De-Interlacing trouble

[snake-boy]

Hi,

I have two questions that I hope someone could help me out with, the first is:

- What is the difference between "Fast Deinterlace" and "Field Deinterlace" ? In other words, when should I use the one and not the other and visa-versa?

- Secondly, decomb.dll: I cannot get this to work, no matter what I try. I have followed the guides, and searched this forum for advise, but it seems I am the only one having this problem:

I setup everything as per the guide, ready to encode, but as soon as I start, gknot returns the following:

The patlabour_jap_4.log file that it reports that it cannot open above _IS_ present in that folder. I can open it fine in notepad.
I have fiddled with settings over and over and over, but each and every time, I get the same thing. :( What am I doing wrong!?

In case it helps, this is my .avs
----------------
LoadPlugin("F:\PROGRA~1\GORDIA~1\mpeg2dec.dll")
LoadPlugin("F:\PROGRA~1\GORDIA~1\decomb.dll")
LoadPlugin("D:\WINDOWS\System32\vobsub.dll")
mpeg2source("F:\encoding\patlabour_jap.d2v")
Telecide()
Decimate(cycle=5)
crop(22,46,696,386)
VobSub("F:\encoding\vts_01_0")
BicubicResize(512,304,0,0.5)
----------------

I have checked my path's, my settings and even went as far as to reinstall Gnot, but still can't get this to work.

Could ANYONE please advise? At this stage I am willing to try anything to get this to work.

many thanks

(ps, I am encoding Patlabour the Movie DVD, dvd2avi reports as 29.970fps, interlaced, so I set force film to none in dvd2avi(?)) :scared:

Fast Deinterlace is the VerticalReduceBy2 filter you see in the .avs scripts. It cuts resolution in half. Field Deinterlacing blends pixels. I often try both to see which looks better; as the choice between them is subjective and often content will make the difference.

I'm unable to diagnose your problem with DeComb. It looks to me like your first pass ran for 1 second -- not exactly the elapsed time you'd expect.

I'd try opening the .avs file in VDub, and see what things looks like. That way, if there s a failure, you may get more information. If the script with Telecide/Decimate works properly when you open the .avs file in VDub, then something else is causing the failure of the first pass.

Also, you can change the .avs script to use GreedyHMA or VerticalREduceBy2 should DeComb either fail or produce results you don't like when you inspect the frames in VDub.

Hi-

I don't think it's a Decomb problem. Do as jggimi says and open the .avs in VDub and scroll around. Does it crash? If yes, then put a # in front of the vobSub line like so:

#VobSub("F:\encoding\vts_01_0")

Open it again in VDub and scroll around. Does it still crash? If no, then move the VobSub line to the end of the .avs like so:

LoadPlugin("F:\PROGRA~1\GORDIA~1\mpeg2dec.dll")
LoadPlugin("F:\PROGRA~1\GORDIA~1\decomb.dll")
LoadPlugin("D:\WINDOWS\System32\vobsub.dll")
mpeg2source("F:\encoding\patlabour_jap.d2v")
Telecide()
Decimate(cycle=5)
crop(22,46,696,386)
BicubicResize(512,304,0,0.5)
VobSub("F:\encoding\vts_01_0")

Open again and scroll around. Does it still crash? I bet not. Haven't you posted about this problem before?
