how to tell up field first or down field first?

I captured 480x480 interlaced avi video with Virtual VCR from a Hi8 camcorder and would likt to encode it into SVCD by CCE. How can I tell whether it is up field first or down field first?

Unless I have my A & B's mixed up...

A is top, for analogue and B is bottom, for DV.

I had a lot of frustrating moments with AVI capture and conversion until I found out that my Matrox capture card was reversing the field order - it captures at Bottom field first.

I now always check the field order from any AVI before rendering by opening the AVI in the 'Project Wizard' in TMPGenc. It does a 'Judging Field Order' test and tells you what it is.

Thanks. That is the easist way to get it.
