@edgenumbers Nice work, matching both the shadows and the saturation of the red flowers. Interesting to see how close GH2 Smooth is to GH4 Cine-V at 0 Pedestal. I'd have expected a negative pedestal would be necessary to match the GH4's shadows to the GH2.

First Test 4K Cinema 24p

settings :

CINE D: Everything at -5, except Hue at +2

SHADOWS/HIGHLIGHTS: Left at +0/-0 or sometimes +0/-2

SHUTTER Angle: Set to 180

@Superset

I tested the settings that @edgenumbers provided. I still had to color correct a little bit to try and match the colors and even so it is still slightly off. Here is a quick test that I did I did not spend a lot of time on this just a very quick color correct edit to see how the footage matches up.

What is weird is that for some reason the GH2 seems to be a lot brighter at the same Fstop on the lens that I was using. In terms of skin tones I like the Portrait setting or the Natural setting they are actually really close. The footage looks great right out of the box with very little color correcting in post. Basically adjust black and white levels and bam you are done.

Side note: Notice the difference in moire between the GH2 & GH4... IMO I would rather shoot 1080p with the GH2 rather then the GH4 due to the crop factor and also aliasing and moire.

@AdamT

I agree. I did not buy the GH4 for 1080p it was for the 4K. The opposite happens though if I shoot in 4K and export to 1080p. So for the GH4 I see no reason to shoot in 1080p except for 60p other then that everything will be shot in 4K not to mention the fact that you have tremendous flexibility in a 1080p timeline.

@edgenumbers & @Azo

I did a similar test too , and I found @Azo setting a little bit better , Natural for GH4 vs Smooth GH2 , with some differences in settings .
as @Azo said GH2 seems to be a lot brighter ( In fact,to get same exposure I set to 160 ISO GH2 vs 200Iso on GH4 , and I had too , to color correct a little bit in post to try and match the colors ( GH2 WB +1 Magenta +1 blue to tone down green colors cast) all shots taken on a tripod same lens ,focal , aperture and shutter , at the same distance from the subject, even to see three different crop factors.

For Me at 1080p GH4 looks better in DR and colors rendition, However, with more moiré .

Just a simply experiment not scientific test.

...sorry my English : )

Thanks for the excellent info on matching GH2. Anyone try to match GH3 yet? I'm trying to decide if the 2 or the 3 is a better B-cam to the GH4. Ideally I'd like to match GH4's Cine-D to a profile on GH3 to keep the maximum DR.

@Azo ! Thx bro ! I'm living in "the old country" LOL in Italy near to volcano Vesuvius in Naples ! and yes there are a lot of interesting place ,

@chauncy

LOL, I was actually performing some tests to see how sharp some of my lenses are in the corners. I know it looks getto but it works ;-) I picked up a Canon V6X17 17-102 F/2 just to see if it would cover the sensor on the GH4 so I just left this up and figured what the heck...

@All @valpopando

My latest findings in regards to matching the GH4 to the GH2. IMO using the natural picture profile on the GH4 and the vibrant picture profile on the GH2 yields the best results for matching the colors etc. The colors are not an exact match but it gets you pretty close.

GH4= Natural Picture Profile = 0 0 -5 0 0 GH2= Vibrant Picture Profiel = -2 0 0 -2

The methodology for conducting these tests was to test everything at the base settings in terms of the picture profiles then adjust from there.

@kikojiu

Wow something must be seriously wrong with your camera, can you post a link with the video via dropbox. I am extremely happy shooting with the GH4 in 4K. The noise pattern is really fine and way cleaner then the GH2 IMO.

@Azo thx for your further test , I will try Vibrant on GH2. and yes in the indoor shoot I performed with a 18% grey card ! but the result of the color of GH2 is always a little different! @kikojuu @Azo About ISO noise , I too have had very different results, sometimes the noise is very loud , otherwise almost imperceptible, I always suggest to overexpose instead of open shadows in camera setting

Shot Monday and Tuesday with a white backdrop. GH4 on A-Cam with the 12-35, Cine-D 0,0,0,0 and curve was +1, -1. GH2 on B-Cam with the 35-100 set to Standard 0,0,0,0.

I white balanced both with the white board on the back of the DSC One Shot Chart. Then I shot the chart from both cameras.

Next up, I imported the two chart shots into Davinci Resolve 11 beta. I used the chart auto-balance feature and set it to the DSC One Shot chart. This got the two images very close.

I exported the 3D LUTS from each shot and imported those into LUTutility. From there, on to FCP X where I applied the LUTs to each respective camera. I tweaked it a little bit with the color board and, boom, perfection.

This was a seriously quick and easy way to balance the cameras. I think I'd probably shoot at all 0's next time if I knew that I'd be able to shoot a chart with both cams.

Uploading some stills from the shoot. Blanking out his face since he's SAG and I don't want to piss off the client. Point is, this was crazy easy to do. If you can afford a chart, I highly recommend getting one and using it when matching any cameras.
