@apefos I have same recordings of more patches that I have not compared yet. Including denoise24, The patch setg, patch2000h, setj8000h. patch dcn6, sedna Aq1, Canis night, intravenus 2....

@apefos I tried a long list of patches before. Now, a screenshot is not a video, and a video, shot in some specific situation, is not exactly what you find when you're working in real world.

While shooting in real world (indoor, outdoor, sun, rain, morning, evening) your last patches are unmatched (considering artifacts, banding, moiré, lines, noise, flickering, whatelse... And texture); talking about chroma, well, maybe some improvement is possible. I'm just supposing it is possible.

@frullaccia this is what I was pursuing since the begining, good to know.

About chroma, I did a test now. I increased the quantization in a similar design inpired on Denoise and Moon, but not so big increase, to perceive small differences. The chroma noise becomes small, not so much, but I can see the difference, but the problem is: textures got mud, it flattens the surfaces. It seems there is no free lunch in color, it seems to be a choice between good texture with some noise or flat surfaces less noise. I am trying to find a sweet spot now, in quantization and design, I will priorize texture, less possible noise with good texture.

Here is first video at 640 iso

@apefos You are right I forgot to turn on a second light source for moon t8. I can redo it easily. Although I might redo everything for a few reasons, including the mistake of using the kit lens 14-42 which required new focus for each patch loaded. So it is possible for human error to be involved. The other lens I have is canon fd 50mm.

Also I forgot about iso bug 160-320-640-1250. Although only 320 appears affected in my camera.

I have some thinking to do about my testing setup and if I can find a better quality and faster method so that I can include many more patches.

I am unfamiliar with premiere pro, so I don't know everything it's capable of rending out. But I will find something good.

I think I will redo at 300% or 400% crop. This was only 200%.

@Manicd you said you have interest in developing patches, please read this topic, if you think you can survive the things in the topic you can do patches:

@Manicd try water falling from a tap, see

I am doing progress in fallback chroma matrix, iso 2000 is looking like 800

I did it, best noise reduction in luma and chroma.

The stable version is pretty good, I think there is no need to use the high datarate version, but it is here also.

Matrices improved with ideas from denoise patches and moon, also flowmotion, not a copy from them, a new custom design. I also tested a little more quantization than this, but it started to hurt textures, so it is in the sweet spot. I did try in all positions of the matrix, first digits, last digits, respecting the dct frequency in luma all matrix and in chroma first digits, last digits of chroma are high quantization to improve the noise reduction and do not hurt.

It is good to have neatvideo inside the camera!!! (not so powerful as the software is, but very good.)

To my eyes iso 2000 is the new 800.

works for all isos 6400 and below in same patch.

Maximum safe iso is now 6400, iso 8000 starts to show flickering from the sensor impossible to remove.

please users, say your opinion after tests.

@apefos You have been doing these patches since last year with many changes and information about superb image quality etc. I would like to know how you evaluate the image quality and if you have any comparative tests to show the differences between versions.

@Manicd Of course. And I appreciate!

@haribabis nice test, you are the cave man! It seems all of us are... just some sense of humor. did you use the last setg with denoise improvements?

Last setg with denoise improvements, my tests with neatvideo conclusions:

avoid iso 2500 it shows flickering in hbr and 24p.

720p does not show flickering, good up to iso 6400.

the image up to iso 2000 is pretty good in all recording modes, including face in low light.

neatvideo performance shows less trembling using temporal denoise "1" and luma spatial denoise 30, chroma spatial 100, and chroma +50 in first sliders, selecting the area in a fine grain instead of a gross dark area works better:

neatvideo works ok in iso 3200, can be useful for low light.

iso 2000 and below is just great after denoise.

isos 4000, 5000 and 6400 denoise ok if you need to get the shoot, also works, some film grain in post can save them, excellent results considering it is the old GH2.

avoid iso 2500 in 24p and hbr, shows flickering.
