Is it possible? I am currently using tmpeg, but I can surely see
artifacts and loss of quality when going from DV video into Mpeg DVD
format. Whats the best software etc? How come commercial DVDS looks
so much better?

In a word: No. DV uses much lower compression (5:1) than
any DVD format. It takes ~13GB to store an hour of DV while
DVDs hold only ~4.7MB per side/layer. You do the math to
see why there is more compression (and the artifacts that come
from that compression).

That is the source of endless debate.

They use varible compression where they "budget" data space
depending on how much compression each scene can tolerate.
You can compress the snot out of a scene of fluffy white clouds
in a blue sky, but lots of fine detail and/or fast movement would
require more data to faithfully reproduce.

Note also that commercial DVDs start with a better-quality
picture (lower noise, etc.) Unless you remove the kind of low-
level noise that many take for granted in amateur footage, it
takes wasted bandwidth to preserve that useless junk.

Hi!

I think you just opened a pandora's box..........

It depends on about a million and one things!

As others have stipulated, you will lose some quality, lossy compression
scheme (in your case, MPEG-2 DVD) result in output having less details than
the original. How much ? Depends on the settings of your encoder and on
the quality out your source footage.......

Why do commercial DVDs looks better ?

Simple! Mainly because of the source material! Because they are not
shooted using 500$ MiniDV camcorder! (Not even 3000$ ones!) They are film
shooted with 50,000$ dollars equipement with hi-quality lens that cost
sometimes even more! The filming is done with proper lighting, did you ?
Did you shoot handheld or one a tripod ? They are a lot of people figuring
all the proper need for a shoot! After that, come the post-processing,
expert colour correction, and a lot of other thing...........

The outcome is that consumer MiniDV produced DVD cannot be as good as big
buck's Hollywood top house production! You are comparing two different
thing's here!

But if you want to, you can come out with some pretty good quality DVDs from
MiniDV footage if you plan a bit in advance what you shoot, and afterward's
if you want to "post-process" before actually burning the DVD.

They are a lot of tutorial on the web about getting the best out of MiniDV.
Look around............

As for myself, I post process from a "bit" to "very much" depending on the
quality of the source video. They are a lot of things to think about when
"manipulating" video to produce good DVDs. I don't know what your level of
knowledge is, but I very much invite you to search and
experiment............... A LOT !!!

You might want to post the settings that you are using. You should be able
to get minimal and even unnoticable degradation by using VBR 2 pass at a
reasonably high bitrate (6-8mbps).
