Question about Interlacing

I recently purchased the latest version of Vegas Movie Studio + DVD, and I need a little help with something. Using a capture device, I have uploaded some footage from VHS to my PC in MPEG-2 format. The file plays beautifully on my PC, but when I burn it to DVD and play it on my DVD player, it seems to be a bit jerky at times, especially when something on-screen is moving rapidly - it just doesn't seem to be as smooth as it was on the source VHS, nor as smooth as it is when I play the raw file on my PC. I have not compressed the video at all, and I am using DVD+R DL discs for burning, leaving plenty of room for the footage to be burned at 100% quality - so I wouldn't expect that the bitrate is too low. Is this problem something that would be fixed with interlacing? When using video captured from VHS, should I always use the interlacing option? And finally, I notice there are options for interlacing in both Vegas Movie Studio and DVD Architect Studio - should I use that interlacing option in both programs? Or just in one of them? Does it matter which program I use it in?

Sorry for all the questions, but I want the end product to be at the best quality it can be - and there is so much in the new version of VMS + DVD that I am unfamiliar with. I'd greatly appreciate any help anyone could give me.

What you need to do is to go to the properties of the imported video and make sure it is set to upper (or top) field first. If it was a digital format (e.g. Mini-DV), you would use lower (or bottom) field first.

This worked in VMS 3 and 4 for me.

Hope this helps...

I leaned this the hard way, after doing 3 one hour videos, from old 8mm stock. I had to re-render them all.
DVD:
Field Order: Bottom (for DV) or Top (for analog)

This setting is the source of many problems, since some systems don't
say what field order they use, and some pseudo-DV systems actually capture
in analog mode. The field order is set by the capture hardware, not by the
editing program, so you can't change it in software without re-compressing
all the footage. All you can do is make sure you set this parameter right,
so that TMPGEnc knows how to encode the file. If you notice your MPEG video
flickers whenever there is fast movement, the most likely cause is a wrong field
order setting. Note that this will only be noticeable on a video monitor or TV set;
computer monitors are not interlaced, and always show odd and even lines at the same time.

Save yourself a lot of headaches and ALWAYS run a short test before committing to hours of transfer. We all have learned the hard way.
