Rendering speed, birate

What burning speed should I use when I make DVD? 1 or 2
Birate.... I read, the higher the better if I have room on the DVD disk. It starts at 8000, so what would be "Higher the better"? increment of how many.....

Thanks ChristerTX.... I managed to burn my first DVD, menus. sub menus etc and the best is that it plays on my DVD player.... only I find that the video quality is not what it should be.... Is it because I start with HI-8 and not digital?

So, thanks to ATHERYN for the step by step, explanations in How to :Render with Movie Studio for DVD Architect, 1/16/2005
A N D all threads.... below

I succeeded in burning a DVD that plays on my DVD player.... So, I think any one can succeed if I did.....

>>only I find that the video quality is not what it should be<<

The picture quality of the MPEG-2 Template in Movie Studio is just awful. It softens the image and blends the fields into a mess. I encode the video directly in DVD Architect - If I have to render out to MPEG-2 before making the DVD, I use Premiere to render an 8mbp/s bitstream. Also, since the standard MPEG-2 template can't be adjusted, no inverse telecine can be applied leading to a 20% coding inefficency for film-based sources.

Disclord,
Do you mean that the rendering process is better in DVDAS than MVS 4?

Higher bitrates may not be better. Generally you don't gain any improvement in video quality at bitrates above 8,000 Kb/s except possibly for very fast action scenes. The max video bitrate thats allowed is 9,800 Kb/s. When you try to approach the maximum video bitrate you start crowding other things (like audio and subtitles if you use them) because there's an overall aggregate maximum that can't be exceeded .

Also keep in mind that because burned media reflectivity characteristics are quite different from stamped media, that you can actually create playback problems with high bit rates. Higher bit rates have a tendency to create higher read errors which can create problems for some players. Some folks recommend not exceeding 7,000 Kb/s. Personally I find 6,000 Kb/s quite fine for most material.

Commercially produced DVDs from Hollywood are very frequently down in the 5,000 Kb/s range for average (they can do this because they have very, very good MPEG encoders and they can also tweak the bit rate according to the scene requirements).

Here is an article that deals with bitrates - http://www.digitalfaq.com/capture/avivsmpeg.htm
There is a lot of good info on that site
