I've been playing "search" and I keep seeing talk about an Optimal Script... well, I can't find it anywhere? Anyone know where it can be found?

I tried it on 3 different movies, and I get a lot of flicker in the solid colored areas in the background. Is this normal?

Hi Shibblet,

No, that's not normal.
Maybe it's a color space issue
Are you using the latest version of AviSynth

1/ What is your source type ?
2/ Check that you are using K-Notch Matrix.
2bis/ What is your encoder ?

You're not using directshow filters to read your script are you?
That is, you did install ReadAVS.dll on your system so Tmpg can read *.avs scripts, right?
Otherwise it's a jungle out there when it comes to directshow filters...
Cheers

Holy underwear stains Batman! I've never used ReadAVS.dll in my life. I am going to have to go and get that one.

Any of the DirectDraw / DirectSound / DirectShow drivers seem to be quite a problem in just about any app.

Thanks, I'll give that one a try.

Then go ahead and download it from http://www.avisynth.org/warpenterprises/.
Unzip it.
Read the readme.txt.
Just copy the ReadAVS.dll and ReadAVS.reg to your Tmpgenc's directory.
Open the ReadAVS.reg with notepad.
Change it's last line to the Drive letter and full path (using double backslashes) of Tmpgenc's directory.
Save and close the *.reg file.
Double click on the *.reg file and answer yes when prompted to merge that information into your registry file.
Close and restart Tmpgenc, if running.
Open Tmpgenc's "Option>Environmental settings..." menu.
Open the "VFAPI plug-in" tab.
Check that the item "ReadAVS.dll" does not read something like "the file cannot be loaded.".
When configured properly it should read "Avisynth/VirtualDub script reader v0.1".
And last you can untick all options in that window besides "ReadAVS.dll" and "TMPGEnc.vfp" since most probably you won't need them.
Close and restart Tmpgenc, again so it saves the options.
Load your Avisynth script with TMPGEnc and happy encodings
Am I missing something here, guys
Cheers

Well, the flickering seems to be block noise. So it might be the compression, however, 70+ CQ is normally not an issue...

The ReadAVS.dll didn't seem to make that big of difference. And I am sure that I am using ReadAVS.dll instead of DirectShow.

Any other ideas?

Sure about that
Did you "Uncheck" " Directshow Multimedia Reader" in TMPEG

Positive about that one. The only things checked are

ReadAVS
DVD2AVI Project File Reader
TMPEG Project File Reader

Now, when I use the optimal script, and downsample to 352x240, I have noticed that every frame just before a scene change is incredibly blurry. Just one frame, that's weird. But it's just before every scene change. Maybe that will help with my problem.

This is the normal behaviour of the... very old MA script ! It was enhanced to reduce the phenomena. So either you use a very old MA script, either your eyes are eagle sharp

Nevertheless, I do not use ever the MA script because of that blurry "thing".

The script that I am using is the one from RDS's link. It's the one from the top of the forum. Is this the script that everyone is using? And if so, does anyone know what causes the flicker and blurred frames before scene changes?

Now that I've had plenty of testing, seems to me that this version of TMPEG almost twice as fast as it used to be.

Hey Shibblet ,
Don't use the 1st one.
That one is for old Avisynth 2.0.x.
Since I bet you're using Avisynth 2.5.5, use the 2nd one from that list.
And if you're not using Avisynth 2.5.5 yet, please upgrade ASAP .
Though, I'm not sure the blurrying has anything to do with the Avisynth release you're using and the script you're using.
Cheers

Right, I am using the one for AviSynth 2.5x and I still get that problem. I did make some minor alterations. I took out the Grip-sizing. Here, I'll post it.

Code:
LoadPlugin("D:\Video\MovieStacker\Filters\MPEG2Dec3.dll")  
LoadPlugin("D:\Video\MovieStacker\Filters\STMedianFilter.dll") 
LoadPlugin("D:\Video\MovieStacker\Filters\asharp.dll") 
LoadPlugin("D:\Video\MovieStacker\Filters\unfilter.dll") 
LoadPlugin("D:\Video\MovieStacker\Filters\undot.dll") 

Mpeg2Source("D:\Video\Rips\My Movie.d2v") 
 
undot() 
asharp(1, 4) 
BicubicResize(448, 256, 0, 0.6, 2, 59, 716, 358)
AddBorders(16, 112, 16, 112)
STMedianFilter(3, 3, 1, 1 ) 
MergeChroma(blur(1.5)) 
MergeLuma(blur(0.1)) 

ScriptClip("nf = YDifferenceToNext()" + chr(13) + "UnFilter( -(fmin(round(nf)*2, 100)), -(fmin(round(nf)*2, 100)) ). TemporalSoften( fmin(round(2/nf),6), round(1/nf), round(3/nf), 1, 1) ")

function fmin( int f1, int f2) { 
  return ( f1<f2 ) ? f1 : f2 
}
I prefer to do Bicubic resizing and make my black borders evenly divisible by 8. I kept the Linear Motion Adaptive Filtering, and that seems to be the problem with the blurry frames, and sometimes the flickering.
Any suggestions?

Of course the problem is in the MA part : that is the way the filtering is done (blurring a lot when the pictures change a lot, so at a scene change, that is a mess). That's what I told you already. And there is no solution except to stop using it, as I do (and as I once mentioned).

Dialhot:

Can you post a link to the thread that discusses YOUR latest optimal script?
