TMPGEnc bitrate hell...

[Guest]

Hi All:

I am trying to convert a 120 minute DVD into a single VCD, but am
having a major problem. I've checked videohelp.com, various FAQs and
past Usenet posts for information regarding my problem, but have had
no luck. Here is the procedure I am using:

1) Use DVD Decrypter to rip the DVD onto the hard drive in VOB format.
2) Use DVD2AVI to rip the audio stream in WAV format from the VOB
files and create a d2v project file.
3) Use TMPGEnc to read the d2v project file, the WAV audio, and create
mpeg 1 files with a bitrate allowing 120 minutes to fit on 1 CD-R 74
min (650 MB)
4) Use Nero to create the menu and burn the VCD.

I have calculated that for 120 minutes to fit on 1 CD-R (650 MB), the
average (or constant) bitrate for the MPEG 1 files needs to be < 740
kbs. (i.e., I am using bitrates of 128 audio + 600 video)

The problem I am having is that no matter what audio and video
bitrates I manually set in TMPGEnc, the resulting MPEG 1 files from
the VOB files always have the bitrate of 1374 kbs (1150 video
(default) + 224 audio (default). What's the point of hardcoding
constant audio and video bitrates if TMPGENc is simply going to ingore
them?

I guess my questions are:

1) I thought that a VCD could be authored with any amount of video
time on it, as the bitrate was used to dictate how much video could be
put on. Is it possible to create a VCD on a 650 MB CD-R with more than
70-74 minutes of video (1374 kbs bitrate)?

2) What do I need to do in TMPGENc to enable it to encode an aribrary
d2v project based on my EXACT bitrate specifications?

Thanks in advance for any help.

Yes, but it isnt a VCD since VCD has CBR audio and video and set bitrates.
You can call it kvcd, or xvcd that tells you its out of spec.

Why not just let dvd2svcd do it for you in vcd mode?

It will use Canopus, Tmpegenc, or CCE depnding on your config, and will
allow for non-standard settings for most anything.

That is probably because you have "Stream Type" set to "MPEG-1 Video CD"
under the System tab. I think it will automatically pad the video. Use one
of the 3 other MPEG1 presets. I forget which one would be the correct one,
but try it on a small sample to find out. I think "MPEG-1 System
(Automatic)" should do the trick

Thanks for this info. Does this mean that I should strictly stick to
the VCD standard (1150/224), otherwise my xvcd or kvcd will not be
recognized by most, if not all, stand alone DVD players?

I tried all afternoon and some of the evening to get dvd2svcd to work
for me. Even after installing CCE, dvd2svcd didn't recognize it on my
system. When dvd2svcd used TMPGEnc to do the encoding, no audio was
present in the result. With all the problems I'm having with TMPGEnc
on my system anyway, it's not really a surprise to me that dvd2svcd
didn't have much luck with it either.

Thanks again for the help...

Thanks. This did the trick. I was able to create all my MPG-1 files to
total < 650 MB based on your suggestion. However, when I added them to
a VCD project in Nero, Nero reprocesses them to a much larger size.
I've heard that you can burn 740 MB onto a 650 MB VCD but Nero made
the files much larger than 800 MB. It looks like Nero won't create a
"xvcd" or "kvcd", only standard VCDs based on the 1150/224
specification.

In Nero, when you choose "Video CD" and try to add your video, you
should get a popup that says you have problems, and it asks you "how
do you want to continue?" Click on "Turn Off Standard Compliance and
Continue."

Nero is perfectly happy to burn a KVCD without re-encoding. I don't have a
copy of Nero installed at the moment, so I can't give you the specifics on
how to do it, but it's definitely possible. Check your optioms. There must
be some compliance or re-encoding parameters you can disable.

You can fit about 800mb on a 700mb/80min CD.

Point 1: ¿how do you know the bitrates attained by the Tmpgenc
encoding?

Point 2: there's no reason why Tmpgenc should not obey.

But first, I would like to know about point 1 before proceeding on to
point 2.

When you add a non-standard mpeg file to the compilation, Nero
complains. Just tell it is allright, and that it should make a
non-standard Vcd.

Wether it is going to work on the desktop DVD player, is another thing
altogether...

That's true. Most DVD players should be able to handle it, though. It's
usually non-standard resolutions and high bitrates that will cause problems.
Low bitrates are usually not a problem..

I have done about 100 KVCD VCD's and haven't had a single problem with my
Panasonic DVD player reading. I use TMPGEnc and Nero. I am guessing that
unless one has an off brand or really cheap DVD player or an old one that
you shouldn't have any problems with them reading such a disc.

The new Tmpgenc, 3.0 I think, is pretty amazing, you just tell it what
output size you want and dump as many files into the mix as you want and
at the end it's all ready to be burned, I'm not sure how functional the
demo is but you should download it ad check it out.
