MSU Smart Deblocker

Can this plugin be used on interlaced video or not, or does it work better with progressive frames?

It seems to work best on progressive material. Deinterlacing before processing doesn't work nicely with it either. Although results do vary from source to source, my experience is that with interlaced material the results are usually noticeably worse than the source.

Hmm, I noticed that too.

In the interests of saving time. Do you think unfolding the fields in VDub, then applying Smart Deblocker, before folding the fields back, would increase the effectiveness?

[guns1inger]

Don't know how adaptive it really is. Most deblockers start form some basic assumptions regarding DCT block sizes. If you unfold then you change the block size and may well throw the deblocker off.

Still, nothing to lose by trying.

That makes sense, I guess I'll try doubling the frame rate in TMpegEnc with an adaptive deinterlace, that should keep the blocks the same size, right?

You could use VirtualDub's Bob Doubler filter instead of TMGPEnc. Unfortunately, I don't think VirtualDub has an un-bob filter so you'll need to weave with something else later.
