Hmm, I didn't know that :P What's the disadvantage of using "mt_masktools-26.dll" on Avisynth 2.5.8? It worked for me.

EDIT: Thanks for the answer Gavino.
EDIT2: I took a screenshot with mt_masktools-25.dll and one with mt_masktools-26.dll, and the frames were identical (binary).

I'm using the bet2u version with nnedi3, nns=3, and lossless=3 and I must say the output is nothing less than magical. I'm using all the SSE3 versions of the plugins but I'm not sure if they are better to use than the SSE2 versions since I've heard many stories in regards to the stability of SSE3. Also I'm curious to know how MCBobUv6 compares to TempGaussMC_beta2u. Thanks!

With all respect, I would suggest that you change the name of your name of your modification to TempGaussMC_beta2'Something-or-other'.
IMHO, TempGaussMC_beta'x' should be reserved for official updates by the author, Didee. Then there is a clear distinction between official versions and unofficial modifications thereof.....of which there are a number floating about. I'm sure he and others would agree.

Can I ask what was changed? It's not immediately obvious.

Fixed chroma shifting 'cause in "josey well" MVtools it's not fixed yet, AFAIK, and added a parameter to change rfilter method. It works for me. ^^

Best regards.

Since this is still in beta state I was wondering whether it defaults to reasonable values yet. Can I just call "TempGaussMC_beta2()" in my script and get reasonable results, or are input parameters expected?

It would have been nice of you to retain the original appereance of the avs, now its a pain in the rear end to read. And perhaps the letter z is not the best choice if someone else wants to add to it as "z" is the last English letter. Try "w".

Look at the script and see what the parameters mean. Then decide if you want to change them. The explanations are quite clear.

Does anyone know how to deinterlace this one? I can't determine its field order.

^Looks like a video/telecine hybrid. I'd suggest using TIVTC with Hint=true and experiment with different hybrid modes in tdecimate.

I was replying to a thread over on Videohelp and started doing some testing with TGMC with various settings to determine speed impact. I have the results summarized over on Videohelp if anyone is interested. I didn't record the final bitrate (which I should have) and didn't look at each of the videos to determine quality. I did look at the default settings and the minimum settings tdeint (#5), as well as a few others. The shimmer that I was trying to get rid of was addressed to my satisfaction with all the ones that I looked at. Obviously, different sources and personal preference will determine what you can live with.

Quick summary here:
1080i PBS HD broadcast of Story of India
converting with x264 (r1602) @ default preset (not x264 limited)
avs file:
Code:
setmtmode(5,0)
MPEG2Source("Path\To\Story.of.India.E1-clip.d2v",cpu=3)
setmtmode(2)
lanczosresize(1280, height)
TempGaussMC_beta2(1,1,0,0,0,0,edimode="tdeint",Smode=1,SLmode=1,Sbb=1,SVthin=0.0,pelsearch=1)
srestore(frate=25)
lanczosresize(width, 720)
removegrain(1)
*modified my version of TGMC to use tdeint because 64bit yadif wasn't available at the time

Results table attached.

Ok, I am trying to find an easy way to determine the relative amount of flicker for various deinterlace methods. I saw the example floating around some time ago for the Stockholm sequence (4 horizontally stacked videos). That shows it very well for that sequence since it has only panning motion. On a more normal case (TV show/movie), the flickering isn't always so obvious. I have been playing around with overlay and subtract a bit. If I take a clip that I convert with TGMC (baseline settings) and then subtract another clip that I converted with tdeint or yadif, is it the flashing/strobing luma that is referred to as bob shimmer? If so, that method seems to highlight effect well. Just trying to make sure that I am not misleading myself.

I am hoping to use this method to 'detune' TGMC and compare to a default clip to verify that I haven't lost the de-flickering ability in TGMC.

Ok, did another pass at TGMC fps by settings. This time a little more systemically and without extra filters in avisynth to skew the results.

Most of these tests were run on a Q6600, 4gb RAM, Vista64 using Avisynth64 and x264_r1629_x64. The results for EEDI2, NNEDI and nnedi2 were run on my dual core laptop using Avisynth32 (2.5.8MT) and x264. For some reason the EEDI2 pass on my desktop crashed half way through, so I don't have those results and NNEDI and nnedi2 have not been compiled for 64bit. I re-ran run#6 (defaults with bicubic) and used the fps from that run to interpolate the fps for EEDI2, NNEDI and nnedi2 at dual core speeds. Based on fps results from the halfway point of the 64bit EEDI2 run, it looks like the fps could be ~3% slower on the 32bit system.

At any rate, my avs file was simple as was my x264 command line (speed would be a little faster without the ssim/psnr calls):
Code:
setmtmode(5,0)
MPEG2Source("video1.d2v")
setmtmode(2)
TempGaussMC_beta2(2,2,1,4,0,4,edimode="EEDI2",Smode=2,SLmode=2,Sbb=1,SVthin=1.0,pelsearch=2)
Code:
x264 --crf 18 --ssim --psnr -o video.mp4 video.avs 2>video.log
TGMC settings were changed as per the following table.


I have included the fps results from x264 and used the default settings to baseline the change in speed. I have included the resultant bitrate so you can get a feel for compressability and also included x264 ssim and psnr results (for what they are worth). I have also included what I am going to be using as my "default" TGMC settings (run19) for converting NTSC DVDs of PAL video.

when someone is dealing with small 'unstable areas' (which you could see after using TGMC) you can try following:
put the green code between the bold original TGMC`s code.
functions GlobalMOCO and LUTDeCrawl are needed. I changed the LUTDeCrawl a litte by adding a global motion compensation line to it.
http://www.aquilinestudios.org/scrip...-20081003.avsi
the masking part is stolen from idontknow whos script.

you got more stable result, a little blurring in some affected areads, and about 4% better compressibilty on clips i have tested (for --crf 22)
speeddown or speedloss not tested.

Hello guys,

recently I filmed with my MiniDV Camcorder and now, rather accidentally, I noticed some strange artefacts that TempGauss produces. It is a shot of a house, me standing on the other side of the road filming, when a person on a bike rides by. The rim of the bike causes some sort of "temporal smearing" or ghosting.

The footage was filmed with a Sony DCR-TRV 33E at a very high shutter speed (probably above 1/2000), so the motion is without any motion blur and super sharp.

Here is a screen shot of the problem:

Code:
Avisource("Bike.avi")
assumeBFF() #just to make sure
TempGaussMC_beta2(2,2,0, 4,0,4, lossless=-1, edimode="nnedi2", SVthin=0)
And here is the clip (DV AVI, unprocessed):
http://www.mediafire.com/?2hxylynmumz

I already tried different TGMC settings, but nothing really helped too much.

I don't really need to have this deinterlaced because I'm storing it on DVD, but for scientific purposes - and because I'm curious - I'd like to know if there are any solutions
for this issue.

Absolutely zero blending on your clip using tempgaussmc_alpha3().

On TempGaussMC_beta2, I see blending just like you.

Cheers,
David.

No time for deeper elaboration.

Basically, MVTools is missing the correct motion on the bike's rims.


@2Bdecided

With "absolutely zero blending", you're leaning a little far out of the window. alpha3 is not 100% free of blending. It's more like 90% only. (But I don't like such percentage numbers.)

And of course, beta2 can do the same. I told that in the past, and the fact hasn't changed since.

-----------------
tempgaussmc_alpha3(2,2,0,edimode="eedi2")
==
tempgaussmc_beta2(2,2,0,12,0,1,"eedi2",SLmode=1)
-----------------

The repair triple "12,0,1" is the exact equivalent of rep0/rep1 hardcoded in alpha3.
SLmode=1 is the limiting mode hardcoded in alpha 3.


OTOH, alpha3 has a lot more bob flicker. (Due to spatial limiting, which is a lame method generally.)


Suggestion: (not much tested, just a quick try)

-----------------
tempgaussmc_beta2(2,2,0,12,12,0,"eedi2",SLmode=2,search=5,searchparam=8,dct=5)
-----------------

This avoids blending as alpha3 does, but has less bob shimmer than alpha3, and (slightly) more/sharper/morestable detail.

Didée, I know you told me before - I haven't forgotten - but I'd already tried two approaches to find one that worked - further experimentation was left as an exercise for the reader! I knew you'd be along soon enough to give good advice.

Cheers,
David.
