deinterlace-Is This The Best I Can Do?

[HelpSlip]

ive read some "blended fields" threads & a mess load of deinterlace threads & this seems to be all i can do(links below) what bothers me is the sources are EVERY (or 9 outa 10) frames interlaced, blended or what have you, but when im done processing maybe 2-3 of 7-9 frames comes out looking like this(see links) all the other frames look great , so i must be doing something wrong.....

ive even tried ivtc'ing them hopeing that the bad frames are the 1s that will be removed/combined to make less. *sources are always ntsc dvd(29.976)

but the solution isnt jumping out at me (& honestly i am having trouble keeping all the various filters & scripts organized that ive tried even with this wonderful site & avsedit)


this is the source, all frames look like this:
http://xs.to/xs.php?h=xs18&d=05094&f=source19.05.479.png

this is the outcome no matter what i seem to do, but only every few frames:
http://xs.to/xs.php?h=xs18&d=05094&f=19.05.479.png


eitherway i hope you dont mind the clutter of my thread i really do try & post my dumb questions here as little as possible

There is no magic bullet for blended fields. Sorry.

But be sure that you do have blended fields. Do separatefields() and step through the fields. Are there blends?

i still get "double" frames for lack of a better term & as you step thru it jumps kinda back & forth. so thats a "blended fields" source?

not to jump around to much but i had another source that i thought was the same (it was giving me the same kinda out come) but all the frames look "progressive" clean when you "seperatefields()". & like i said it was giving me the same outcome post processing. is there a magic bullet way i should be handling sources like that?

off the top of my head im thinking resize(unsquish)it & select just 1 or the other of the fields to use?

but back to my original problem, since those doubles are sprinkled in every so often among good frames is there a way to just remove those w/ a decimate script or sumthing (which is part of your decomb filter rite:D )

but anyhow thx its very nice that you guys take the time.

Blends in cases where the fields are not blended is usually caused by using blend deinterlacing. You need to determine whether it's true interlaced or telecined. In the former case, deinterlace with interpolation instead of blending. In the latter case, do IVTC, and if you post process, do it with interpolation, not blending.

off the top of my head im thinking resize(unsquish)it & select just 1 or the other of the fields to use? Leave that idea on your head. Do it properly with either an adaptive deinterlacer, or IVTC, as described above.

but back to my original problem, since those doubles are sprinkled in every so often among good frames is there a way to just remove those w/ a decimate script or sumthing I don't know of a reliable way to detect blended fields, and Decimate() won't do that. I don't think you'd like the result, though. The jerkiness would be worse than the ghosting. It's also technically difficult to arbitrarily decimate fields (fields have to alternate, audio must stay in sync, etc.).

I know it's hard to swallow, but there just isn't a good solution. Blending basically destroys the video.

In the former case, deinterlace with interpolation instead of blending ok so thats where i was going wrong, not interpolating. telecined sources i have no trouble w/, its when i cant find sum sort of pattern that i error. but in other words a clean finished product is attainable.

Blending basically destroys the video. ok as long as i know im not causeing it i spose i can deal.

i realized you & others have answered this in other posts ive read but its nice to have the thing your working on be specifically tackled.
