Encoding problems buring captured DV to DVD

Question

I'm using the Roxio USB dongle and Creator 2010 (all current updates) to capture S-video from a Hi8 camera. Since the camera is from pre hi-def times, it should be 4:3 aspect ratio.

 

I've been experimenting with capture resolutions to see which one looks best on my high-def TV when burned to DVD. Unfortunately, all of the DVD quality capture modes result in an unacceptable amount of distortion/pixellation when a burned DVD is viewed on the TV. I'm capturing only a 2 minute test clip, so in the burn process no additional compression is needed to get the clip captured in the various quality modes to fit on the DVD.

 

I've also tried the DV capture mode. It results in the best overall quality picture in terms of minimal/no pixellation in the original .avi image, but when it is burned to DVD the resulting clip has distortions in it where sections of rapid motion induce horizontal distortions (seel below). These distortion bands go away when there is relatively little motion in the video.

 

So I have two questions.

 

1) When doing capture in one of the DVD quality modes, is there any way to control aspects of encoder quality/compression beyond the simple selection of 'DVD HQ', 'DVD LP', etc, to improve the image quality in these modes?

 

2) Any ideas on how to eliminate the distortion artifact introduced when burning a distortion free AVI file (captured with 'DV' quality) to DVD (original quality, space to spare on the DVD)? More on the artifact I'm seeing when doing this: The distortion on the DVD looks like horizontal pulling of the image to the right in three bands. The first is about 1/3 of the way from the top, the 2nd is about 1/2 way from the top, and the last is right at the bottom. The bands are about 1/10 of the entire picture height in width. The shift is smooth about a central line that is shifted most, and then shifts less on each side until there is no shift outside the band, e.g., something like this at a pixel level (I've used '_' instead of spaces as the spaces are removed when posted):

Don't know what a slang 'dongle is supposed to be but the rest sounds like you have the Roxio Video Capture USB device and probably Creator 2010 SE…

 

DV is the highest you will get and is un-compressed.

 

DV HQ is equal but compressed. If recompressed a couple of times in post processing, it will degrade.

 

Output can never be better than input but without choosing a specific output in MyDVD you are rolling the dice!

 

I always set to HQ or at the least SP. "Same as original" is new option in 2010 but we really haven't played enough to see what it can do.

 

One problem with higher outputs when combined with lower captures is they look worse! You cannot render up to a higher quality and get good results.

 

Ratios are fixed and not something you can magically change.

 

The Roxio USB device will only capture in 4:3.

 

MyDVD outputs in whatever the source files is.

 

VideoWave must be set to the file ratio being used – 4:3 or 16:9 or funny things happen.

 

That is an overview – you will probably still have questions.
