bad jittery effect

[PPJSmith]

I am deinterlacing using tmpgenc's deinterlace filter. But now I have a jerking, jittering problem. Someone suggested swapping the field order to fix this. Can someone give me more information on figuring out which field order is the correct one. Also if I select the correct field order will I still have to use the deinterlace filter, because I read that this filter causes a quality drop. Also I just found out also that double clicking on the interlace filter brings up some options, will any of these options help my problem?

To check your field order double click on the deinterlace option and set the interlace method to Even-Odd field (field.) Now move the slider to preview the movie, if it looks ok then your field order is correct. If the movie plays ok for a few secs, then seems to jump back a couple frames, then continue playing as normal, then your field order is incorrect. Change it and test it again.

Deinterlacing does lower quality because depending on your method you are either eliminating every other field or you are blending the two.

Whether or not you need to deinterlace depends on your source and what your doing with it. Please be more specific about exactly what it is your trying to do.
