GH4 Leeming LUT One – the best LUT for the Panasonic GH4

Paul, many thanks for the fast delivery of the Leeming Lut. One question: compared to the "Panasonic V-log to V709 Lut" your "Lut One V-Log v401" looks quite dark. Whats the reason for this?

The Panasonic one is too bright, but at any rate, I'll be releasing a v402 LUT soon that makes things a bit brighter. For now, you can raise the mids a touch to match the Panasonic LUT's brightness.

HTH!

Cheers,

Paul :)
 
Paul, will the CineD LUT be in the next version? Of course prefer vlog, but with the high ISO vlog bug will need to rely on CineD for a while in a number of scenarios.

Thanks for all your hardwork and insight! Also looking forward to your NR tests and how the GH5 processing may differ from the GH4 in terms of creating clean high ISO imagery :)
 
Cant wait to see real competition Vlog vs CineD or standard in DR advantages.

BTW I thought G80 has the same GH5 sensor but it is in GH4 and G7 group. Is it really same its known as a better one?

Thanks for your work!

Even if it's the same sensor, the processing power is in another league, and that's where the picture quality improvements come from.

Yes, I'll be releasing the Cine-D alongside the v402 update :)

V-Log has a two stop advantage for sure, if not more, with the GH5 in 10bit 4:2:2 space.

The G80/85 have the same sensor as the GH4/G7 but better back end processing from what I can gather.

Cheers,

Paul :)
 
I am hearing rumors that the GH5 has less dynamic range then the GH4 when shooting in 8bit. Any truth to this?
 
By the way, I've released v405 of both Cine-D and V-Log LUTs for the GH5, with the major changes being a brighter curve which most people wanted, and fixing the solarisation issue I saw in one or two skin tone clips. White balance was tweaked as well to make it more accurate.

Here's a review which Karin Gottschalk just published on both Cine-D and V-Log LUTs :)

Here's a PDF guide on how it's used within the various NLEs.

If you use DaVinci Resolve or Premiere Pro, there is LUT support built directly into the programs. For FCPX you need to install a LUT plug-in (there are various ones out there).

HTH!

Any update on the debate from 1-2 months back regarding optimal NR settings on GH5?

Traditionally believed to be -5 NR, but with GH5, the argument went that better results were seen with NR left on as it was a huge part of the design and circuity to giving clean high ISO performance?

Anyone test this? Would love to know how the image is -5 NR vs NR @ 0, both in normal ranges 400/800 and high ISO ie 1600/3200

Still trying to dial in my optimal GH5 settings...
 
I'm still advocating NR -5 because it's much better to do a controlled noise reduction in post if needed, rather than having the camera do a quick and dirty noise reduction pass with no control.

Cheers,

Paul :)
 
I would caution against lowering the default noise reduction option.

First of all noise can be reduced most effectively with signals coming from the sensor, second noise has a strong negative impact on compression efficiency.
By lowering the noise reduction you will wind up having more compression artifacts. All you can do in post is to smear that out with the consequences of having a less effective resolution.

I would leave the noise reduction at default.

But the GH5 does temporal NR, so you may get better results if it's set to more than -5.

This is something I am going to test at 3200 ISO, to try and figure out what's the best combo between camera NR and using NR in post. ( I'm using the current version of NeatVideo for my tests )

In theory yes you are absolutely right. Starting with any image processing with a raw signal will always be the best. In practice however that isn't always true when it comes to noise reduction. Cameras have very limited processing power and they need to de-bayer, scale and process the image 60 times per second. In the case of the GH5 that is 60 times per second at an over 4k resolution. That is a massive amount of processing power that even a top quad core computer can struggle with. The NR done in camera is nowhere near as sophisticated as that in a program like Neatvideo. Neatvideo is painfully slow for a good reason and that is how much time it can take to deal with noise reduction. NR is one of the most intensive tasks you can do in image processing. Neatvideo is also designed to compensate for some of that image compression on high noise material.

The engineers at Panasonic are some amazing people but they can only use the processing power available to them and speed and stability are an absolute must.

Just like anything else we do the answer is really it depends. It can depend on a lot of factors and having used Neatvideo a lot myself over the past few years I can tell you it does a really good job on -5 NR material. Of course if you shoot ISO12,800 and have a ton of noise use are kind of screwed either way. The in camera NR is going to create such odd blotchy artifacts I would honestly take my chances with Neatvideo making sense of the H264 macro blocking.

In the case of realistic ISO levels 200-1600 the macro blocking damage at -5NR will not be enough to harm what Neatvideo can do. If one is shooting at insane ISO levels then maybe, maybe in camera might do better but I think it is important for each person to test it out. Any NR is a massive alteration and damage to the original video. Which one is better is not the right question here and it has more to do with which one looks less weird to each person.
