VirtualDub Capture Interlacing issues

KillDieMurder · Post by **KillDieMurder** » Mon Sep 13, 2004 10:13 pm

I'm attempting to capture the weapon demonstrations from Soul Calibur 2 onto my PC using my capture card (ati AIW 9600xt).
I'm capturing at 30fps, 620x480, using HuffYUV2.1.1 I tried using no compression and had the same results.
The footage plays fine but is heavily interlaced (lotsa lines). I tried adding the Deinterlace filter but that didn't help. Is there some way to fix this problem?

Can't you run the captured AVI through an IVTC or deinterlace in AVISynth (and recompress to HuffYUV again if necessary)?

How do you deinterlace an AVI using AVIsynth?
I've only used it to use VOB's in Premire and am not familiar with all of it's possibilities. Can you give me an example script?

You'd use the same plugins that you use for IVTC and deinterlacing on VOBs.

The first thing to try (assuming your video is 29.97) would be a standard IVTC:

AVISource("C:\mypath\myvideo.avi")
Telecide(order=1,post=4) #Note: use order=0 for bottom field first
Decimate(cycle=5)
I don't see the "post=4" suggested anywhere in the guides, but I personally find that it often helps clean up parts that come out combed otherwise.

If it worked, that should leave you with 23.976 progressive footage.

If that doesn't work well and leaves you with jerky motion, then you should probably try plain old deinterlacing... here's a start:

AVISource("C:\mypath\myvideo.avi")
TomsMoComp(1,5,1) #Note: make first parameter 0 for bottom field first

Note that this will give you 29.97 footage -- it doesn't change the frame rate from the original.

Many other solutions can be found on <a href="http://www.animemusicvideos.org/guides/ ... html">this page</a> of EADBAG.

Thanks for the info Scintilla.
I'll try this out when I get home.

Code: Select all

AVISource("C:\mypath\myvideo.avi") 
Telecide(order=1,post=4)
Decimate(cycle=5)

ERROR:
Avisynth open failure:
Script error: Telecide does not have a named argument "order"

Code: Select all

AVISource("C:\mypath\myvideo.avi") 
TomsMoComp(1,5,1)

ERROR:

Decimate()

Worked.

Are you using AVISynth 2.0.x instead of 2.5.x by any chance? That'll do it. I guess I've gotten too used to only giving examples that are properly phrased for 2.5 plugins.

Hmm, apparently so...

Absolutly fantastic.
I downloaded avisynth 2.5.5 from free-codecs and now none of the scripts work.
The error tells me "There is no function named Telecide" or "There is no function named TomsMoComp"

That's because you don't have the 2.5.x versions of the plugins.
