Anyone ever experiment with this or are we all just using the default settings? I have something that's particularly noisy.

You can see it in TMPG as you set it. It will keep adjusting. It mostly just blurs things more and more to compensate for the noise in the picture.

The spatial, and the temporal will help to reduce the "grains" found in alot of old/bad VHS tapes. As you increase the temporal it tends to smooth out the image too much, checking high-quality Mode helps this a little. Using this will add ALOT of rendering time.

The range slider controls maybe a 3x3 radius for 1, maybe 5x5 for 2..... I've found that anything more than 1 makes the mpeg look painted.

You might get better and faster results using Virtual Dub with (pick and choose), dynamic noise reduction, VHS toys, smoother, 2dcleaner, or others. Check out V-dub's site for those filters and others.

The problem I'm having is that usually my XVCD's come out about as good as the source videotape, but anything I tape (from S-VHS tape) from TV comes out not as good as the S-VHS tape because my cable signal is noisy. Whne I tried to use more noise reduction it does look worse but the default settings for noise reduction seem to make a noticable improvement.

Mayb I should have just stated this:
Stuff tapes elsewhere, even on regular VHS tapes looks just like the original on XVCD.
Stuff I tape looks not as good as the original.

Yes, annoying. mad.gif mad.gif mad.gif

have you tried V-Dub yet. That's what I use when ever I cap a horriable VHS. It doesn't make 'em perfect, but you can see a real difference between the original and my VCD. The VCD turns out better, it's clearer, sharper, more color, so on. I watch both on the same TV, and switch back and forth between the two to get a side by side compare.

I've found V-Dub's filters to be better and faster. My two favorite filters are VHS toys http://flaxen.dynip.com/vdf and 2d cleaner, you can that link and others at http://sauron.mordor.net/dgraft/
