Avoiding Doubble encoding losses when making DVD disks from uncompressed AVI files.
TEMPNULBOX
Please if anyone knows how to Burn a DVD so that the data from an
uncompressed AVI file 720X480 can be burned to a DVD without
compressing it twice, tell me what program can do that.
Right now, I am converting BMP frames and WAV sound into an
uncompressed AVI file. The uncompressed AVI file is then converted into
a MPG2, which itself looks OK in media player.
The DVD burning software seems to not accept the uncompressed AVI as a
source file, but will accept the MPG2 conversion as a source file. The
burning software then RE-ENCODES the MPG2 file which should not be need
since that file should be in DVD-MPG2 format already. The re-encoding
makes the image look fuzzy and burned out when the DVD is played back.
So what I want to know, is there any DVD burning program that can do
one of two things:
1) Burn DVD directly from Uncompressed AVI files making just one
encoding, or
2) Is there a DVD Burning program that can brun a DVD-MPG2 file without
re-encoding it a second time?
Since the uncompressed DVD files are too large to have an hour worth on
the harddisk at one time, choice 2) may be the only one that could
work, that is find a burning program that does not need to re-encode
the MPG2 file before burning it to the disk.
Any help of ideas on how to avoid re-encoding of files to be burned to
a DVD will be helpful,
Thank you.

Nero has a bad reputaion for reencoding...

Probably so, but this is a bad idea, imho. I believe that one should
check each point of progress in making the DVD. i.e., Create DVD
compliant mpeg-2, author DVD VIDEO_TS folder, shrink/create .ISO DVD
file, then burn to blank DVD.

Many. My favorite is TmpgEnc DVD Author. Another is DVD Lab Pro.
There is the freeware DVD GUI Author. ULEAD Movie Factory 5 has an
option to not reencode.
DVD Shrink and ImgBurn are freeware programs for creating/shrinking the
authored DVD and then burning to the blank DVD. Both are available at
www.mrbass.org.

Thanks for the information, I am glad you understood the issue, I hope
with your help that I can make a DVD that looks as good as the DVD-MPG2
file playing from the computer *.mpg file.

Who/what are you replying to?
Authoring the DVD should not effect the MPEG video data.
Some players are better than others though, and the video
can have a pronounced difference in appearance when played
back on a TV as opposed to on a computer monitor.

program that re-encodes, is a form of abuse.

The only program I have that works with my DVD burner seems to re-
endode the DVD-MPG2 data. I will need to upgrade my computer to be
able to try the programs sugested by the other replies, which I intend
to do when I can manage the funds to do that.
Another related issue is the wide variation in the quality of the
results using different encoders for the same data rate. At the same
one hour per 4.7GB DVD the quality varies from one encoder to
another. All of the encoders I have tried seem very much inferior to
what some commercial DVD disks look like.
So my question is, what encoder is best, and what encoders are used to
make commercial movie studios use for making the DVDs of movies like
"Matrix" and the restoration of "Day the Earth Stood Still"?
I am starting with uncompressed AVI files made from 720x480x24bpp
frames taken down from 2048x1536x24bpp frame files.
Thanks for any ideas of how to get a DVD that looks as good as the
ones made by the movie studios?

If I were you, I'd start at digitalfaq.com. Especially the "Understanding
Your Source" section.

looked that over, but did not find the exact workflow diagram for that
software the motion pictures studios use to make DVD disks of major
film releases like the "Matrix", if that information is there please
help me find it with the full URL so I can look the workflow diagram
over to get the names of the software and encoders used. I am sorry
that I was not more clear in what I was asking, I will try again.
I am converting uncompressed 2048x1536 frame images down to 720x480
frame images in un-compressed BMP 24bpp, these in turn are made into
an uncompressed 24fps AVI file. The un-compressed 24fps AVI file
looks as it should.
When the un-compressed 24fps AVI file is made into a DVD-MPEG2 file
the result does not look as good from the stand point of the encoder
artifacts as some comercial DVD disks I have compaired the results
to. The artifacts I see in the various DVD-MPEG2 files I have encoded
with different encoders from the SAME un-compressed 24fps AVI file
look different, indicating that the encoders are producing different
artifacts from the same source images.
What I was asking was, does anyone know specific names of the DVD-
MPEG2 encoders used to make the "Matrix" DVDs and the DVD of the
restored version of "Day the Earth Stood Still" and also other major
hollywood titles?
If you know someone who works in Hollywood making DVDs for major
studios, please ask them what DVD-MPEG2 encoder that they used for
some major hollywood release, and what the title of the movie they
encoded was so I can look at the results on the DVD of various
encoders and pick the one I like.
Short of that, does anyone who has seen differences between encoders
see an encoder that works better than the others in having fewer
compression artifacts at the one hour per DVD rate?
I know the artifacts vary with compression, that is not what I am
asking about, the quality of the encoding seems to vary for other
reasons, some of which may not be adjustable to the user of the
encoder, i.e. were set internally when the encoder was written. So in
order to get an encoder that uses the same initial values as the
encoder used by the major hollywood studios, it would seem simplest to
just use the same software that they use...
So, if you know someone who does encoding of major motion pictures at
major studios, please ask them for me exactly what programs they use
for encoding DVD-MPEG2.
Once I get a DVD-MPEG2 file that plays well, I can try to burn a DVD
without re-encoding and see what that looks like, but if my DVD-MPEG2
file looks full of artifacts those are not going to improve much by
burning them to a DVD even if the DVD player has better filters.
Garbage in Garbage out, I cannot make a good DVD from DVD-MPEG2 files
that themselves do not look good. The problem is not the direct
result of the source files I am using, nor does the uncompressed 24fps
AVI file look bad, only after the encoding to DVD-MPEG2 do the
encoding artifacts make a mess out of the images, more so it seems
than in major hollywood 24fps films on DVD, so I think the specific
encoder or filters used by the major hollywood studions may play a
part in the amount of artifacts that get added to the images. If I
can try the same tools that they use then I can remove one of the
unknowns in the quest to match the results obtained by the major
hollywood studios.
Please know that I deeply appreciate all the answers I have gotten on
this subject so far, but I need to get results that look as good as
the major hollywood studio DVDs, and since they have done it there
must be some way that I can also, unless they are using software that
is not available for purchase? In order to find out if I can purchase
the software they use I first need to find out what they use, or at
least what will work exactly as well...
