Default How can I change Lower field to Upper field?

Hi
Can anybody help me? How can we change project setting from lower field to upper field?
My video source is;
NTSC 72x480
Interlaced, upper field
Frame rate: 29.97
Aspect ratio: 16:9

I didnít find any Upper field project in Edius preset and also I couldnít find a way to change field rendering in project setting, what should I do?
What project settings are better for my video source? Lower field or Progressive?
Appreciate any advice in advance.

You need to render a file as upper-field first?

Why should I render files as upper field first while they are upper field?
And you didnít say what project setting is better for these files.
Thanks

are the upper field first files causing problems in the DV lower field project? if not, then no need to change anything

if they flicker, then right click the clips and change field order to lower field first, this is the correct worldwide field order for DV files

do not change the project to D1 or you will lose lots of resolution due to a bug with Edius 4.5

Not if these are MATROX PAL DV Files. Matrox insists that PAL DV is UFF and that that is correct and within spec. So if one is working with Matrox PAL DV files from, say, an RT.X2 or RT.100 then they will be UFF.

that is fine, I have used many matrox DV files supplied by customers and they work fine once I change the field order, I am not sure why matrox insist in UFF

does anyone have the bottom line on this?

if you have mixed clips (uf,lf) in one project - say standard DV (lf).

should you convert the uf clips or just conform them to the project field setting?

I just tested a matrox dv avi with upper field first in a Canopus DV lower field project

the result is perfect and does not flicker

if I change the matrox clip to lower field first, it flickers

so the moral of the story, do not alter the source field order and Edius will take care of the rest

Which brings us back to the original question.
In my experience Premiere Pro and Matrox are not so clever as Edius in being able to deal with mixed UFF and LFF footage on the timeline.
So I, too, would like to know how to render out LFF footage from Edius as UFF to be able to mix it with other UFF clips in a Matrox Pal DV project.
