GH3 Best Video Settings

  • @rNeil - the importance of calibrated monitors cannot be overstated (not to say they don't have calibrated monitors). The difference between even monitors from the same manufacturer amazes me. Even after calibration, there are notable differences. An example would be the two monitors I have. The Acer 243W(?) is a very old monitor (5+ years) that has a CFL backlight and only is potentially capable of sRGB calibration (98% gamut). My Dell 2413 Ultrasharp uses LED backlighting and is Adobe RGB capable (set to sRGB gamut in monitor), though I only have it calibrated to sRGB (102% gamut) because sRGB is the standard (foundation) for almost all viewing we use (web, NTSC, rec 709, etc.). Both were calibrated the same day using the same software and i1DisplayPro.

    Even though these two monitors are calibrated to the same standard, with the same white point and brightness, the overall contrast of the Dell is noticably better than the Acer. The colors are very similar, though there are noticable (if very slight) differences between the two, especially in the blues.

    Oh, my point. Even slight differences between "calibrated" monitors can make a pic/vid look different. If they aren't calibrated (with good, proven software and sensor), the variation can be pretty large. Most people don't notice it unless they have a dual (or more) monitor setup. I use my Dell for color correction/grading if only because I figure (i.e. hope/pray) it is actually closer to the standard than the old Acer since it is actually made for that purpose.

    Anyway, I, personally, have not noticed an objectional color cast or texture to skin tones with my GH3 and monitors(both). Perhaps there is some variation in the sensors that cause some cameras to perform worse than others? An interesting experiment to try.

  • @jonpais AND @yak ...

    So I've been in professional imaging for nearly 40 years. In me younger days, it was (within the pro portrait crowd) Hasselblad or Mamiya RB67. The acrimony at times was so absurd as to be humorous in a sort of snarky way ... a pox on both-houses look at things, perhaps? (Hassy lenses were sharper with a titch more contrast but for large enlargements the much larger negs of the RB's made for sharper prints ... BARELY ... mostly seen with a loupe. Why castigate each other over those small differences?)

    In digital for portrait photogs it's been a 3-way mashup ... Canon, Nikon, or the "snobby" hold-outs in film. but note ... it doesn't make any difference now between Hassy & RB users still shooting film ... they're together against the World.

    You two have different eyeballs and from a couple of the comments your monitors are probably not identical either. You have slightly different approaches but not as far apart as it seems to both of you, compared to what else I see and hear about. Laugh at your wonderful human uniquenesses, sip your favorite beverages, and enjoy perhaps teasing each other a bit. It's those differences that make live worth chasing after ...

  • @yak and if your position is that no matter how well the subject is lighted, no matter what settings one uses, no matter how brilliant a colorist one is, one simply cannot get a pleasing result from the camera, then I'm afraid the two of us have nothing more to say to one another.

  • @yak abysmal? I'm curious: exactly what is meant by 'me holding the cam or you..'? that you don't like the skin tones in the shots I shared? Actually, even in the four latest screen grabs I just posted (page 30 of this thread), if you look carefully, you'll see two Western faces, and they have quite a pleasing rendition to my eyes, and that's without any color correction applied. Abysmal means appalling, which I think is quite a strong word: if the skin tones were green; if people looked like martians; or if I were shooting in daylight and subjects appeared like they were shot under fluorescent light, I might agree. But that's simply not the case.

  • @jonpais To my liking GH3 skin reproduction is abysmal, graded or not, well lit or not. Me holding the cam or you... If you like the results it's a good thing, I wish I did...

  • Had a good laugh at the way @jonpais considers I'm spreading conspiracy theories. Naw, just from human experience ... and having been through the pro-side of Nikon still cameras ... and so many other products where engineers determine what the problem is and the best solution ... and don't really want to talk about their internal decisions ... and the "user base" doesn't necessarily agree with the engineers.

    Such as ... the Nikon D3's twin "user banks", each with four options you could make. One bank for certain kinds of settings, the other for a different set. Sounded amazing. A bit confusing, but amazing.

    Why the two banks? One sort of "settings" and one sort of "shooting" ... but an interesting set of choices for what's included in each. Kinda hard to figure out why but ok, just use it, right?

    One leetle problem with the utilization ... you couldn't lock either bank or any of each banks four presets you could create. You could set them, name them ... but not lock that down. SO ... invoke a bank/preset, start shooting. Change ANY setting on your camera, and you've just reset that bank/preset. Permanently.

    The lack of a lock made them worthless to use. I tried & gave up. The only pros I know that actually used them for a while kept a flash-card with their banks on it in their case. Every flippin' time they pulled the cam out, they'd re-load their banks from the cards. Stupidly implemented great idea.

    Now ... would the Nikon engineers listen to their users? Nope ... in fact, just mentioning that in a meeting with the engineers would get them angered, yelling at the pro they'd brought in to advise them that he clearly was incapable of understanding the true brilliance of their work, and they'd leave. To the point of cancelling the relationship with the pro they'd brought in to advise them on how the users would like that camera set-up.

    In any industry there are many accounts of the wisdom of the engineers vs. the wishes of the users. So ... just putting my knowledge of human nature and engineers vs. users relational issues, the intriguing case of the pink plasticene skin of the GH3 (which is not common to many other cameras Panny or otherwise) and also a quote I saw a year back or so from Panny about their approach to adjusting the in-cam processing to handle that all-important detail of facial recognition and handling of human skin ... a general blah-de-blah comment but an extensive one of blah-de-blah ... well, it seems a reasonable assumption to me that there were some design choices in this specific camera that led to what we've then had to clean up.

    Calling that a "conspiracy theory" ... now that's a howl. Is it any kind of claim I'm making about knowing things or being prescient or able to mind read through several thousand miles of separation and language barriers? Of course not. Nor is it any more conspiracy than discussing why they left say zebra or focus-peaking off the GH3 while clearly prepping them for inclusion in other cameras released about the same time. Panny's never given a detailed response from their engineers on that one, either ... but again, it was a design consideration & decision.

  • @maddog15 no hard feelings. & I'll accept somewhere between 'quick' and 'arduous' ;

  • @jonpais #1 Not me. I do everything I can to shoot a well exposed ISO 200 shot with the GH3. That said I get great results up to 800 ISO - but that's the limit unless I'm doing something that supposed to have a raw look to it. Problem for me is that high ISO on the GH3 doesn't produce a nice cinematic grain. Just looks more like the onset of blotchy noise or small artifacting. So unfortunately pushing the GH3's ISO higher doesn't yield the same nostalgic, moody grain results that other camera systems might. (BTW: I'm in the process of editing a job where the footage was originally shot on 35mm film then transcoded to ProRes HQ files. It's "noisy" yes. But with a beautifully rich cinematic grain. Nice.) #2 I've actually edited "raw" AVCHD files and achieved wonderful results in Premiere Pro. NOTE to PP users: I found the trick is importing the "private" file directly into PP's bin using the "import files" menu. Dragging the footage from the desktop into the bin (which i did frequently since I'm on a Mac) apparently looses some of the multitudes of information buried within the folders and files of the Private folder. That said, working with all the associated files within files of the Private folder is a pain in the a**. So now I just use ClipWrap and rewrap AVCHD files as single ProRes HQ files. Very tidy. #3 Good looking faces. Very nice. #4 I object to your using the word "Quick" in point 4 above. Replace that word with "Arduous".... and I would completely agree with you! #5 The way you've redefined your objection on this one made be laugh. Good one. Worded like a passionate pro...with a sense of humor. That's what it's all about. IMHO :)

  • Okay guys, I don't want to battle it out with you, but: #1. Is anyone here saying it's worth shooting at iso800 for a tiny bit of added DR (provided there is enough light to shoot at a lower iso) when noise noticeably increases? #2 As for AVCHD vs MOV, I said the difference was all in grading. In fact, I would never edit AVCHD files directly. Also, the implementation of the codec varies from camera to camera, manufacturer to manufacturer. I see the transcoded GM1 AVCHD files as no better or worse than the GH3's MOV container #3 if you checked out the post office clip I shared here a little while back, you'd see many Western faces. #4 I won't deny the GH3 magenta issue, just saying in my experience, a quick pass in post is usually all it takes to correct. #5 I object to rNeil's unverified conspiracy theories

    @flablo in case you haven't noticed, most of the manufacturers are Asian!

  • @rNeil @maadog15 maybe it's stupid or it's been already discussed, but did we take in account that Panasonic is an asian company and most of the MFT market is asian? The majority of people I read from who said there was no skin tone issue were showing videos with asian people ... and of course asian skin tone is generally different from caucasian skin tone ...

  • @jonpais The great thing about this forum is it's about personal opinions based off of personal research. Some eyes are more advanced than others. After quite a few months of exhausting personal test's and broadcast jobs - it is my opinion that rNeil isn't spreading falsehoods. This is his opinion. This real issue is the way the GH3 translates color and texture of "white" skin. In my humble but very educated opinion, It's bad...period. It's been the biggest complaint about the GH3 on this thread alone. That can't be circumstantial. Can you get good skin? Yes. But, I've edited footage from 6 different cameras (from the GH2 to the RED Epic) in the last 8 months and the GH3 footage is always the "problem child" in post. It's especially notable or proven when I've done multi cam shoots with the same lighting on set for both cameras. That said the GH3 footage still needs work than other footage in post.

    @flablo Ditto your comments.

  • @jonpais frankly I believe that the only one spreading false information here is you. MOV and AVHCD are quite different, not just in terms of bitrate and file handling (everyone knows how it works here, no need to explain). Also All-I MOV is a lot different than not-All-I, in the GH3. Please take the time to read previous posts before picking on people who, as far as I have the chance to see here, showed plenty of skill and dedication

  • I hate to break the news, but the best iso to shoot at is the one that produces the least noise, which is iso 200. you just might get 1/2 stop better DR with some settings, but if the image suffers (less color saturation, creeping dots moving around the frame, etc.), it's best to shoot at 200. I haven't found any reason why AVCHD should be inherently better than MOV files, except that in the past, MOV files could be imported directly into the NLE, whereas AVCHD USED TO HAVE to be transcoded. Also, the file structure - when I shot with a TM900, for example, I got all kinds of extra files I had to discard. But that isn't true for the GM1, which CAN be imported directly into FCP now and produces beautiful looking images. The only reason to choose one over the other might be bit rate - often the MOV files offer a higher bit rate, which in and of itself DOES NOT produce a more beautiful looking image, but may be easier to grade than your low bit rate AVCHD files.

  • @rNeil Stop spreading your falsehoods. GH3 can deliver beautiful skin tones. It just requires careful lighting and grading. Here are screen grabs of ungraded footage shot over the weekend. If you can't get a natural look from these files, I assure you, it's not the fault of the camera. Please, no more unverified lies about engineers making pink detail-less skin conspiracy. It's utter, complete nonsense! https://copy.com/EjcvwpX6xfCM

  • Hi All, I've been following this thread, here's a couple of rough clips from a promo I'm putting together for some friends. -5 sharp and -5 NR rest at 0 natural ISO 400 underexposed the skin slightly using at the internal GH3 meter. I just do this for a hobby, I thought I was getting closer with skin detail and tone I was just interested if others thought the same, I've been guilty of making it look very plastic in the past I've realised so was trying something different :)

  • @maadog15

    Hear your pain. My clients aren't typically that critical of color in the work I do. So I've gotten by though I'd a LOT rather had the skin & color I wanted without messing. Still, as nearly everything I actually "worry" about is a studio-style interview footage, I can pretty quickly apply the standard fixes and not have to worry about messing some other part of the image up.

    I've got a couple personal projects I want to get to as possible, and they would be a LOT more affected by color-mangling to correct the wonderful gift of the Panny engineers. Worse comes to worst, I might have a GH4 by then ... ;-)

  • @rNeil Thanks for the feedback. And yes, if it weren't for Premiere Pro's wonderful secondary color correction and isolation abilities... I'd probably be the proud owner of a BMPCC. Just knowing, "I can fix it in post", is what's kept me from loosing my mind and patience with this fatal flaw in the GH3's "engineering." Glad to hear your take on the GH4's hopeful capabilities and upgrades. I'm saving for it as we speak - but the money is not exactly earmarked for the GH4 just yet.

  • @maddog15 ...

    First, most of the better footage of the GH4 that I've seen shows marvelously detailed NORMAL skin. Considering it's got both a new sensor and a completely different processing "engine" one would expect something different, and "normal" is the best you can hope for. Thankfully!

    That bit of nastiness the Panny engineers did to the GH3 to try and guesstimate what we the users would want in skin tones ... and build that into the processing algorithms ... was an abortion that keeps on giving. Clearly, the cam is designed to recognize "skin" color, then modify it ... to supposedly "our" ideal. Instead, yea, we've had to learn to get around it. It IS doable.

    Yak's LUT's are one good starting point. Another is slightly tipping the curve of the mid/upper-mids steeper to raise contrast in the areas of Zones V and VI coupled with a slight drop in red luminance/sat and very tiny up-tick at times in green &/or blue. The contrast gets skin detail back (the cam's clearly designed to moosh over skin details for us ... ) and the color changes give a more balanced color range in skin.

    In Speedgrade or most other grading apps (and some NLE's) you can pull a secondary to narrow in on the skin and do that pretty much only to "skin" areas. Or you can apply it "globally" in a primary layer or node and when done in small amounts does ok on the rest of the footage.

  • aha, ok, maybe it is because zuiko lenses are compatible to autofocus and stuff like this, with my c-mount that the only way is to be full manual is like I said, somewhere here in PV I read it and test it also. It needs, manual lenses

  • I'm using the Olympus 17mm and it only works in high contrast scenes.

  • @joethepro the iDynamic brings the same amount of noise as if you boost mids in post, anyway, if you want to use it and keep it on, you have to use any lens except panasonic lenses. With panasonic lenses it does exactly what you say, it's on only in high contrast scenes.

  • I just realized that iDynamic actually works pretty well, but unfortunately its usefulness is very limited. It only kicks in when it sees a large light source in the frame, and as soon as you move away from the light source the shadow boost effect turns off. This may be good for home video where its just set to Auto, but for controlled work its unusable.

    Does anyone know if there is a way to force it on, and to keep it on at all times? It would be amazingly useful if so. For now, its just limited to static, or low movement shots, with a big swatch of bright sky. Perhaps Vitaly could look into this when he gets to the GH3 hack? ;)

    Is it really any better, though, than just boosting the shadows and mids in post? Does the fact that its boosted them internally before the compression stage make any difference to quality?

  • ok, mov has more noise cause the image is a bit sharper, I just saw it, it is clear in my "raw" iso test but you can see it also in youtube in the two thin parallel curved lines in the edge of the body of bass, in mov the space between them is clear and in avchd you have to imagine there is space between them, it is big difference in my "uncompressed" video. I still prefer the color in avchd but mov is sharp

  • @wgtwo what do you mean by high iso, it is clear even in youtube's sample in the final 200% comparison that till 1600 avchd has less noise, anyway, higher than 1600 is useless. 50mbps must have more detail but I can't see where it is, just like the 60fps vs 30.
