Any fix for random color noise?

[brassplyer]

Things like this where there's problems that change from frame to frame. Sequence of 4 consecutive frames.

MergeChroma(McTemporalDenoise(settings="very high"))

Or some other strong temporal noise filter.

MergeChroma(McTemporalDenoise(settings="very high"))

Trying this script:

avisource("F:\sourcefile.avi")
ConvertToYV12(interlaced=false)
AssumeFPS(59.94)
MergeChroma(McTemporalDenoise(settings="very high"))

Getting this error:

[jagabo]

For the cache error: SetMtMode(). There's something borked in the mt build that requires an explicit SetMtMode() call when using many filters.

But I downloaded the four images and MCTD doesn't work well. Most of the noise is in the U channel, a little in the Y channel. Avideo sample would be better.

Here's about 3 secs. I appreciate it.

Okay, added SetMtMode(3,4) to it and it loads. The script as posted doesn't make much difference. Knocks down the bright purple peaks a bit but the noise "flames" are still quite evident.

Most of the noise is in the U channel, a little in the Y channel.

How are you determining that?

[jagabo]

ConvertToYUY2().VideoScope("side", true, "YUV")

[jagabo]

I didn't find anything that dealt effectively with that.

Can't remove those stripes completely, but made it less annoying.

Looks good. Script?

No script is needed because I didn't use Avisynth. Instead, I use AviUtl, with the NL-Mean and Wavelet denoising plugins.
(I have not release the English version of the wavelet denoise plugin yet... after the holiday maybe.)

To install this do I just put the whole extracted folder into the Programs directory or is there more to it?

Just unzip the package to anywhere you have read/write permission.(e.g. In "My Documents" or "Desktop")
Then, get the NL-Mean denoiser plugin from my site at:
http://mavericktse.is-a-geek.com/wordpress/archives/1385
and extract the .auf file into the .\Plugins sub-folder.

Then launch aviutl.exe.
Drag-and-Drop your video file on to the main window
Then access the NL-Mean setting panel through:
Settings>NL-Means Light for GPU Type-C

Tick the check box on the top right corner;
Set all the parameters to their highest value, except the last two.
For the last parameter, "Protection", set it to zero or a small value below 50.

Finally, encode your video by:
File> Export with Plugin
and choose one of the encoder...
x264/QSVEnc/x265

I get a d3d11.dll not found error.

Try to get a Win7 machine with a decent graphics card (support pixel shader 3.0)to run.
If you are already running Win7, reinstall DirectX11.

There are similar denoise filters that work on XP and does not require video card, but they are the trimmed down version and do not work as well as this.

Are you saying this won't run on an XP machine?

[MaverickTse]

You can try ignoring the error and go ahead trying out the NL-Mean plugin. Should work unless you use resize(AVX), AFS or QSVEnc(QuickSync).
or wait for a few days while I am going to release a new pack, in Win7 and XP versions separately.

[poisondeathray]

The original non GPU version of NLMeansCL is called TNLMeans in avisynth . It will work in XP

TNLMeans

Can you clarify, is your pack a separate download from the Aviutl download link that's in the tools section here?

I should do what to install the version that works with XP?

As of v1.4, The archives on my site should be the same as videohelp.com.(you can check the MD5 hash if in doubt.)
If you are using WinXP, get the XP one, then just unzip to somewhere(e.g. My Documents or Desktop).
Then execute the only exe file in the larger folder.

Once I install the one labeled AviUtl_ExtraPack1-4[XP]Release, is there any need for the one labeled AviUtl-ENG1.30Extra ?

No. Ignore it, as it is the old version. Every EP stands on its own.

Okay - I really appreciate all your assistance. The new version so far is loading with no problem.

[PuzZLeR]

You can do it with Neat Video. All depends on what you define as your noise profile. In this case I had to do two passes, one for the pinkish streaks, and another for the off-reds.

You can compromise with the Y (luma) channel on this one - more color adjustment at the cost of (maybe) some detail. You can indeed remove all the color streaks, but the picture may look a bit smoother (however, you may be able to achieve it all with a bit of time and nitpickiness).

[PuzZLeR]

If you want to be picky after the fact, you can play around with some color filters, such as VirtualDub's Color Mill on the adjusted video to give it a more natural feel (especially since that red was giving me an eye sore).



Either way, this was to give you an idea, since there are probably millions of other combinations you can play with (gamma, levels, etc), but the new image may still need more streak removal (and will likely never look very good).
