Neat Video & Neat Image community

I'm using NV3 and upgraded to NV4 for Davinci Resolve.
NV3 has perfect accuracy of temporal filter (especially with radius=5)
NV4 does blurry spots, lost details and result look far worse than preview.

Sorry for big picture.


My Cuda 5.2 videocard is not supported in NV3 and nextgen version works inaccuracy.

1. Make sure you build the noise profile correctly, that is most important.

2. Check preview inside Resolve's window, not in Neat Video, because Resolve does not provide all input frames required to prepare accurate preview (specifically, the temporal filter cannot work without those missing input frames). In Resolve preview, the filter is able to receive all input frames and prepare correctly processed preview.

Thank you,

Noise profile is correct. I'm using NV for years and purchased 3 copies.

NV3 temporal filter works perfect without losing details but CUDA 5.2 unsupported.
NV4 is unacceptable because of that blurry areas with losing details.

In another topic you say you plan to include CUDA 5.2 support in the next regular update for NV3. Is it cancelled?

thanks

Please prepare a reproducible test case - a small project showing both NV3 and NV4 on a short test clip. We will run it on our machines and check what exactly is causing the problem. It most likely can be avoided or fixed.
Please send that test case to support [at] neatvideo.com

If you want to try v3 with 5.2 support please also send a request to support [at] neatvideo.com

thanks!
downloaded new version of NV3. It works!

I'll prepare for you test on next week.

I'm interested to see the results of this investigation.

Sorry for delay. I will do it soon. Too much work (almost done).

I'm here!

No effect


NV4 no temporal


NV4 temporal=5


NV3 temporal=5 (same noise mask)


NV3 is cleaner and details much better

I can do more samples if you need.

Thank you for the test case.

To compare results like this they have to be prepared based on the same noise profiles and with the same filter settings. We will download the files and check if these conditions are satisfied in the test project.

Thank you,

We have opened the test project and found that:
- there supposed to be two clips in the timeline but only one clip is actually present for testing;

- there are no effects added to these clips, so there are no any instances of NV4 or NV3;

- so there is no way for us to directly see/reproduce the results you posted yet NV4 or NV3 are not in the test project yet.


Could you please add instance(s) of NV to the clip or clips and then configure them the way you did to get the screenshots you posted?

Then we would be able to directly reproduce your results on our machines. Without that, we do not know what kind of noise profiles you built, what filter settings you used, etc.

Thank you,
Vlad
