Field order after Decimate

[Video Dude]

I have a NTSC cartoon tv capture source clip that is bottom field first.

I apply Donald's Graft's Telecide and Decimate to restore it back to progressive frames.

I remember reading in the forum that progressive is always top field first. But when I put Info() after the Telecide and Decimate, AviSynth still indicates bottom field first.

My question is, if I am encoding the script with CCE Basic should I set the field box in CCE Basic to TFF or BFF?

Thanks.

for progressive video you don't need to bother about its field order.

Thanks for the answer.

I'll leave the CCE default which is TFF since it doesn't matter.

Just for personal interest, what do you use for capturing?

And from experience, if a progressive frame restorer
makes mistakes and your field order isn't right, then your picture will jitter occasionally which can be quite annoying.

A Canopus ADVC-100 box. Its a DV bridge that "captures" in the DV format which is bottom field first. It has s-video and rca composite inputs.

My firewire card came bundled with Ulead MediaStudio SE, so I use that for capturing software.


Since it is bff I use "order=1" in Telecide.


AviSource(C:\bff.avi)
ReInterpolate411()
Telecide(order=1, ... )
FDecimate(...)

Decomb seems to clean it up great. No jitters at all.

I was just confused at first because I read progressive was always tff but AviSynth was still indicating it was bff after the IVTC. But it seems that it does not matter.
