GH4 Cinelike D Comparison

Many of us have wanted to see what the Cinelike D footage looks like from the GH4. Andrew Reid has a preproduction unit and has been doing some testing. He has posted a article and video that compares various picture styles and cameras. Here is a link to the article: http://www.eoshd.com/content/12445/panasonic-gh4-4k-production-diary-day-3-shootout

For a quick comparison, I downloaded the original video footage and saved some stills. It looks like the Cinelike D really does flatten the image more than we're used to on previous GH cameras!

2)4K Cinelike D
3)4K Cinelike D set to flat, -5

Again, this work was done completely by Andrew Reid. Please visit his site for more information. I am merely an eager filmmaker with a preorder for this amazing camera.
 
Yeah, the HVX200 also had those profiles…..Cine D really made the video grain up, so yes it was flat but then you had to crush the blacks to back off the grain.

I have been downloading and looking at Reid's footage. SO far the GH4 looks much better (it should - 4k vs. 720p) and perhaps this go round Cine D
can actually prove to be a valuable tool in certain shooting situations.
 
I already pre-ordered but the Driftwood piece made me feel extremely good about doing so. I think it will fit in quite nicely with what I want to do.

GH4 CineD vs CineV

Thanks for the link to this comparison footage. The GH4's CineD and CineV tone curves look very similar to the CineD and CineV curves on the AF100. On that camera, I found CineD produced the closest match to the GH2's look in its Smooth profile. To get a good match in contrast, however, I had to set the AF100 to its lowest Pedestal setting, which blackens most of the shadow details. With the GH4's pedestal control, this will not be necessary, and it should produce a major improvement in video shadow detail over the GH2.
 
This image is definitely flat, but is there any additional dynamic range? While the 4K is amazing, especially at this price, I'm still not convinced from what I'm seeing that even with Cind-D dialed flat that there's any more dynamic in with the GH4 than in the Gh3. There certainly will be more data in the shadows and a much more gradeable image, but range looks identical. Perhaps the production cameras will be different? Or is there more range attainable by adjusting the master pedestal?
 
The idea of Cinelike-D is that it distributes the exposure range in a manner designed to increase dynamic range. But at the expense of looking flat and desaturated before adding a contrast curve in post. The suggested procedure is to underexpose compared to where you expose using a profile with the contrast already built-in. Cinelike D, theoretically, increases dynamic range by nearly 1 stop. It's also supposed to be noisy in the shadows.

My hunch is it will work best in high contrast situations like bright sun, when you need the extra range but can offset the noise by shooting at 200 ISO. In more controlled environments, like studio lighting, other profiles might work better.
I can't wait to do tests.

panasonic claim half a stop increase in dynamic range. I don't see how anyone can tell what the dynamic range is from the limited amount of 4k footage in the wild, let alone from compressed YouTube uploads.
 
Im guessing it would be absolutely beneficial at 10bit 4:2:2 recording.

now after seeing the 1080 to 4k,
damn i want a 4k recorder 10bit 422
 
A half-stop difference would indeed be impossible to see just from looking at random clips, so I would buy that. I had read claims of 12 or 13 stops of DR with this camera, and if that were the case I think an experienced eye could see it, even in random clips on YouTube.

If a half a stop is true, it's a but disappointing to me. Still seems to be a great camera though. But I would trade 4K for 13 stops of DR, the GH3 is already sharp enough for my purposes.
