avi to dvd problem

[NosT]

after i had converted my avi to dvd with cce 2.70 i could see that there are some parts of the movie that are not quality as the others.
see picture...

anyone can help?

What bitrate did you use when reencoding?
How does that same frame look if you take it from your source AVI?
To me, it seems like a too low bitrate, either when the AVI was encoded, or the mpg was encoded.

the bitrate i used is: 1,211 its small because i want to make a 3 movies dvd... but the quality shouldn't drop so low
here is the picture from the original avi

OK, so the source is fine - @1.211 kbps I'd say VCD resolution is max - If you've done it full D1 res, it's way too low bitrate.

but almost all of the movie the quality is fine...
its just one part
what bitrate is recomnded?

[mats.hogberg]

For full DVD res - no less than 4000 kbps, I'd say.
You'll see this kind of problem where there are much movement in the picture - the difference between 2 frames is big. Lower resolution lets you get by with lower bitrate. 1/2 D1 (352*480 NTSC) @ 2000 kbps will mostly be OK, VCD res (352*240 NTSC) below 1500 kbps will work (but that's really a too low resolution anyway).
Discs are cheap - You shouldn't be! Use 1 DVD/movie.

thx u very much mats for helpin...
the thing is...
the movie res is not full dvd res is about 720/400 ntsc..
i have black borders...
and if the quality will be a bit less good i dont mind... but there is a big diffrence in here...

Another rule of thumb is to use 4* AVI bitrate (if it's an XviD/DivX AVI) to make the source full justice when encoding to DVD mpg. How to resize any resolution AVI to anything can be found out with FitCD.
