GH5 GH5 - Best non-log setting?

[Thomas Smet]

I've found that Cine-V with NR & Sharpness at -5 and -1 Saturation gives me a nice image with really full skintones. DR isn't the best, but I don't think it's the strong point of this camera in general.

I've used V-log with varying results. The patches of green/magenta are disappointing and were even present when outputting 10 bit to Atomos.

Are you talking about the GH4 or GH5? The GH5 is an entirely new camera and so far does not seem to have the same color issues as V-log on the GH4. With that said I have used V-log on the GH4 a lot with the Atomos Blade and rarely had any color block issues. It could happen in very rare cases but it was very rare.

Yes GH5. I've never shot with the GH4. There's definitely some weird green/magenta things going on with v-log footage. Film a white wall with v-log and you'll probably see it. Unless my camera is broken, but I doubt it.

How did you expose your footage and how did you handle it in post ?

I have seen some great GH5 10-bit V-LOG L footage that did not appear to have the same green/magenta issue that I've seen with GH4 footage, so I am very surprised that you are seeing it ???

I've seen it in internal 10 bit, internal 8 bit, 10 bit out to Atomos to prores HQ. It can be well hidden if the scene contains a lot of texture, but it's apparent on clean surfaces like walls and skin. I can see it in Premiere/Resolve and also just viewing the clip in a player like VLC.

I don't think overexposing will fix it as typically certain parts of a scene will be lit differently anyway (i.e. if you light a subject and have the light fall off behind them, the background is meant to be underexposed).

I'm certain other people will have noticed this, but the fanboyism around the camera is pretty extreme so I guess nobody wants to complain about it.

Anyway, this has led me to believe that using one of the normal picture profiles is the way forward with this camera. Maybe it'll be improved with the new firmware release...

Well that just destroyed any credibility.

Also be aware that VLC, although it does playback 10-bit footage, doesn't do a very admirable job of accurate rendering. Also not that keen on how Premiere treats GH5 footage.

To me it sounds like incorrectly exposed footage compounded by problematic post work.

I'll have do some tests once the new firmware is out, as I want to see how different the 400 Mbps recording is.

I've seen people murder their footage in post by not using the correct LUT, or not handling color properly, so sometimes one small mistake in post leads to this kind of thing.

I wasn't thinking of over-exposing to fix anything, but rather getting the correct exposure when you shoot. GH5 V-LOG L has 12 stops of DR if you get your exposure bang on, but things can go south fast if you f*ckup getting your exposure right. ( I have a Minolta Spotmeter F that I've been meaning to calibrate for video, so I will add this to the mix to record what the true exposure range of my subject is )

I'm certain other people will have noticed this, but the fanboyism around the camera is pretty extreme so I guess nobody wants to complain about it.

I haven't really seen much written about this for 10-bit GH5 V-Log L footage, but tons for 8-bit GH4 footage. It reminds me of the time I first tried using the Logarist ( logarist.com ) system with GH4 footage, and how I finally was seeing proper greens ( not those hideous yellow-greens ) that almost every other color system was producing. Right away it was obvious that the Logarist system was able to get bang-on color with virtually no work, where everything else was a struggle. I will try your white wall test and see if I can induce the magenta/green "grain" in the image, but it won't be for a couple of weeks.

When I first started putting 10 bit V-Log footage into Premiere I noticed that in bland / white walls I was getting magenta macro blocks still and my heart sank. But checking the same footage in FCPX it was absolutely fine. So I realised that in Premiere you must have a 10 bit codec as your preview codec (I used Pro Res 10 bit) not the default mpeg codec, and you must also have maximum bit depth and maximum render quality turned on in the sequence settings. That has got rid of any macroblocks in 10 bit footage using premiere and I'm been shooting loads and loads of interiors etc.

Your camera maybe broken....yours is the only report of this I've seen and no indication of this in any of my footage....as for fanboys....plenty of people owned the GH4 and reported the internal VlogL problems....
