My other suggestion is more generic, and not specific to VDub.
I think having a black & white (or Y only) mode could be interesting.
This mode would work this way :
- Process only Y channel => speed improvement. Cb and Cr channel simply put to 0 (or 128).
- In manual tuning, no message about "clipping" or "non uniform" on Cb/Cr channel, even if
there is, beacause they'll be erased !
The purpose is, as you may have guessed, to work on old black and white movies.
In this case, building noise information on Cb/Cr channels, and spending time
to process them is totaly irrelevent.
Second suggestion : A black & white mode
Thank you for the suggestion.
Having a dedicated grayscale mode could be useful, especially if that was directly supported by plug-in hosts.
However, even the current version of Neat Video can used to efficiently process grayscale video data represented as RGB:
- if you set the noise reduction amounts in the Cr and Cb channels to 0% then the filter will only filter the Y channel and will work faster;
- the clipping / non uniform warnings related to the Cr and Cb channels can simply be ignored when you know that you work with grascale videodata;
- the filtration results will be as good as with a dedicated grayscale mode.
Kind regards,
Vlad

Re: Second suggestion : A black & white mode
I re-suggest this, mostly to avoid "Not Uniform Cr Cb" message in a Black and White movie, i've used Greyscale (avisynth script) before sending to NV.
