50% in VD plug-in corresponds to 1.5 in a script.
-100% -> 0.0
+150% -> 2.5

No, NV uses something else, so it would require rewriting from scratch for that processor. Besides, even if we would use Intel libraries, there would anyway be something done using custom code separate from those libraries and that would have to be rewritten.

Yes, a dedicated FP array processor could accelerate NV filtration. The trouble is that such a processor is not standard part of modern personal computers so not everyone could benefit if NV would support this array processor. Supporting such a non-standard device could be quite expensive in terms o...

I am glad you are getting good results with NV. Regarding finding a large enough area for analysis, resizing the video frame changes the noise properties so you have to be careful. For example, if you build a profile using a resized (larger) frame then the profile will describe the noise properties ...

As far as I remember VD cannot provide interlaced frames to plug-ins in general. I believe interlaced video data is deinterlaced by VD before sending a frame to a plug-in so you have a choice "deinterlace using method A vs deinterlace using method B" rather than "deinterlace vs don't ...

Actually, the current version (1.5) will work with interlaced footage but deinterlacing implicitly done by VD in this case is not so high quality as that provided by the dedicated "deinterlace" filter, so you may still want to explicitly deinterlace video sequence using "deinterlace&q...

Yes, the lag depends on the filter settings. Specifically, it is equal to the Temporal filter radius.

It seems the deinterlace filter is already good enough in VirtualDub so bobbing is not really needed. Thanks a lot for sharing the results!

This is a question of deinterlacing methods in general. I did not try the field bob filter for deinterlacing. The standard "deinterlace" filter in VirtualDub seems to work very well as it is and it provides good basis for accurate noise reduction in NV. If you try the field bob filter plea...

Neat Video v1.5 plug-ins for After Effects, for Premiere Pro / Elements, and for VirtualDub are available What is new in this version of Neat Video: Adaptive filtration Neat Video can now automatically adjust its filters to the changing noise in different parts of a video sequence. This improves th...

Does it ask you to enter the registration if you use Neat Video and VirtualDub alone, without Avid? Do you work as an administrator on your computer?

Please contact support at neatvideo.com by e-mail and we will try to resolve this issue with your computer.

Thank you,

It is possible that the noise profile is not accurately describing the actual noise in that video. Could you provide a short sample together with the noise profile and filter preset you use? This would directly show what is causing the trouble.

Thank you,

Hi, Janos. Thank you for the suggestions regarding automated profiling. Yes, we are working on this aspect of NV functionality and I expect there will be certain new features in the next updates to automatically adjust the filter to changing video footage. It is going to significantly facilitate pro...

Thank you for the suggestions. I am adding these to the wish list.

Kind regards,

I think it is better to not compress in VD if you have enough disk space to store uncompressed version of the video.
