Vegas 8 and MPEG Quality issue
by Sebastien Gravel (Dakkar) on Jul 17, 2008 at 12:45:46 am

I've put together a project with 3 different angles from 3 different camera. Two of them where mini-dv the third was a DVD one recording in MPG format. When I encode to burn in DVD Architect (version 5), the clips coming from the DVD camera are very shaky. Movements are really broken up. The clips are much degraded compared to the originals. I've tried to encode both from Vegas and Architect. I've also taken the NTSC DV preset and a custom preset with 9.5 2 pass encoding bitrate. None came out very smooth. Any suggestions?

Thanks!

What happens, if you render it out changing the field order?

Won't that mess up my other two cameras which are regular mini-DV interlaced?

First of all, 9.5 is way too high of a bitrate.
The usual recommendation is to not exceed 8.

For the DVD camcorder footage, try rendering out that material to DV-AVI and then using that on your timeline.
You will lose some quality doing this but you may save whatever hair you have left :-)

Ok, I'm too far into the project to transfert MPG to AVI on my timeline. I already have that camera mixed together with the two others (multicamera editing). Is it possible to reinterprete footage or something like that? How would I go about converting the MPG to AVI, and could I have the original media replaced with those avi files?

Thanks!

p.s I'm kind of in a rush. Need to mail it this morning...arghhh.

How many MPG files are we talking about? If it's one or two files just drop them on an empty timeline and convert them to DV AVI. then open your project and go to the Project Media window and right-click on the MPG file and select the Replace... option and navigate to the AVI file and select it. This will replace the MPG media with the AVI media everywhere in your project.

Should the DV-AVI be with lower field/upper field or progressive?

NTSC DV-AVI will be lower field.

Thanks! I was able to improve the footage following your instructions!
