Media Source Options problem

[hitmanyr2k]

I'm using MSP 7.0 and I'm working on a project using MPEG2 clips. However, I'm rendering my video file in an .AVI format for PC presentation. My MPEG2 clips were captured using upper field first format. Whenever I try to render my video using upper field first (along with the deinterlace box checked) in the Media Source Options the video result is terrible with jagged edges and thin black horizontal lines. The video especially looks worse in full screen. It comes out that way whether I click the deinterlace box or not.

So I went in Media Source Options and made each clip Frame-based (along with the Flicker reduction box checked) and the video came out MUCH better and noticeably cleaner when watching it in full screen. I saved my project and called it a night. When I opened my project the next day all my clips were defaulted back to Upper field first. I didn't want this so I changed a few clips back to Frame based, saved the project and closed MSP. I opened it back up immediately and looked at the clips and once again they were all defaulted back to Upper field First.

Is there a reason why Media Source Options won't hold my preferences? I don't want to have to change each clip everytime I open up my project.

And if I can't render the video using the frame-based in Media Source Options is there any way to make the video look cleaner using the Upper Field First selection? So far everything I've tried comes out messy.

Thanks for your help.

Pardon my ignorance, but why would you want to convert an mpeg2 clip back to avi? Is there a particular reason for it that I don't know of? Can't you play your mpeg files on the PC?

mpeg2 is not a format meant to be edited. It is a distribution format, highly compressed. if you re-edit that and compress it again into another format, there is no way I know to improve on the quality.

Also, afaIk, you cannot change the properties of your source clips without re-encoding them with the afoermentioned quality trade off.

I would leave them as mpg and try to use them that way.

You would have to re-render the files as frame based, not just save the project. The quality may suffer, though. As Heinz said, MPEG-2 does not support manipulation very well.
