KVCD: Little Video Pixelations?
 

Its not that the video isnt sharp and clear because it is its amazingly clear. However there was 2 little spots it just pixels up real quick....
Just like dvds do sometimes. Any clues?

Hi,
Come on Clessy...No more details :?:
Script, template, output size...
Give us means to understand and try to help :wink:

Re: Little Video Pixelations
 

You just answered yourself :arrow: "Just like dvds do sometimes" :!:
The only solution is to increase MAX bitrate.

:lol:
I was first :arrow: though maybe the guy can adjust something in it's package to produce better output :roll:

The bit rate os 2000 CQ 100.
Thats high enough to be constant especially how it did it when there was no movement at all on the screen.
And I know I should of posted the template and all that but its in the post I made just below this.
I'd really like to know the advantages of scripts but I just started this yesterday. I was using BBmpeg untill I realized it was well.... defanilty not for me.
When you ReMux in tmpegencPlus and it outputs as a mpg this is still keeping it in KVCD constrants right?

If someone understand something to what Clessy asked, can he unscramble it for me ? :-D

(no offense, just kidding).

Jerk :(
And it was my medium that caused the breakage in quality.
CDRW are worthless.

You should have mentioned that on your first post :mrgreen:

I'm still confussed I compared this to regular SVCD at the same bitrate and resolution and there excatly the same size....
I dont see how Somone fit all of pirates on one disk. God I wish that guy would give a Jpeg shot and spec cart on this Bitrate and audio quality.

For sure two files with the same bitrate are the same size ! Whatever the resolution (from VCD to DVD) this equation will be verified !

But perhaps you are not talking about file size. But in this case which size are you talking about?

Can you try to be a little less "fuzzy" in your posts ???

KVCD is supposed to be smaller than SVCD at the same bitrate.
All my test point out that its excatly the same with werid resolution settings and thats all...
I dont understand how people get whole movies on disk with bitrates of 2000. What am I doing wrong?

Not at all !
It is supposed to be BETTER at same bitrate.
And as it is better, we can use a LOWER bitrate and obtain THE SAME quality. That is how we put a whole movie a a single CD.

Whatever the codec (avi, mpeg, huffyuv...), whatever the size of the picture (from 32x32 pixels to 4800x4800 pixels), the filesize of a movie is ALWAYS : bitrate (in kbit/s) * length of the movie (in s) / 8 = size in KB.

THAT IS THE DEFINITION OF THE WORD BITRATE !
(number of bits that you will use to encode one a second of movie).

They start by reading KVCD guides. Did you ?

If you are encoding CBR at 2,000Kbps, that is what you are doing wrong :!:
You have to encode Variable Bitrate by using CQ or CQ_VBR mode, but you just can't use any CQ value. You must perform file size prediction, to take into consideration the content of the movie (action, drama, etc.), and then you'll get an optimal CQ value for your desired target.

You only have one Option on your Tmpegenc Templates. It says CQ.
You have Maxium and minimun. Action the max should be 2100 and the low 1900. I use that for just about everything tho but those seem to be the standard the "release" scene use's.

Be more clear what you're pointing to.

Ugh I'm a dumbass I dont even see where your talking about with these scripts? I havent even tired using a script or do I see where the guide is for it. :?:

KVCD is so much more complexed than other formats.

Good start. Really :!:
Where did you get that 1900 MIN :?:
There's no way you're going to get a movie in one CD-R with a MIN of 1,900Kbps :!:
The templates, if downloaded from this site, should have the MIN set to :arrow: 300Kbps
Only THEN you will have variable bitrate fluctuations between 300 and 2,100 ( should be MAX=2,000 if you use the current MA script) I just did :roll:

Erm like I said could you kindly just point me to what your writing these scripts in? I must be over looking this cruical step.

We all use AviSynth scripts. Look here: http://www.kvcd.net/forum/viewtopic.php?t=3483
The one mostly used is the one "For DVD and clean material ( for use ONLY with AviSynth 2.5x )"
With that script, there's no need to go beyond a MAX bitrate of 2000, but you should use a MIN of 300, or lower, if your standalone player supports it.
Then, with file size prediction, you'll be able to fit 2+ hours at 528x480 (KVCDx3) on one CD-R, easily.

I'm looking on thes script thing it will probably take me days before I understand it. I dont even under wtf avi encoding has to do with the mpeg at all.

Look here for some basics: http://www.avisynth.org/index.php?page=YourFirstScript

But you really don't have to understand the details of the script. It's documented, so you only have to basically change the line related to your file name, and the resolution you want.

And yes, it will take some reading to grasp it all, but after you understand how it works, you won't regret it and you'll never go back to the "standard" ways of encoding ;)

Edit: Here, for inspiration, this is what you'll get on a single CD-R:

Days?! I have used blindly AviSynth (GKnot) for 6 months before to begin even to understand something. There is a way to decrease this time - trying, testing, getting errors and testing and trying again all the day and all the night...
