Animation and analog noise

[livingfruitvirus]

I've recently switched (had to) to Comcast analog cable (digital not an option). I normally capture shows, including animated shows, but the problem with Comcast analog cable is that the analog noise is REALLY thick. As in too thick to get rid of. I've tried smoother filters, but I still get swimming blocks of artifacts. The noise also confuses the deinterlace tool (I use Decomb) into blending the wrong frames. This usually occurs with mouth movements, which are sometimes too small for the script to catch. Normally I use VirtualDub filters for smoothing but I'm willing to try AVISynth ones now. Are there any decent AVISynth smoothers for animation (and I don't mean MSmooth)?

Have you tried DeFreq? It's an avisynth filter made for removing regular analog noise. (Interlaced requires SeparateFields, or so the docs say.) Try deinterlacing then. If you'd like to clean up more:

Since that will probably leave any stray irregular noise, you can hit it with fft3dfilter or DeGrainMedia (or both). Then work with the smoothing filters, like mipsmooth, msmooth, smartssiq (more for rainbowing but most analog captures have it), and the vmtoon script, to name a few off the top of my head.

I have defreq.dll in my plugins folder, yet for some reason it still won't work.

You have to stick this in your windows folder, also:
