Deinterlacing CGI animation

Postby Skysaurus » Mon Sep 18, 2006 9:34 pm

Hey all, I'm working on making my first AMV, using footage from Beast Wars, a computer-animated series. I've been following Ermac & Absolute Destiny's guide on how to get the ripped DVD footage ready for editing, but it seems I've hit a snag - namely, I can't seem to get the footage completely deinterlaced. At best, I can get it so that visibly interlaced frames are rare, but still noticeably present. Does anyone have any suggestions on what settings might be good for this kind of animation?

Thanks in advance. :)

What are you doing?

And what how is the original source? Telecined, fully interlaced, or other?

are you sure what you're seeing isn't blended footage? Maybe you could upload and example of what it looks like?

I've got the footage indexed into a .d2v file with an accompanying avisynth file, and now I'm trying to deinterlace the footage with VirtualDubMod.

I've been working off the assumption that the source is fully interlaced. However, I'm a bit of a n00b to this, so I might be wrong about that.

Okay, currently the avisynth file is using the following scripts:
Telecide(order=1,guide=1,show=true)
Decimate(cycle=5, mode=2)

Here is a frame that's been deinterlaced.

Here is a frame that still turned out interlaced.[/url]

that looks more like blending than interlacing.
Vicbond actually covers in his guide that the decomb plugin doesn't work as well for CG.

for that case (since I've never worked with all CG animation before) I wouldn't know what to use.

ideas: smart/adaptive blending, smart bobbing
maybe someone could provide a better suggestion

yeah it looks like blending to me too. Are you using PAL dvd's?

anyway this is the current deblend script I'm using
converttoYV12()
kernelbob(1,4)
unblend()
Decimate(4).Decimate(3)
converttoRGB24()


It's by no means perfect so feel free to have a mess around yourself.

The DVD's are NTSC with 29.97 fps.

I think they may be fully interlaced... without any sort of deinterlacing script, each frame has interlacing wherever there is movement. There's no set pattern to it.

Code: Select all
TFM(order=-1,mode=5,PP=7,field=-1,slow=2)
TDecimate()
TIsophote()


Requires TIVTC and TIsophote.

I dunno how much that'll help, but it deals with a lot of sources very nicely.
