Inverse Telecin in VirtualDub- is the avi now interlaced, or not?

[sanlyn]

OK, having spent 2 months here and elsewhere reading every FAQ and guide in sight, here is the point of confusion:

I capture from VHS -> ATI AIW 8600XT card -> Virtual Dub -> .avi encoded via Huffyuv.

Looking over these .avi captures, originally recorded in 1992 over cable tv, I find that for every 5 frames I have two frames with double-image + horizontal lines. This tells me the source and the .avi are telecined. Source and .avi are NTSC, 704x480, 29.97 fps. All I wanna do in Virtualdub is make a new .avi with some noise reduction and some mild color correction. When I configure most of VirtualDub's denoisers, there's always a checkbox for "interlaced". Checking that box makes the denoiser treat the .avi as interlaced. Meanwhile, In VirtualDub's other settings area I'm activating inverse-telecine, then applying filters. Question: once I activate inverse-telecine in VirtualDub, are the filters now looking at an interlaced .avi? Or if I inverse-telecine, is the clip now entirely progressive? I would think that despite inverse-telecine, the clip is still interlaced. Don't see how it could be any other unless I go thru a full de-interlace operation.

Second: if inverse-telecine is really making this clip progressive, what happens when I open this in TMPGenc for encoding into MPEG2? Obviously I don't tell TMPGenc that this is telecined material, because supposedly VirtualDub has undone the telecine dupe frames. But do I tell TMPGenc that the .avi source file is now interlaced, or progressive? I've been telling TMPGenc that the de-telecined .avi is interlaced.

It doesn't seem I should be having a logic problem here, but for some reason I am. Maybe I've read too many Guides, all of which seem to contradict one another.

One reason I ask, is because the VirtualDub denoisers don't seem to have much effect. Looks OK in preview, but when I open the .avi in TMPGenc, it seems all the noise I supposedly removed in VirtualDub is still there. Using TMPGenc's denoiser and anti-ghost filters seems to be more effective.

Once I get these .avi's into MPEG2 and burned test DVD's, I see no (or very few) motion artifacts or other odd behavior in the results. Going the VirtualDub -> TMPGenc route is necessary because these are particularly noisy, decaying tapes, and using tricks like recording with my Toshiba DVD-R or directly into MPEG, the encoders just can't handle all the salt-and-pepper, frying noise from these old VHS tapes. I also tried pro tape players with heavy DNR from JVC and SONY, but much of the noise was still there and all the detail was lost. At least with VirtualDub I can find a compromise between noise and detail.

I figured it out myself.
Neeeverr miiind !!!

These clips are mixed: telecine+interlace+many,many, sequence changes. Guess I'll have to run them thru AviSynth.
