Compressing to create HI QUALITY DVDs Question –

Posted by Natasha O’cconor on July 23, 2008 at 3:55 am

I have read many many many threads related to this subject over the last few weeks. I am yet to find something that will help me even more…

FACTS-
I create DVDs for work with 16×9 hi-res material. Each piece of material is between 30-60sec long. I go from Compressor 3.0.3 then create the DVD in DVD Studio Pro 4.

With the material calculated in time, there is no more than 30min. I am using the 90min hi quality compressor DVD preset.
The material is not coming out great, it is ok but I need to try and make it better. Once I have gone through the process of actually making the DVD in Studio Pro the quality of the vision is standard. I need to try and make HIGH quality material not just standard.

Hi,

Can you tell me/us exactly what this “Hi-res” material is. I.E. how was it shot or generated? What format is it in? Frame size etc, as much information on the source material as possible please.
