GH3 Best Video Settings

    I even gave it try on philip bloom's Genesis, shot on GH3. LUT tested on dark scene where the skin tone looks too light and not contrasty enough in relation to the rest of the frame. It's really not a big difference but too my eyes, it's night and day.

    @flablo Yep I know. But to be honest with you I don't believe in any kind of "quick click color correction", patches or effects. Im my humble opinion those are a lazy man's or just flat out amateur's tools. Things like FilmConvert and the rest are just ways for me to spend more money, not learn and be lazy. Don't get me wrong, I think using these to get you close or "in the ball park" is great. But if I can't adjust color, saturation, tonality by understanding the theory of color and light.... I should choose another passion. Again... this is just my humble opinion. Not trying to offend anyone so please accept my apologies if I have.

    Racist camera the GH3 ... :)

  • yakyak

    @maddog15 From what I have seen, some skins are harder than others to correct like Asians skin, while darker skin seems to be the easiest.

    @yak Great thanks. 3:14 am where i am. I'm shutting down but I'll get back to as soon as possible tomorrow. Going to test it on an interview I shot last month. For some reason this guys skin was brutal to color correct.

    Thanks again for all you effort. I know this camera can do it. It's just a matter of figuring out the finer tweaks of the camera's personality. Check this link. Shot with the GH3 by Gary Orona and yes.... skin is possible!

    Here's his reply to my comments: " Thanks Frederick. Yes skin tone is always a challenge especially since a lot of my work involves a lot of skin! Adobe Speedgrade works pretty well and gives ridiculous amount of control. SpeedLooks is a company that has these amazing settings you can buy for Speedgrade that are fantastic."

    That .cube file is not so good the LUT doesn't preserve the highlights of the skin tones... here is a much better one. (Been working on it all day) Feedback from you would be much appreciated.

    Never mind. Figured it out.

  • maddog15maddog15

    @yak I'm on a mac and for some reason i can't download the .cube file. Only lets me "copy" the image. Haven't had this problem before. Any suggestions? Really want to try it out.

    Thanks much

    @yak

    Sorry. I though "RAW (ungraded)" video. Are you always using -5 color. That may leed chalky look. I use 0 color. I also prefer auto WB most of the time.

  • yakyak

    @vesku

    First photo is ungraded RAW picture straight from cam...so yes sharper, richer, everything else... 2 last one Natural -5 -5 -5 -5 WB tungsten

  • VeskuVesku

    @yak

    I see the problem if one wants to make some video product and the goal is normal looking rich color and contrasty result that looks good in every average monitor or tv.

    I watch my clips usually straight without editing and I have been very happy with every aspects of IQ and colors. Maybe GH3 videos benefits of high end colorful displays I have. Personal tastes matters too. I like flat look with good dyn range. If too flat I adjust gamma a bit in player.

    Do you use standard or natural profile. In my opinion standard profile causes problems with skin tone in artificial lightning. Too colorful, yellowish or reddish faces. Natural is more neutral in electric light like smooth also in GH2 in electric light.

    I think in last example that first photo is best but too red. How you do it? Profile, settings,WB... 2 last one has bad sharpness, why is that?

  • yakyak

    @Vesku Look at how much the skin tones are flat looking in a contrasty image in second pic, and how you can recover that in 3rd.

    First Picture: RAW from camera. Second Picture: .MOV graded to match RAW Third Picture: .MOV graded to match RAW + Hue adjustment

    anyone who has tried a warming filter which is good for skintones, to see any difference?

  • yakyak

    @vesku

    I agree the GH3 as better DR than 5D. As for skin tones, gh3 is very bad, you need a very aggressive grade to get normal looking skins. I like to grade flat, in fact I LOVE the flat look and when my GH3 image is flat the skin looks like chalk. And when you grade your image the red is may too bright. Try to shoot a RAW picture and compare it to your .mov, you'll notice that the reds are less bright.

    I love the RAW colors of the GH3, the jpeg and video colors not so much... until now.

  • VeskuVesku

    @yak

    OK. that explains something about contrast. Vimeo and Youtube seems to crush GH3 exellent dynamic range.

    Must we compare to 5D3. In my opinion it has too contrasty video and skin tone. I think that GH3 skin tone is more natural looking with its open and pleasant shadows. Is it so that people/customers want contrasty look?

  • yakyak

    @vesku I don't have a mark3 it was a test using a video on vimeo... explains the crushed everything, it was just a quick skin tone exemple...

    I'll agree it's not the best test, but still... if you look at the colors on the scarf the reds are at a good level vs mark3

  • VeskuVesku

    @yak

    It is strange that I get never so red faces like in your examples. This latest looks also very contrasty. Is it standard/contrast 0. The corrected version has better color but contrast between face/black parts like beard is too hard for my eye/monitor. How you do these frame samples? Are there all video levels in JPG photo?

    Here is the first picture with heavy gamma setting. There is crushed blacks. I dont see those in my videos even when I underexpose.

    @vesku

    I've trying shooting underexposed, still the red are too bright. The issue with GH3 for me was that I've seen hundreds of gh3 footage on vimeo and I've never seen a footage with good skin tone (without crushing the midtones) the skin tones contrast never matches the overall contrast... It's a knows issue that the skin tones comes out a bit chalky.

    Now Canon have always had better skin tones, when I apply my "LUT" to a GH3 still, it makes it very easy to match canon skin, did panasonic wanted to have a different video image than Canon?? Maybe...

    @superset thanks for the info

    Testing against raw. Look at the magenta channel behavior vs raw with and without red channel LUT

    A better .cube file soon. I'll try to make it final.

    @yak

    You are talking about red channel problem but is it more correct to talk about red colors problem. Your correction affects only for red colors, not for all red channel if I have understand correctly.

    I am still thinking that part of the solution might be a slight underexposing because that leads to less saturated and darker colors. Then I can use flatter (-5 natural) profilr. It works for me with my displays but I am not sure if my calibration is absolutely perfect. I can add saturation to my plasmatv and there is no skin tone issue for me. I dont still underestimate your issues.

  • SuperSetSuperSet

    Yak, thanks for putting that .cube file together. For Premiere CC users, you can load this file using the 'Lumetri' video effect. When you load the effect, just point it to the .cube file and it appears in the Effects Control. Much better than Magic Bullet LUT Buddy.

  • yakyak

    @surfculture at -2 the red channel problem is less apparent but the same amount hue adjustment is needed to correct to skin tones. If we find a good way and apply the exact amount of adjustment needed (hard to figure out right now) there will not be a problem shooting at -5 (in fact will be better for gradability)

    I'll continue experimenting with the hue adjustment to create a good LUT .cube file, my first file as too much red saturation. I think the way to do it is to compare the channel of the .mov against the red channel of a RAW picture. As I don't see that problem when shooting raw pictures.

    The second step, would be to have the same adjustment in camera, but no hack for now and I don't even know if that is going to be possible...

    @lumixmaxgh3 I have not experimented too much with moving the wb ajustment, for the little I did it does not seem to reduce the "brightness" of the red channel, as the red seems to be too bright in the mid tones.

  • lumixmaxgh3lumixmaxgh3

    @yak So, for you the manual wb is reliable for the correct color of skin? Is not it better moved a few point toward the magenta?

  • surfculturesurfculture

    I go to try that, I follow this topic since any time, todays my GH3 is standard -2,-2,-1,-5 after tried standard -5,-5,-5,-5, what are better ? and after I used resolve to the red... You make a good job, in waitting an hack.
