Always wrong size ....

[xebone]

Hi !
Im using Auto GK 2.16b and xvid.
I set (.mpg file 600 MB) to xvid (200MB) but i get 113 MB and another trial i got with other source material 130 MB - so bad quality also ....

What to do ?! ANy ideas ? I also read already checked FAQ and if my xvid install is clean.
Looks nice. I even uninstalled Divx so that there cant be any colision.
Any tool with that i can check if my xvid install is perfect and not anyhow disturbed ?

When i got "preview" the quality is perfect, when the encoding is done, its bad ...

Any ideas ?! Please !

We haven't seen your log, so we have to guess. My guess is that your sample is already at its maximum bitrate.

But unless you take the time to :logfile: that remains just a guess.

[xebone]

My sample ?
You mean my source ? Its . pva so a dvb-s source.
Quality is pretty high and good ...

Here the logfile. Hopefully it helps ;o) Source was 3 time as big as the target is, so about 580 MB ....

The undersizing is a source of concern but I am not surprised about the bad quality. The compressibility percentage is very low. 720x544 @ 180 MB won't be a pretty sight + you are reencoding.

Which version of XviD? The one bundled with the latest AGK? If not, can you update to AGK v2.18b + the XviD bundled and give it one more shot to see if the undersizing goes away?

[xebone]

>>The compressibility percentage is very low. 720x544 @ 180 MB won't be a pretty sight + you are reencoding.

How can i stay at the given resolution ? So no reencode?

SOurce is 720x576@580MB - Final is 720x544@180MB
Normally a 1/3 is always perfect quality .... always was like this before.
Dont know why its so awful then here ?! :o(


I downloaded latest version of xvid XviD-1.1.0-Beta2-04042005.exe
2.18b+ isnt downloadable all mirrors saying "error". Besides i havent had that problems with a prior version (about 1/2 year old one) but dont know anymore which one that was.

And its still not clear why it makes a 130MB file instead of 180MB as i wanted ....

[jggimi]

I found a few things in the log... Note first these restrictions:[29.09.2005 17:56:47] Target size: 180Mb
[29.09.2005 17:56:47] Custom resolution settings: fixed width of 720 pixels
[29.09.2005 17:56:47] Custom audio settings: VBR MP3 with average bitrate: 160KbpsAudio will consume approximately 24MB of that 180MB file
Because of the fixed resolution, take a look at these compression results...[29.09.2005 18:02:55] Compressibility percentage is: 24,22
[29.09.2005 18:02:55] Using softer resizer.
[29.09.2005 18:02:55] Chosen resolution is: 720x544 ( AR: 1,32 )
[29.09.2005 18:02:55] Predicted comptest value is: 25,12That's a terrible compression ratio, and explains the poor quality of the output.

My newest guess is that an XviD was installed on top of an existing XviD installation. That can cause size symptoms such as what you're experiencing. Try de-installing every XviD completely, then re-installing XviD.

[xebone]

Yeah i know i wanted to keep 720x resolution. Btw. outputfile is 130MB only i wanted 180MB ...
The main question is WHY is the compression ratio that bad then ?! Mpg should be very good compressable ....at least that much

Yeah i did - many times xvid installation over xvid ...
Is there any tool to check if all xvids are gone ? I mean all dlls and such ?
Or how can i check manually ?

Do i have to restart after deinstallation before i reinstall xvid?

[jggimi]

Yeah i know i wanted to keep 720x resolution. Btw. outputfile is 130MB only i wanted 180MB ...Exactly. And improper installation, or an overlayed, installation, can cause this symptom.The main question is WHY is the compression ratio that bad then ?! Mpg should be very good compressable ....at least that much...If the codec isn't behaving properly, that could be one reason. Another possibility is the content. It doesn't matter that your source was MPEG -- compressibility varies by what makes up the pictures. Motion, color, movement (both of photographed content and the camera) are only some of many factors that affect compressibility.Yeah i did - many times xvid installation over xvid ... Don't....Do i have to restart after deinstallation before i reinstall xvid?No.

[xebone]

Hmm im pretty kinda giving up ....

Deinstalled xvid over the "uninstall.exe" and it was gone.
Then restart. And then install of xvid.

Made it 720x again -> compressibility 25 .... there i already aborted it thats too low. When i let it make "auto width" then it makes it something like 492x
then compressibility gives 55 or something like that.

Source material is "king of queens" which came on TV. So if u know that show, you know there is no fast motion, no special colors or something like that.
1/3 in size should be possible without loosing seeable quality - at least that worked on many other King of queen episodes i encoded ....
How can i stop the reencoding and still make 2-pass ?!

Im confused ... and no real solution here seems.

Any ideas how to 100% clean xvid off the system ?
Can it be that there is a rest of xvid somewhere even when uninstalled ?

(sorry no i cant reinstall windows now ...)

thnx for your help!

One usually doesn't need to use anything other than the Windows uninstaller for removing XviD, but just in case it doesn't work for you - use an extended uninstaller, one that will scan and delete folders, files and registry settings left behind by the regular uninstall utility. I use Your Uninstaller! 2005 PRO v 5.0.0.117 (don't use the Windows one at all), but this is paidware. For your purpose, try to grab a fully functional trial version of a similar utility from www.download.com. Check under Utilities-->Uninstallers.

That said, maybe you should also look into other possibilities why the picture is bad. What about decoding? What are you using to decode the avi? ffdshow? XviD? If ffdshow, do you have post-processing or something turned on?

[woah!]

how about you let autogk decide for itself all the settings and see if it comes out the wrong size. i bet its dead on when you do. i think you are asking to much at 720x480 4/3 full size at 180meg.

i would say 512x384 is about right for 180meg sizing.

[chilled]

i think you are asking to much at 720x480 4/3 full size at 180meg.

me too. TV captures are usually noisy (therefore less compressible) and giving 720 with 180 megs delivers you a very low comp ratio.

many sources look much better encoded at lower resolution but higher bitrates (or same bitrate but for lower resolution) but it seems you still got a problem as AGK should use the given 180 mb as comp percentage is so low

[xebone]

>>how about you let autogk decide for itself all the settings and see if it comes out the wrong size. i bet its dead on when you do

Did it now another way - gave % of quality instead of size.
So i did 40% - and result is 195MB size and quality is pretty good.
So lowering to 180MB wouldnt make it that bad as it was with given 180MB and resulted in 130MB ....
And my TV pictures arent noisy - its DVB-S Sattelite _digital_ TV. Its perfect clean. Here is the log. So in my opinion its proven that there is any fault with that "size thing". Really strange.

btw, for MTK compatibility you can't use any version of XviD - ONLY the one bundled with AutoGK. See FAQ Q 4.3

[xebone]

FINALLY ! ;o)))))))))
THnx len0x - file size is 179 MB now as i wanted 180MB - and the quality is PERFECT now.
I deinstalled xvid that i installed normally and installed the 2.18b incl. the bundled xvid and finally it works so it seems the MTK compatibility was the reason it hasnt worked right before. Thank you very much to all ! Compressibility was 52 now ... i even could go lower like 160MB .... WHich value is the one where it gets worse ? 40 ?

Here the log of it. Ahh the last question how can i stay at 720x576 ? It always reencodes to 720x544 .....

Compressibility was 52 now ... i even could go lower like 160MB .... WHich value is the one where it gets worse ? 40 ?


I would not go under 50 in any case. For normal clean material 60 is the lower bound. But I'm not doing captures...

Ahh the last question how can i stay at 720x576 ? It always reencodes to 720x544 .....


720x576 is not a proper AR (i.e. not 4:3), so why would you want to keep it?

Ok seems you have pretty high quality needs - i think 50 is perfect even with 45 its still very very good ... but ofc sure depends when you use a DVD as source quality with 50 will be on the lower end ....

Why i wanna keep it ? Cause reencodeing makes the quality worse, and thats the format the dvb-s stream is ....

Read this: http://www.doom9.org/aspectratios.htm and if after that you want to keep your encodes anamorphic(i.e. distorted) then enable original AR in hidden options.

P.S. If you can't see the difference between 50% and 75% of quality then you either have pretty bad captures or bad TV/monitor :)
