General discussion

Optura 600 to DVD quality

Jan 6, 2006 3:13AM PST

Connected through S-video to my HD monitor the picture is widesceen but interlaced and average quality. Burned fromm AVI to DVD (Adobe Premiere Elements 2) the picture is a little better on my progressive scan DVD player using component outputs. How do commercial DVD makes make the picture so sharp?

A related question: is converting the AVI files to VOB files on the DVD higher or lower quality than converting to MPEG-2 or MPEG-4?

Thanks!

Never mind. Apparently .vob files are mpeg-2.

Comm'l DVD quality
Jan 6, 2006 5:42AM PST

First off, commercial DVDs are not "burned" like we mere mortals do at home. They are "pressed" from a glass master (typically) so they can make thousands of discs instantly. But, the digital files orginate from original film transfer material (we mortals have no access to this material), the commercial discs are dual-layer (we can use these too), and the comm'l discs use advanced compression technology to produce the MPEG2 DVDs. Their compression technology is more advanced than anything Vegas or DVD Studio Pro generates for home use. Creating content for commercial DVDs is a multi-million dollar business.

The video sources of commercial DVDs are shot by the video camera that cost over ten thausand dollars, the DVD quality is depend on the video source.

Camcorder reviews: what test is used?
Jan 9, 2006 10:32PM PST

A related question then is: when popular web sites review video performance what tests do they use? Do they always use the same rendering software for consistency's sake and what software is that? Do they review the AVI rendering on their computer or do they actually burn a DVD or create an MPEG file and compare the quality that way? Do they always use digital inputs and outputs and stay away from composite?

You have to find out from the source (web, magazine, etc)

what their testing techniques are. They do not all use the same techniques.
