I am using Movie Studio 8.0 and need help setting the Video Field Order??

NTSC is where the image is Drawn on screen in a Zig Zag maner.

The first pass cretes the Od lines or Top Field.

The next pass creates the Even Lines or Bootm Fields.
You need both fields Top and Bottom to make one Image.

In the Video capture settings in the Field Order drop down list it has.....First Field....Lower Field.......Both Fields.

My Q/A is the Help files say to select First Field option if it will be played on a TV. This I get

Then it says select Lower Field First if it will be DV Output?
How can this option work at all if you captured just the Lower Field of every image it would look Very Very Goffy or is this not how Interlased images work???

If you're working with DV and NTSC, just leave all that alone, don't change any of it. The default values of lower field first are correct.

This is the second time i've seen you mention "video capture settings". I'm confused about where you are seeing this. When i capture DV with VidCap there are no settings for field order, frame size, frame rate, etc. Where are you when you see these options?

Robert, File / Properties inside of Vegas isn't capture properties. Those are project properties. They don't affect capturing. When you capture DV you get whatever is on the tape the way it is on the tape, or from the converter device if you're recording from analog. You can't change anything while capturing.

Lower field first vs. upper field first are the two ways that interlaced video can be recorded. Either the odd line field had to be scanned first or the even line field. the lower (odd) field was chosen more or less arbitrarily and that's all there is to it. There's no particular technical advantage to one over the other, but they're not interchangable. DV is lower field first, which is why Vegas defaults to that.
