Aliasing Problems on LD Source (Huffyuv Capture)

[Prospero]

I've been having a bit of trouble with some aliasing on a capture I'm working on, and could use some advice. The whole thing is chronicled in a thread over at ArsTechnica (http://arstechnica.infopop.net/OpenTopic/page?a=tpc&s=50009562&f=67909965&m=2880992335) , but I'll summarize. It's an LD source capped via AVI_IO in Huffyuv, via svideo line. I already got that the field orders are reversed, but there is some aliasing that's driving me nuts. A rendered clip with smoothing can be found here (http://www.jfreeland.net/video/bobtest.avi) , and without smoothing here (http://www.jfreeland.net/video/bobtest1.avi). I also put up a 20 frame sequence of the raw cap here (http://www.jfreeland.net/video/huff.avi). The relevant portions of the VirtualDub vcf.

VirtualDub.video.filters.Add("field swap");
VirtualDub.video.filters.Add("smart smoother (1.1)");
VirtualDub.video.filters.instance[1].Config(5, 25, 0);
VirtualDub.video.filters.Add("levels");
VirtualDub.video.filters.instance[2].SetClipping(0,98,0,104);
VirtualDub.video.filters.instance[2].Config(0x0000,0xFFFF,0x00EB4B4B,0x0000,0xFFFF, 1);
VirtualDub.video.filters.Add("smart bob (1.1 beta 2)");
VirtualDub.video.filters.instance[3].Config(1, 0, 12, 1);
VirtualDub.video.filters.Add("resize");
VirtualDub.video.filters.instance[4].Config(640,278,4);


I tried the recommendations of avisyth in the arstechnica thread, but nothing looks any better than what I've already done. Anyone have any thoughts? I'm going to try some recapturing tomorrow and see if I can get any better results, and fix the field order problem, but I don't think that will fix the aliasing. Oh and if you could not mention the film or director, I would appreciate it. Thanks.

What makes you think this is something to be solved in VirtualDub? After looking at the Huffy clip you posted, I'd be partial to recapturing the movie with different settings. Do other LD captures turn out OK?

The clip isn't xvid or divx, so you tell me where to post it? You have no filtering forum. As I was using VirtualDub for processing, this was the closest place I could come up with.

I'll be trying that later, but wanted to see if anything could be done with what I have already. Other LD captures have had aliasing problems before, but nothing this bad.

I wasn't trying to attack you, I was just wondering what made you think this was a VirtualDub issue.
Now that you bring it up, this is probably better suited to the "Video Capture" forum.
Anyway; before trying particular processing settings to smooth this out.. I'd try capturing the LD using other software tools, and maybe over composite cables, rather than S-Video? Just to rule out the capture as the source of the problem.

I previously tried capturing via composite, and I remember it being worse. I might give it another try, and I also picked up a new s line. VirtualDub for capturing is my next step. Thanks for the help.
