When denoising with NV, there's sometimes appears a grid in areas of no motion and solid color. Usually on areas with less or no noise. This isn't really a problem or annoying, just wanted to let you know if you weren't aware, because this might bug videophiles or companies who need their videos flawless.

Which version of NV is it (which host application)? Still Demo edition of NV, is that correct?

Thank you,
Vlad

Yeah, with Virtualdub.

I guess you use an older version. Please try the latest one. And also, non-Demo versions should be better too.

After doing some renders I too see this gridding pattern. Kind of looks like looking through a small screen door.

I have the latest versions of FCP, Quicktime, NV, OSX.

I've noticed that selecting the Adaptive Filtration helps a little with getting rid of the small grid pattern. Again, sometimes it's noticeable and other times not as much. I'll try compressing for DVD/Blu-Ray and see if I can notice it projected onto a big screen.

Could you send me a project allowing to reproduce the effect please? When we see it directly, we can determine what is causing it and find a solution.

Thank you,

Hi NVTeam,

I'm still going to hold judgment on the gridding issue (which may not be an issue at all). We all know how Mac has a gamma issue and I want to be sure that there really is a problem first; I'll be compressing later this week and then I will see). Even though I'm using the Matrox MXO on a second ACD I'm not overly confident that WYSIWYG.

I will follow up with this. I am pleased to say that the results I'm getting with the Mac version are better than what I got with the PC version and then importing into Mac (which could actually be a codec issue when exporting out of Premiere with the DVCPRO HD codec). Fortunately I erased my Windows drive and re-NV'd my old clips.

Hi, I just wanna say that I no longer had this problem when I switched to the latest version, but it wasn't really annoying especially after compressing with a codec it became even less noticeable.
