Preview is not corrects. Problems with rings after noise rem

I have a flat colored wall example, where after noise removal, rings appear because of GRADIENT on the wall.

Normaly those rings are removed with ADDING grain. In this case, I would probably need to leave some noise in the scene. Am I right?

But the problem is, that rings are not seen in the NV preview windows, where you set up the amounts of the effect.

Rings DO appear in preview window of PREMIERE, rendered or not, and also on final rendered project on FULL HD TV.

ALL images are seen at

Please send a small test project with a short (1-2 seconds) clip to support [at] neatvideo.com

We will run the project on our test machines and will check what is causing the banding.

It is possible that the problem is related to the output codec used in the project.

Ok, I will send it. Thanx!
I doubt that is the codec, since the preview in Premiere has nothing to do with codec, and FINAL RENDER for HD TV was made with multiple export options / codecs:
- h.264 MP4 (highest quality render checked)
- MPEG2 blue-ray

I found out that I CAN NOT send you project file, since the original clip (m2ts file) is 50 MB big. Even if I cut it in premiere, I would still need to send you the original file with the project.
Any suggestions?

WOUU!
When prepering the project for you I found out what the problem is and it is not in your plugin! Sorry....

Rings appear, because I have Contrast and Shadow/highlight plugins AFTER NV and that makes rings visible. If I turne them off, rings disapear.

Sorry again.

Now I have to find the solution, how to make picture look good without gettings "the rings". :)
