HELP !!! Question for Vitualis !!!

[tastypoison]

Hey Vitualis...
You helped me out a while back in this thread:
https://www.videohelp.com/forum/viewtopic.php?t=135610&highlight=
to be able to figure out if an image would require overburn

Now I have run up against something even more confusing.
Lots of times, I use VCDImager to pull an svcd mpg out of a bin/cue so I can burn the cd with the title I choose, and include the nfo in the root directory.

However, I have now run up against some images that do not require overburn (per the info in the previous thread), but If I rip out the mpg, Nero says it won't fit on a cd. If I just burn the image with Nero, it doesn't complain at all.

How could the image not require overburn, but the extracted mpg file does???
Here is the relevent info for the image:
-------------------------------------------------------------------------------
VCDdebug - GNU VCDImager - (Super) Video CD Report
$Id: vcd_debug.c,v 1.33 2002/01/04 20:20:29 hvr Exp $

Source: image file `D:\TV\Star Trek\TOS SVCDs\1x02 - Charlie X - [dvdrip.svcd.Taz].bin'
Image size: 359688 sectors
SVCD detected
--DEBUG: found TRACKS.SVD signature at sector 185
--DEBUG: found SEARCH.DAT at sector 186
--DEBUG: found /EXT/SCANDATA.DAT at sector 225

Man, am I confused
Can you help clear this up for me?

Thanks

I could answer that, but since you asked for Vitualis....................

I don't use Nero much at all, but I presume that when you are authoring the SVCD with Nero, it may be remultiplexing/padding the MPEG file --> which can lead to inflated file sizes.

359688 sectors is just a sliver off 360000 sectors (= 80 minutes exactly) so if the file was padded even by a small amount, Nero may complain about the requirement of overburning.

This is all academic though... Just use VCDImager or VCDEasy or VCDImager Tools GUI to create a new CUE/BIN image and burn that... OR... let Nero overburn.

I must be missing something in the question , but my understanding of it is,
A mpeg up to 800Mb can be burnt if burnt a SVCD.
A mpeg extracted from a SVCD can only be if burnt if less 700Mb.

That would explain why the SVCD image burns fine but the mpeg contained in the image is too big to burn on it's own.

Probably all useless info.

That would have been my answer.

I assumed that the original person was trying to burn the ripped MPEG file with Nero as a SVCD in which case that wouldn't be the answer...

Yes, you are correct Vitualis. I was ripping the mpg out of the bin/cue with VCDImager, and then dropping the mpg into Nero in SVCD mode (That way I can include the nfo and name the disk as I choose). This has always worked in the past - if the image would fit on a disk, so would the ripped mpg. This was the first time I had an extracted mpg report as too large but the bin/cue burns with no warning.

So, now I'd like to know...Is there some software that would let me edit the contents of the original bin/cue before burning? If I could add an nfo inside the bin/cue, and modify the disk name as I wish, I wouldn't need to extract the mpg at all. I've looked at a few different programs, but they all seem concerned with getting files OUT of the bin/cue...I'd like to be able to ADD to the bin/cue.

Thanks

[vitualis]

You can't just "add" things to an image file. It doesn't work that way...

What you can do is to use the VCDXRIP tool in VCDImager ( or better, use VCDImager Tools GUI ) to extract everything from the S/VCD INCLUDING an XML descriptor file. Then, modify the XML descriptor file to your heart's content (e.g., putting in extra files, modifying the PBC, changing the disc name, etc): http://www.michaeltam.com

Then, use VCDXBUILD to create a new CUE/BIN image with your modifications.

Ok, I understand what you are saying, but if I extract the mpg from the original bin/cue and the extracted mpg gets reported as too large by Nero when I try to burn it directly, what good would it do to build a new bin/cue based on a file that is too large? Wouldn't the new bin/cue then be too large to burn as well?

Sorry if these are stupid questions...I've ripped out plenty of mpg's, and also burned plenty of bin/cue's, but I've never actually created a bin/cue of my own...never had the need to before.

Thanks

As I said before, the problem is probably because Nero is remultiplexing / padding the MPEG files.

Since the original S/VCD was probably made with VCDImager, you won't have this problem. In any case, even if the image does end up slightly larger, you shouldn't have too much problem overburning the disc.

Regards.
