Hi

I have an odd problem with the MA script. The opening credits to any movie I encode blink. Not on my computer, mind you, but only when played on either of my two DVD players. This is only when the background is black. If the background is scenery or whatever, the blinking stops. This does not happen when using the static script #4. I don't know about closing credits...I always cut them out.
Any idea why this happens?

Thanks

I Jim,
Best thing to do for a start is copying your script and paste it here on the forum and I mean the whole text of the script.
That way we can try your script and tell you our experiences with it.
BTW could you also tell us which version of Avisynth you're using?
Cheers

Here is the script...

---------------------------------------------------------------------
AviSource("D:\Avi\Movie.avi",false)
undot()
asharp(1, 4)
GripCrop(480, 576, overscan=2, source_anamorphic=false)
GripSize(resizer="BicubicResize")
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) ")

#
Blockbuster(method="noise",detail_min=1,detail_max =8,variance=0.3,seed=5623)
GripBorders()

## Functions ###

function fmin( int f1, int f2) {
return ( f1<f2 ) ? f1 : f2
}

###

----------------------------------------------------------------

Nothing special about it. It's the MA script with an avi source and a blockbuster line. I use AviSynth 2.5.4, latest TMPGEnc, Xvid codec is RC4 and the decoder is set to YV12.
Sometimes I don't use CQ in TMPGEnc. The newest version has a long-sustained format 2-pass VBR wizard. The benefit here is I can customize, I don't have to worry about file size prediction, and the quality is very good. Could this be the reason? Anyway, I'm trying the same video and script in CQ mode to see if the blinking still occurs.

Thanks

Hi Jim,
Yes I see your point.
I can't help you in this case Jim.
It's just a bit outside of my tiny knowledge.
We must wait that wiser guys come here and see you problem.
I have used that script over and over again (without the minor change avisource and the blockbuster).
I never had any issues with it, ever.
C ya

You don't have to use MA script with avi sources. You can use Dialhot V4 script. Give it a try and see if blinking is still on.

I'm using the MA script on the advice of Incredible. My AVI source is very high quality.

The blinking problem comes from TMPGEnc's 2-pass VBR long-sustained format encode method.
I thought I found a way of avoiding CQ prediction by using VBR. I guess not. Figures.

Thanks guys

I don't want to enter a debate with Inc (mostly because I don't have time to post a lot these days) but you SHOULDN'T (not musn't) use the MA script with ANY kind of already DCT based compressed source. Good or bad !

If your avi is a DV video, no problem. But if it is Xivd/Divx/3ivx/whatever MPEG4 you want, use a static script. This is due to the way these algo removes non critical info of the original source to compress them.

I do understand you very well Phil! And there has to be no debate. but you might let me post something as it would not be that good to leave that subject until you got time.
But if someone else does underline your point he can also act for you. As I do not say "Its like I do say" but Im following a logic and an experience of mine, ... thats all

DVD sources are ...based on mpeg2 yv12 streams ... therefore also based on DCT based compression like mpeg4! I think we agree in this point.

IF you got a veery good high quality backup in mpeg4 of your DVD (and we are talking here about exact that rare case)... means a quality like the orig. Also here MA (IMHO) can be used as it also bases on yv12 input.

Good or Bad??? Do you think I would use a such high filtering Optimalscript on a very exact clean mega detailed mpeg4 incl. not one "blocky" part etc?
And thats why I recommended to the starter of this thread to just "try" the MA on his source as optimal script (as he told) was filtering to heavy on his mega good source. I m not in doubt of your way (btw. you didnt understand it like this but just saying that in case of other participants of this thread)


So how do we have to "see" his problem in case of this "blinking".
So an answer cant be generally "leave MA" on mpeg4 (although in regular that would be right).

So I want to know the EXACT parameters of that Avisource:

- Content seems to be a movie
- is it still in a telecined state? means 29.97 (sorry if you already pointed that out but im here in that many threads so I do not remember)
- how do you encode later?? Means which encoder is used AND which settings are used! still interlacing was set in encoding options (Tmpgenc i.e.)... and so on!

The best would be to provide some seconds of that "credits" part of the ready encoded avi in here where these issues do occur ... then I can tell you what happens and if the probem could come from the Avisynth script OR from the later encoding process.

So do I. That's also why I told "shouldn't" and not "musn't".
Some advices are act of fact (like "Don't use space color convert when you can avoid it) and other are only opnions. Here it's my opinion to say "no MA script for MPEG4 source".

It's true that when I said "all DCT based compressed soruce" I was forgetting that DVD also are .
In fact I was thinking about "all MPEG4 based compressed source".

MPEG4 works a different way than MPEG2, but you already know that

Let say that it should be tested among others possibilities. A good surprise is always possible.

Okay, so we are saying all the same thing

Hi guys

My source is a 1.4Gb Xvid avi movie...23.976fps, non-interlaced, approx 1500Kbps. To me, that is high quality.
I followed Incredible's suggestion from another thread to try the MA script with the addition of minimal blockbusting because of some low light scenes. I also removed the asharp line from the MA script. I am quite pleased with the results.
My secondary problem, blinking credits, has been solved. See my previous post.
Is there a difference of opinion as to which script I should use?

Thanks

In fact that is far from hight quality. At most it's "high quality for a xvid".
Do remember that a "high quality" source is a DVD that is often more then 6 GB long and an AVG bitrate near 4500. DV avi take 320 MB per minute of movie (20 GB per hour). These are also hight quality.

It more a matter of knowing where to look at for the defaults. If the result is pleasant to your eyes, don't bother with all our advices and keep continue like you did.

In those terms, yes, there is a big difference in quality.

I will follow the suggestion here and revisit the static #4 script and compare. As you say, in the end I will let my eye decide.

Thanks
