people might find the official launch a bit dry and impenetrable, so he's thrust in front to make it a bit more lively and palatable.  Makes sense to me.

Is it not possible that Panasonic are also using a hardware solution based on the existing Dual ISO technology they have already used in the GH5S?

Actually... I'm just catching up on the rest of the thread that discusses things in more detail...

The Alexa sensor’s photosites have TWO ADC each, at different gain settings, in parallel, for simultaneous capture (at the same moment.) The signals from these offset sensitivity ADCs are then combined by the image processor to cover a resulting higher DR. This is entirely possible in a prosumer camera at reasonable bitrates via LOG scale encoding. The real bottleneck is the ADC tech, which is linear in nature. 
...

It sounds like the GH6 is using an entirely different approach to increase DR: sequential offset exposure.

Is it not possible that Panasonic are also using a hardware solution based on the existing Dual ISO technology they have already used in the GH5S?

I believe the ARRI and Canon DGO method is reading two gain circuits at the same time.

Kinda sounds like they are doing frame blending from a super fast readout.

I think the ARRI / Canon method is basically a frame blend too.  They've just done a much, much better job of marketing it!

It looks limited to 5.7K 30p. So 1900 mbps is about right... Prores 6K 422 HQ at 30p is 2121mpbs.

Yes, I was just looking it up myself.  I had C4K 30p at 943 mbps, so I guess the figure given is feasible.  Strewth!

I didn't realise the full specs were already shared.

Seems quite promising. I am curious about the autofocus, the dynamic range and low light improvements.

It's a leak / rumour / planted item.

Do people think this data rate is correct - 5.7K 30p Apple ProRes 422 HQ 1.9Gbps - seems awful high!

I was wondering when we would start to see this from Smartphones.

 

Isn't this extremely similar to how Canon DGO (or Arri equivalent) works?

-- just how well did the GH5 II sell anyway?

I imagine it sold pretty much as expected as it was designed to sell into an existing and identifiable market - people like me, who were interested in buying a new GH5 despite the imminent launch of the GH6.

I think the ticket is underexposing and boosting in post.

This seems to be becoming a bit of a strategy - utilising some of the excellent shadow rendition to make up for a perceived weakness in highlight roll-off.  Underexposing to retain the highlight data.

I would just think if the project is that important, why not spend the money and go with a more suited camera system? The Alexa's 444 ProRes files likely look much better and will save time and money in post. Maybe even the RED saves you money because of the editing speed.

End of the day... If you want the best image quality, you'll have to deal with a painful work flow. The joy of the Canon Cinema Cameras for me is the ease of use. All around.

I think the point is, if you've invested in a tool for everyday delivery, can you pull out the same device (with associated lenses, accessories, etc.) when you need to jump up in quality?
I appreciate your point, but not every project allows for a body hire like that.

Rumoured:

So RAW recording rumoured to be announced soon.  Do people think this will be a significant upgrade?  Any experience of C300iii RAW?

I think an open-letter video letter for Canon must be created, asking them not to do this. 

With DSLR I can frame shot with camera switched off (in sleep mode). This for me is great advantage, when taking landscape, cityscape shots. 

Mirrorless needs to be waked up each time. 

Andrew said Fuji are mirrorless, - yes, but Fuji have optical VF cameras!

I think you might have some difficulty getting them to turn around their corporate policy on that basis.  But you can give it a go.  You just have to find the other seven people around the world that feel strongly about that particular facility.

with the fast nvme now,odes it still have a sense to separate os/app from project files/cache ?

 ihave 1 tb nvme and i thought could be enough for all together in term of speed

I don't know enough about that to comment.

Ah, I see.

You need at least 2 hard drives and preferably 4 (or more).  The minimum recommended setup is:

Drive 1 - OS and NLE

Drive 2 - Project files, Scratch, & Media Cache

Drive 3 - Export and Storage

Some people further separate Project files and Scratch, etc.

GPU usage in Premiere is quite selective.  It can help with effects, render and export, but I don't think its going to impact your playback issues much (if at all).  CPU, multiple drive setup,  and overall system balance are the top considerations for Premiere.

Also, you will very often arrive at problems with h.264 and h.265 cut natively.  Much better to proxy or transcode to an editing format such as ProRes.  Even your proxies should be ProRes (or something similar like CineForm).

I'm not an expert in this, but one thing i have been gleaning from pro Canon users is that the official LUTs are not very good for some reason, and that highlight rendition is a particular area of concern.  Many people are using third party LUTs for input.

I  have been thinking about the increased processing, and the possibility of processing the video frames in camera.

Slow motion footage consists of monitoring frames at 24fps (for simplicity) when shot at a faster rate, if Panasonic (with their pixel binning experience) could drop frames but still produce a slow motion stream that could be monitored, streamed and maybe also recorded on an external ssd. Not sure if it's possible, but it would be a very impressive feature to monitor in slow motion, and open up some interesting creative potential 🙂   

Sounds like a complete waste of time.  Within seconds you'd be monitoring stuff that happened (in real life) seconds ago.  How would you even know where to point the camera?  Am I missing something here?

I just like that on first impression it lacks that immediately recognisable overly sharpened camcorderesque look that it's typically hard to get away from on the GH5/S.

Shot on vintage glass I think, and likely with filtration too.  Available on Vimeo too by the way.

I agree that weight is nice, but this camera does not have enough. I added a cage and monitor with a battery and it feels a bit better. I still think IS lenses are clutch. 

My C70 with the cage (no monitor) is only 10 ounces less than a stripped down C300 Mkii. Kind of interesting. The C70 is still a better gimbal camera and easier to pack around, but it's not exactly a light weight DSLR.

The big bummer is the lack of EVF. You lose that point of contact. It was on purpose so people would be forced to buy a C300iii for a true documentary camera.

Ah - now that you mention it, both the hire lenses I was using had IS engaged!  I'd forgotten that because I generally own manual, non-stabilised glass, so I had mis-remembered the setup.  Apologies!

Out of curiosity I weigh the camera, without battery 1.2kg, with A30 battery 1.4kg, with sigma 18-35 and adapter it is 2.35kg, with handle probably another 100g. R5 with 18-35 and adapter is 1.65kg.

So C70 body with battery is nearly 2x weight of R5 body.

 

The weight is a good thing in my view.  I had to do some off-the-cuff hand-held shots with no rig.  No micro-judder!  None!  I decided to build some more handheld into my project.  Built like a mirrorless, but really handles like a camcorder.

eta: I was using the A60 (or whatever the larger battery is called) though.

Yeah I m definitely wanting to try it for maximum DR

I just tried the C70 on RS2 with smallrig rs2 plate, it can just fit the c70 if you took grip stripe off and insert from the back of the gimbal, flying with it is no problem.

 

 

Yikes!  I'm going to be using that same combo on a shoot soon.  Do I need to get that baseplate or will the standard RS2 one work?

On 5/13/2021 at 11:31 PM, ntblowz said:

I m really impressed with C70 so far on this one limited shoot, the black is soo bloody clean! And the Stalman lut is really nice, more pop and nicer uniform skintone unlike Canon lut which can go over the place.

 

Next few weeks will have some big project, so eager to shoot with it!  My R5's only grace is IBIS and FF look..

 

Shadow integrity is phenomenal on the camera.  Would make using the (otherwise excellent) previous gen cameras like the C300 mkii, and the C200, a bit of a pain now.

Agree about the official Canon LUTs - they are a disaster.  Not quite sure how they've allowed that to happen.  I actually genuinely believe some of my early concerns, re: highlight rendition, etc. may have been down to how people have been applying the official LUT! 😲  

Would recommend trying out CLOG2 over CLOG3, as the latter is really designed to protect shadow in a way that isn't really necessary with DGO.
