Black Bars in Both Sides of my SKVCD?

digitall.doc · #1 11-04-2003, 06:02 PM

Hi all:
first time I post in this forum. I tried to look for the answer making use of Search, but with SVCD I got 344 matches...

too much to read (I think Shibumi had a problem like mine, but didn't post if he could resolve it). Well, here I go:
I want to make a KVCD from a camcorder capture, that is a 720x576 m2v file. As I get an average bitrate of 2700 with calcumatic, I want to make a S(K)VCD.
I'm using the MA script adapted for interlaced sources. I crop and resize with Moviestacker and BicubicResize. I use the KVCD 352x576 MPEG2 template. But when I make an mpg test file (directly from TMPGEnc Stream type: system (video only)), I get a square film in hte center of my TV screen

, with big black bars on both sides, and I think that the image is vertically stretched.
It also happened with my first MPEG1 KVCDs, but I learned to change Video Source Aspect ratio to 4:3 625 lines (PAL) and Aspecto ratio to 4:3 in TMPGEnc, and this way I got nice KVCD. But this settings are not working with my S(K)VCD.

Am I doing anything wrong?. Should I just make the m2v file in TMPGEnc and then multiplex my tests with BBMPEG?.

Please, give me a help.

Maybe wrong settings ....
Please post your script .... that will discover everything.
And by the way, if you let moviestacker do the resizing job, choose in TmpgEnc "center"!

sounds like the same prob as mine,I couldnt get it to work in an avs script but managed it by just using tmpgenc with the kvcdx3 template no probs.The source I had was really good quality and I didnt mind not using any filters.If anyone can show a sample script of how to make the image the full width of the screen in an avs script I would be grateful

Hi all:
Shibumi, you're right: if I set the size to the native video, that is 720x576, it looks ok on TV. But I can´t put it in a 80 min CD, that's the reason I have to convert it to 352x576.
Incredible: I tested several scripts, that didn't work.
Script 1:

LoadPlugin("D:\KVCD\Filtro25\STMedianFilter.dll")
LoadPlugin("D:\KVCD\Filtro25\unfilter.dll")

LoadPlugin("D:\KVCD\Filtro25\undot.dll")
LoadPlugin("D:\KVCD\Filtro25\TomsMoComp.dll")
nf = 0

asharp(1, 4)
BicubicResize(512, 560, 0, 0.6, 9, 0, 702, 576)
STMedianFilter(3, 3, 1, 1)
MergeChroma(blur(1.50))
MergeLuma(blur(0.1))
SwitchThreshold = (Width<=352) ? 4 : (Width<=480) ? 3 : 2
ScriptClip("nf = YDifferenceToNext()"+chr(13)+ "nf >= SwitchThreshold ? \
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) ")
AddBorders(8, 8, 8, 8 )
LetterBox(18,18,0,0)
function fmin( int f1, int f2) {
return ( f1<f2 ) ? f1 : f2
}

Script 2:

even=SelectEven().ScriptClip("nf=YDifferenceToNext ()"+chr(13)+"nf>=SwitchThreshold?unfilter(-(fmin(round(nf)*2,100)),-(fmin(round(nf)*2,100))):TemporalSoften(fmin(round (2/nf),6),round(1/nf),round(3/nf),0,2)")
odd=SelectOdd().ScriptClip("nf=YDifferenceToNext() "+chr(13)+"nf>=SwitchThreshold?unfilter(-(fmin(round(nf)*2,100)),-(fmin(round(nf)*2,100))):TemporalSoften(fmin(round (2/nf),6),round(1/nf),round(3/nf),0,2)")
Interleave(even,odd)
Weave()
AddBorders(8, 8, 8, 8 )
LetterBox(18,18,0,0)
function fmin( int f1, int f2) {
return ( f1<f2 ) ? f1 : f2
}

I don't think the problem is in the script, because script1 is the same I use frequently, with no problem. I found the problem after begining to work with mpeg2. Is there any setting in TMPGEnc I have to change?.
Wait your suggestions.

Check taht the arrange method is "Center" in TMPGEnc.

Dialhot: you're really fast.
I had this setting in full screen (keep aspect ratio), and worked for me in mpeg1. After reading your post, I tested it and the image, in TMPGEnc preview, looks vertically stretched. But as it happened also sometimes in mpeg1, and then looked well on TV, I will immediately encode a test and post here how it looks.
Thank you Phil, for your help.

I guess I did something wrong in my first tests. Following your advice Dialhot, I encoded with Arrange method set to Center... and there it was, perfect. But I also encoded again my previous samples, with Arrange method set to Full screen (keep aspect ratio)... and looked also perfect.
Thank you anyway, but stay connected 'cos I'm afraid all happened by chance, and maybe will happen again (...pesimistic today?). Noooo

Working fine. No problem at 352x576, neither at 528x576.

Thankyou

As you determined the correct final (legal) size in your script incl. added borders and so on ---- by this, refering to your encoding size, it is already "Full screen" when importing into TmpgEnc!
Thats why it gives you the same result
