Different Video quality after burning the DVD.

[suppafreak]

I am not sure if this is right place for the topic.

I captured video from VHS to PC using SCLive as AVI file. The quality of the VHS and the AVI file looked the same when played on TV. The AVI file was slightly edited (no filters applied) in Adobe Premiere Pro. Then the file was converted to MPEG-2 DV at 6 Mbits in Adobe MPG converter and 7 Mbits using Adobe Encore DVD transcoder. The MPEG quality looked the same to the VHS and AVI file when played on TV. However, when the MPEG file was burned to a DVD and played on TV the picture quality looked slightly over contrasted. I tried burning DVD using Adobe Encore and Roxio Media Maker 7.0, with no difference in the final DVD.

I am not sure if its transcoding, burning, or just Digital vs. Analog artifacts.

Any Ideas?

Hmmm, No, neither am I. SO lets leave it here for the moment.

How did you play the avi file on your TV. TV out from a PC or a divx capable DVD player?

You didn't do any transcoding, only encoding. (check the glosary).

I doubt it is any of those things you mentioned. It is probably your DVD player, see if it has any settings for picture quality, or adjust your TV to suit the picture.

The AVI and MPEG-2 file were played from Adobe Premiere Pro pass through digital camera to TV.

No that I think the setting is not on the DVD player (because I tried 2 players), but on TV. I was viewing on the Sony WEGA and that TV has 3 picture quality settings: Standard, Movie and Vivid. I was viewing on the Vivid setting. When I was viewing the VHS tape or AVI or MPEG file the picture looked great: vivid colors, sharp. However, when viewing the DVD on the same setting the picture display strange artifacts, specifically on the black color. On the black color the TV displayed little vertical distortions. It looked like it was over contrasted and over sharpened. That was not visible when I was viewing the VHS tape or AVI or MPEG file.

So try the different settings on your TV. Different sources will behave differently.

How are the Camcorder and DVD player connected to the TV. i.e composite/s-video/RGB/Component. That can make quite a big difference.

[suppafreak]

The Camera connrcted to TV using Composite cables and artifacts are not visible in any setting. The DVD player also connected using composite cables and artifacts not visible only in the Standard and Movie setting.

Sounds like a luminance problem perhaps due to a colorspace conversion.

I don't use the tools you metioned so I can't help with any specifics.

But I've seen this happen with other encoding software.

So in short look at your capture settings and the settings in your encoder.

It doesn't have anything to do with the burning.

Thanks.

What possible settings I may need to look for?

This sounds like a 'black level' issue to me. Take a look at this and see if it sounds like you.
