DVD quality on 1CD 700mb

[Suhoi]

I saw so many movies with dvd quality on a single 700mb cd and i wonder how was encoded. Personaly i succed to encode with dvd quality but on 2 cd. Every time when i try to encode on a single cd....the result quality was not to good. I use GKnot and Divx 3.11 alpha.
Any sugestion r welcomed.
10x!

For the maximum quality you will have to get a lot of experience and encode the same movie with different settings. You will get a "feeling" for the best settings depending on the type of movie.

Here are some simple rules:

- cut off ALL black borders
- reduce the resolution till you get a bitperpixel-value above 0.15, with a low bitrate a 512x.. may look much better than 640x..
- use filters to smooth the video for better compression
- For really low bitrates it may also be usefull to reduce the framerate to the half.
- normalize the sound. If the sound is normalized you can lower the audiobitrate. Normalized mp3-sound at 112kbps sounds better than un-nornmalized at 128kbps. Some also don't have many stereo-effects and sound good even if you convert them to mono-sound.

Hmm...i will try .....
I usualy use 0.20 bitperpixel-value for one cd and 0.27 for 2cd. My sound file r 128kbps and aprox 100mb soze

Bitperpixel depends very much on the kind of movie. Lots of action need higher values but with some movies with less action look even good with 0.15. I always try to use not more than 10% of the bitrate for the audio. With a normal 700MB-cdr this would be 70MB for the audio.
A interesting way for lowering the resolution may be to resize a video in example from 640x360 to 320x360 and us BS-player to resize the encoded video back to 640x360. For me it seems to look as good as 512x288 with a lower number of pixels.

I always use the same definition :
576x320 for 16/9 movies and
576x432 for 4/3 movies.

Then, it depends of the length of the movie. If it's more than 80/90 min, no hope to get good quality on a single CD with this definition, so I use 2 CDs.

With those rules, I personnaly can't see the difference between my DivX and the original DVD, and I'm using a big 82cm 16/9 TV.

I'm working with Codec 4.12, always using 2 pass encoding (GKnot)

Good luck !

LaFouine, i saw Rush Hour2, Snach, Romeo Must die...all this movie i think that r close to 2 hours long.....and i saw it one a single cd and the quality was very,very good. I tryed to encode Dirty Dancing who is 90 minutes long with a small resolution....but no DVD quality on a single cd. Maybe Divx3.11 is the cause?

[LaFouine]

What is the resolution you use ?
What is the final bitrate GKnot applies ?
You told sound is encoded at 128 kps, true ?

Can you give us those informations ?

Normally DivX3.11 can give you perfect results...

I used fast motion and got DVD quality for 435MB, on low motion scenes, it was east is east.

I did the same thing with aliens. perfect

I also used low motion on east is east, perfect quality for 699MB same as fast motion

excellent quality!!!!

I use Xmpeg 4.2a (because less bugs) and divx 5.02...full picture (720 * 432)
two pass encoding (less than 7 hours to all encode)
the film is on 2 cds 700 (about 1000 or 1200Mo) and the rest is for the addons (making of, ...)

I use MDVD to play automaticaly with high processing and to make a menu in .avi

The quality is excellent, and you can't find a difference when you watch your screen 17p with a distance of 40cm of your eyes!!

and all the features are on the 2 cds!! with chapters, languages, subtitles, addons, and all that you want

[LaFouine]

MicroDVD is really great, hu ?

I do the same as you do.... perfectionnists we are...

[cho]

perfectionnist !!!

hu ?? what's meaning?

YES, MDVD is very great!! do you use it ???

I explain:
With it, I succeed in making 2 or 3 cds and to watch the film in one!!
MDVD accept 3 parts for a .avi with each extern languages(I use wma to have no pb of synchronisation movie/sound)

1.on the first cd, you program as the 2 or 3 cds are in the same directory in your hard disk.
So if you copy the 2 or 3 cds in the same directory, you can watch all the film in one with all subtitles, langages of each part ( it is transparent for you, it works very fine), menu, addons...

2.with the other, you program MDVD to watch each part with each menu, subtitles, langages, and others if it's on this cd!!

so, to resume, you copy the 2 or 3 cds on your hard disk, you can watch like the DVD all the parts in one with menu like DVD! and otherwise you put each cd one after one, MDVD begin automaticaly each time, you select with the mouse in the movie-menu what you want!!

it's very easy to use after,

aussi : MDVD accepts to switch subtitles and languages when you play the movie...
