Another look at neatvideo temporal denoise

[mammo1789]

I use neat video regularly on almost all my VHS sources, i must say that for chroma noise i yet to see better filter ( and i used a lot avisynth filters starting from cnr to fft3d and others ) to shame it is vdub filter and works in rgb. One thing i hear a lot is that its temporal part is not to the par to other filters like temporal degrain and mc temporal denoise.
I used one clip make color adjustments ( and proper color conversations ) used temporal degrain ( default ) vs neat video ( default temporal 3x 0+) i stack them horizontally and i made some screen shots and video it seems that ver 3 preserves more detail than previous versions and even better than temporal degrain i get the same ( almost ) with mc temporal denoise the difference with degrain is very minimal so it is still lower than neat although close. It seems that neat started to get hold with the heavy weight temporals out there so it starting to became very complete ( one size fit all ) denoiser and it becoming very fast too.

What do you guys think ?

Right side is neat by the way

NeatVideo is still my old standby for VHS, even if you have to be careful with settings (MCTemporalDenoise, TemporalDegrain, etc., are no exception to this rule). I often use it almost entirely as a temporal filtyer; it seems NV programmers have improved the motion analysis a bit in Version 3. Yes, going to RGB can be problem for many, but not if you make those conversions correctly and don't keep switching back and forth YUV>RGB>YUV>RGB, etc. ANything that requires heavy color correction is bound to be tweaked in RGB anyway, it's really difficult to isolate color areas in YUV (try fixing color in After Effects' Color Finesse plugin. It'll demonstrate the limits of working color in YUV, even if it's best to make basic corrections in YUV first).

I started using V3 about 3 months ago. Small but definite improvements. Certainly, I don't use NV for everything and it has its limits (try removing spots and rips with it. Won't work). But for what it can do, it's hard to beat.

BTW, thanks for your posts. but the proper term is "color conversion", not color "conversation". But, then, not many members here can use more than one language, and many can't can't even get that right.

I like the V3 but you can do better than neat v2-v3 as far as chroma is concerned imo. Download it from here if you're curious ( (pics included to compare neatv2-v3 etc..) http://www.mediafire.com/?a5y99fzzsfvzecb

thanks master it looks promising but it looks complicated too what plugins are mandatory and how is the speed

as a temporal filtyer;

Thanks sanlyn for your support concerning the right color correction ( especially the yuv correction first) i learned a lot from you, and master seems very guruish in avisynth scripts i guess thanks master

Well you need nlmeans gpu (you can replace it with ff3d if you want), fft3d, mvtools,GradFun2dbMod among other things, most of the filters are explicitly listed at the beginning so pay more attention. The part that does the magic here (well depending on content because i find it not that good for fast motion= lose detail) begins at a=last (and i'm not guru enough to change anything in there that would make sense as of yet)
