UFF or LFF

[vlada]

Hello,
I captured a video from an analog Hi8 camcorder (AVI-MJPEG/PCM) using a standard TV card. Now I need to know if it is UFF (Uper Field First) or LFF (Lower Field First). I tried to separate the fields in Avisynth or VD, but these programs won't tell me which one is upper field and which is lower. The only chance I saw was to encode it and try it in a standalone DVD player connected to a CRT TV. Of course I did it the other way.
I just wonder why there isn't a tool which would tell me whether my movie is LFF or UFF. It should be very easy to guess if I could just separate the fields and know which one is which. Isn't there a parametr for separatefields() in Avisynth, which would allow me to set something like "upper first"? In VD I can discard field1 or field2. Which one is upper which one is lower? Or is VD trying to guess it by itself (like Avisynth does)?
Thank you. Hopefully next time I can prevent using ReStream :)

this script from the cce faq -#Use Mpeg2Source() for MPEG2 video
AVISource("E:\Video\holiday.avi")
AssumeBFF()
SeparateFields()..wil let you determine field dominance. if you run your video through this script it will play smoothly if its lower field first, jerky if its upper. usually to be sure i change the bff to tff and then the opposite should occur (lff material will be jerky and uff material will be smooth). once you can determine field dominance you know what to tell your encoder to use.

Trahald> Thank you for your reply. I just found out DgBob can also do the job. But your solution is easier.
Btw. what is correct TFF or UFF; BFF or LFF? English isn't my native language, as you can see, so I can't tell what sounds better.
