VcMohan has a similar type plugin, FFTQuiver (or similar) and it also has 1D version (which I think this uses [fy=0 in all cases]),
dont know if can be directly converted, but if can then I am guessing that it could be quicker (even if the plugin 2D version is slower, dont know if so).
I think it also has (from memory) the ability to supply some kind of mask which allows to select frequencies (2D version).
Anyway, might be worth a look.

The one issue I see that keeps this script from being useful, even in its current state, is the odd tendency to put green at the edges and purple in the middle
I just tried the version I posted last and it doesn't seem to have this problem.

Just had a look at Cmx5,

Whites are sometimes too white (glaring, ie 'burnt out'), we lost some colors that were previously correct, but cant help that (Dr Who green swamp grass).
Center pink mostly gone. Green edges better. (perhaps due to high frequencies on frame edge), other green areas seem to mostly have disappeared.
Overall, better, methinks (Shirley is still gold, and that is all that really matters ).
Now mainly sepia recolor replacement alternative (BUT better, and consistent).

Nice job.

EDIT: Dr W, at 1:00 extra presence of greenish tinge, methinks maybe responsible for the 'burnt out' whites, perhaps slight reduction in
green if possible.
EDIT: Perhaps need some kind of legal YUV restrictor (some YUV combos do not convert to RGB, eg Y=$FF, U=$81, pure white +
additional U).

EDIT: Green edges are not a problem, thats what crop is for.
EDIT: Pinkish Daleks seem to be a thing of the past

EDIT: Green edges, perhaps add some Padding.
Code:
function Padding(clip c, int left, int top, int right, int bottom) {
    # Didee: http://forum.doom9.org/showthread.php?p=1596804#post1596804
    # eg, Padding(32,32,0,0).Padding(0,0,32,32)
    w = c.width()
    h = c.height()
    c.pointresize( w+left+right, h+top+bottom, -left, -top, w+left+right, h+top+bottom )
}

No more green borders (at all).

EDIT: Added DownSz Bool. Without down size likely fewer higher frequencies, maybe less noise
EDIT: or maybe more high freq ?, is SincResize sharp ?
EDIT: Added Pad Int.
EDIT: Definite difference (ClipDelta) between DownSz True/False, but cant really see it.
EDIT: Doc W, 2:30, change in fringing evident around the doctor with DownSz=False, not sure if better or worse,
also seems to be change in skin color.
EDIT: Some things seem a little more orange with DownSz=False, and more blue(looking white) with DownSz=True.

Can anyone else verify same ? (They seem to just happen randomly, works ok one minute, next run exact same script crash)

I can't reproduce your problem but please try this version of defreq. It's an ICL11 build, also a bit faster than the original.

Thatks Groucho, but crash on 3rd run with this.

Code:
Avisource("Doctor.avi")
crop(0,0,-2,-2)             # Non mod 4
SAT=0.33
GrayScale
Cmx7Mod
Return Last
got to dash bus coming in 3 mins.

I can reproduce it now on XP32. Before I was on XP64 where I couldn't make it crash. Odd.

}
function cmx (clip c)

c=c.greyscale()
merge(c.turnleft().cma().turnright(),c.cma())
return last
}
Edit: Very much improved. May work...
Edit: Updated to use new version of F2Quiver...
Experimental, uses F2Quiver, I would suggest using HQDN3D at max on chroma. Needs more work...

MW, I will try that, but not this day.
This day is for rest and relaxation, (that and its now 03:15, need some sleep).
Just the same, take a look at prev script, works quite well apart from the crashes.
Ill get to cmx presently. Peace Bro.
Also, did you try 1D FFTQuiver thing, no go ?

G2004, I'll maybe come back, gorra get some shut eye.
Come back already, G, does that look like Defreq bug to you (I was not sure enough and did not want to cry WOLF !!!)
EDIT: It was actually doin it a bit a few days back but I dismissed it as an MPC peculiarity, without even looking at error report.
(MPC sometime is a bit annoying).

The Licensing hours in this country are so very very bad, but at least they dont shut at 22:30 hours any more.
Everywhere else, seems to be so much more civilized (you can get drunk as a skunk, and for longer).
22:30 hrs, I once saw a guy drink 5 bottles of Newcastle Brown Ale (Brown Dog ) in 20 mins, just to fulfill his
evenings quota before time was called.
(Them woz the daze).

I played around with it for a while. The crashes are random and appear to be related to the multiple calls to defreq. Replacing the last 2 or 3 defreq calls with dummies and it won't crash.

I find you are using the older version of FFTQuiver plugin. Results may not be different with newer version.

MW, I shall be using the v2.6 version FFTQuiver from here:- http://www.avisynth.nl/users/vcmohan/
(current cmx does not work with it.

EDIT: Cmx7Mod., Tried older FFTW.dll same problem.

Current FFTW.dll, Using VDub current on Duel Core Core Duo 2.4Ghz, Plays about realtime speed for about 2 seconds, and freezes
for about 1 second, repeatedly (although has not as yet crashed in VDub current).

At least as it curently stands, think Cmx7Mod provides more hopeful future (if bug can be fixed, tried fftw.dll v3.0.1, as supplied by my original FFT3DFilter, same access violations).

Here cmx modified a bit.

Code:
Function cmx(clip c, Float "Sat",Int "Pad") { # (c) MWilson, http://forum.doom9.org/showthread.php?t=173364
    # Progressive Only : MUST be MOD 4 Width and Height, Otherwise will crop Mod 4 (F2Quiver limitation)
    Function cmx_Lo_Level(clip v,Int Pad) {
        # Parmameters in bunches of 5, 
        # 1) Symmetry.   [1, Circular, 2. Horizontal, 3, Vertical, 4. Linear Fan, 5. Point].
        # 2) Type.       [1. low cut, 2. High cut, 3. Band Pass, 4, Band stop, 5. Notch].
        # 3) Notch freq, [low freq of band, or X freq of point or angle1 for linear fan].
        # 4) High freq of band, or angle2 for linear fan, or y freq of point.
        # 5) Degree of Shaprness.  0 to 24. If 0 Gaussian filter otherwise Butterworth filter is designed.         
        r=v.F2Quiver(2,2, 39, 47,0,                   3,3,100,188,0,  rescale=false,frad=16)
        g=v.F2Quiver(2,3,118,128,0,                   3,2, 74,128,0,  rescale=false,frad=64)
        b=v.F2Quiver(2,2, 96,128,0,   2,3,128,130,0,  3,3,74,128,0,   rescale=false,frad=64)
        mergergb(r,g,b)             # Result is TV Levels RGB, 16 -> 235
        (Pad > 0) ? crop(pad,pad,-pad,-pad) : NOP               # Must remove padding before autolevels    
        autolevels()                # Stretch 0 -> 255
        ConvertToYV12               # TV Levels YV12               
        coloryuv(autowhite=true)    # Center chroma
        tweak(sat=3.5,interp=32)    # pump up sat
    }
    Sat    = Default(Sat,0.33)                                                                    # Default 0.33, 0.0 -> 1.0
    Pad    = (Default(Pad,4)+1)/2*2                                                               # Round up next multiple of 2, Avoid green border.
    c = c.Crop(0,0,c.Width/4*4,c.Height/4*4).ConvertToYV12.GrayScale
    smallc = c.sincresize(512,512)
    smallc = (Pad>0)  ? smallc.pointresize(smallc.Width+Pad*2,smallc.Height+Pad*2,-Pad,-Pad,smallc.Width+Pad*2,smallc.Height+Pad*2) : smallc
    chroma_1 = smallc.cmx_Lo_Level(Pad)
    chroma_2 = smallc.turnleft().cmx_Lo_Level(Pad).turnright()
    merge(chroma_1,chroma_2)
    lanczos4resize(c.width,c.height)
    c.mergechroma(last,Sat)        
    return last
}

Avisource("Doctor.avi")

cmx(Pad=8)
Quite a bit of fringing.

EDIT: Made a couple of small changes.

EDIT: RaffRiff42, Cmx7Mod is quite a bit better than Cmx5Mod (if you dont count Access Violations in Defreq).

Gaussian filters which you are using in F2Quiver are supposed to deliver outputs with no or least ringing. Butterworth as sharpness increases results in more ringing.
I read in one of the posts of freezing of frames. This may be because of multiple calls to FFTW3 dll in 2.6 version. Instead of avisynth 2.6 if you use avisynth+, either 32 bit or 64 bit versions and FFTQuiver is designed to work in multi thread mode under it. Most likely freezes may not occur. The following lines of code may be added to script after loading plugins
SetFilterMTMode("F1Qiver",2)
SetFilterMTMode("F2Qiver",2)
SetFilterMTMode("F2QTest",3)
SetFilterMTMode("F1QTest", MT_SERIALIZED)

OK, then someone else should take over script cleanups/mods, I use neither Avisynth+ nor MT.

Freezing is much more evident in Defreq Cmx7Mod script (along with the access violations).
EDIT: Although when not freezing Cmx7Mod plays at almost realtime speed on my sedate running Core Duo 2.4GHz m/c.
FFTQuiver cmx runs a lot more slowly. [EDIT: May be due to use of AutoLevels]

EDIT: MWilson, you seem to be using vertical symmetry (mode 3) along with TurnLeft/TurnRight, is this really as intended ?

Just tried compile Defreq using VS 6.0.
Replaced Avisynth header VERSION 2, with VERSION 3 (v2.58),
and also replaced old Info.h with IanB refactored version of Oct 2010.

Still have Access Violations in Release dll, but not in Debug dll (Debug dll almost as fast as release for Cmx7Mod).

I'll see if v2.6 Avisynth VERSION 6 header makes any difference.

EDIT: Nope, still crashes on exit from v2.6 compiled DeFreq (release mode).

EDIT: In v2.6 Debug dll, get and awful lot of these identical messages to debug window
Code:
First-chance exception in VirtualDubMod.exe (KERNEL32.DLL): 0xE06D7363: Microsoft C++ Exception.
And by 'Awful Lot' I mean hundreds, is that 'Normal' ? (still seems to run alright though)

EDIT: Darn it, getting the odd crash (on close) in Debug dll.
